DATA can accept input from the user, perform certain computations, then have the output redirected to a file named DATA, instead of showing it on the screen. These frequently asked sample questions on C Language are given with correct choice of answer that you can check instantly. Syntax errors, on the other hand, deal with incorrect commands that are misspelled or not recognized by the compiler. The solution offered in the C language is known as the switch-case structure. Flowcharts are made of symbols, with each symbol in the form of different shapes. Sequential control follows a top to bottom flow in executing a program, such that step 1 is first perform, followed by step 2, all the way until the last step is performed. What is the output of this program? Explanation: It will give compile time error since x is not declared. In C programming, there is a data structure known as queue. Next in line are the relational operators <, <=, >= and >. There are actually two ways you can do this. What is the output of this program? For example: to store the 10 test results of 1 student, one can use 10 different variable names (grade1, grade2, grade3... grade10). D. give garbage value. Therefore, source codes are compiled using a compiler. All reserved words must be written in lowercase; otherwise the C compiler would interpret this as unidentified and invalid. }, A. letsfindcourse 15 3 26) When is the "void" keyword used in a function? After the file was opened by the fopen() function, the fseek would require three parameters to work: a file pointer to the file, the number of bytes to search, and the point of origin in the file. printf("hello\b\b\bworld\n"); For example: you can have a code like " printf ("Hello\n\n\'World\'") " to output the text "Hello" on the first line and "World" enclosed in single quotes to appear on the next two lines. <> is incorrect. For each turn on the outer loop, the inner loop is first performed. 71) When is a "switch" statement preferable over an "if" statement? However, recall that reserved words are express in lowercase, so the C compiler will not interpret this as a reserved word. return 0; 4. The outcome will be TRUE. One is to use the increment operator ++ and decrement operator --. 1. myName = "Robin"; You cannot use the = sign to assign values to a string variable. Use the fseek() function to perform random access input/ouput on a file. Therefore, NAME, name and Name are three uniquely different variables. C Programming Questions and Answers has been designed with a special intention of helping students and professionals preparing for various Certification Exams and Job Interviews.This section provides a useful collection of sample Interview Questions and Multiple Choice Questions (MCQs) and their answers with appropriate explanations. Assigning multiple characters in an int in C language, Multiple Choice Questions on all CS topics. When using Call by Value, you are sending the value of a variable as parameter to a function, whereas Call by Reference sends the address of the variable. 100 multiple-choice questions in C++ : Continental Mathematics League four contests in C++ 1998-2001.. [Skylight (Firm); Continental Mathematics League. D. Compilation Error. int main = 3;

# define scanf "%s Find best course " While this operator is correctly interpreted as "not  equal to" in writing conditional statements, it is not the proper operator to be used in C programming. acknowledge that you have read and understood our, GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Interview Preparation For Software Developers, Output of C Program | Set 30 (Switch Case), Output of C programs | Set 33 (rand() and srand()), Output of C programs | Set 39 (Pre Increment and Post Increment), Output of C programs | Set 40 (File handling), Output of C programs | Set 44 (Structure & Union), Output of C programs | Set 47 (Decision and Control Statements), Output of C programs | Set 49 (Operators), Output of C programs | Set 50 (Control Structures), Output of C programs | Set 53 (Operators), Output of C programs | Set 55 (Ternary Operators), Output of C programs | Set 55 (Shift Operators), Output of C programs | Set 56 (While loop), Output of C programs | Set 58 (operators), Output of C programs | Set 59 (Loops and Control Statements), Output of C programs | Set 60 (Constants), Output of C programs | Set 62 (Declaration & Initialization). Explanation: A C program can have same function name and same variable name. 8. This means that program flow may not necessarily move from one statement to the next one, but rather some alternative portions may need to be pass into or bypassed from, depending on the outcome of the conditional statements. C. letsfindcourse 14 3 If you have 10 conditions and all but 1 fails to evaluate as TRUE, the entire condition statement is already evaluated as FALSE.

32) How do you generate random numbers in C? Which statment is true about the given code . That's because memory in this structure can be allocated and remove in any particular order. Comments are a great way to put some remarks or description in a program. In the second expression, the current value of variable a would the one to be used in an operation, before the value of a itself is incremented. FALSE. }. The strcat function. Each side can further branch to form additional nodes, which each node having two pointers as well. int main()

No. For example: if you have a declaration that says "intscores[5];", then you have 5 accessible elements, namely: scores[0], scores[1], scores[2], scores[3] and scores[4]. Each element is assigned a number from 0 to number of elements-1. What is the output of this program? #include No. For example, the statement "x++" means to increment the value of x by 1. C. Invalid Syntex In the case of "tolower()", the code "#include " must be present at the beginning of the program. Compound statements can also be executed within a loop. Both will also hold a particular value. These Multiple Choice Questions (mcq) should be practiced to improve the C programming skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations. Comments are mostly for the guidance of the programmer only and do not have any other significant use in the program functionality. 9. 79) Dothese two program statements perform the same output? A Computer Science portal for geeks. D. Compilation Error. However, switch statements can only evaluate integer and character data types.

Within the main function lies the variable declaration and program statement. followed by a junk value When the user presses the enter key to end the input, the entire line of characters is stored to a string variable. printf("hello\rworld\n"); If that function will not return a value, such as when the purpose of a function is to display some outputs on the screen, then "void" is to be placed at the leftmost part of the function header. In this scenario, the inner loop is performed a number of times as specified by the outer loop. void main() B. hello5 C. Compile time error For example, you can write printf("10%%") to have the output appear as 10% on the screen. int main() The = symbol is often used in mathematical operations. For example, the statement "x++" means to increment the value of x by 1. 6. return 0; Preprocessor directives are placed at the beginning of every C program. D. print hello and terminates, Explanation: Firstly inner printf executes and will print hello now this return the number of character printed that is 5 and this will be printed by outer printf . This unstructured approach to coding is usually attributed to lack of experience on the part of the programmer. The correct statement would be: strcpy(myName, "Robin"); 47) How do you determine the length of a string value that was stored in a variable? return 0; 62) Is this program statement valid? printf("%d", scanf("%d %d",&a,&b));

int main() This also means that not all codes may be executed, and there are alternative flows within. It has to do with the parsing process and compilation of the code. It is also possible to create user defined functions for sorting, such as those based on the balloon sort and bubble sort algorithm. 72) What are global variables and how do you declare them? The switch statement is best used when dealing with selections based on a single variable or expression.

Instead, you pass to it a pointer that will point to the array first element in memory. Difference between DELETE, DROP and TRUNCATE, Python Program for Sum the digits of a given number, How to find index of a given element in a Vector in C++. They contain two essential things: the definitions and prototypes of functions being used in a program. To do this, you indicate the name of the array without the brackets. To insert the quote character as part of the output, use the format specifiers \' (for single quote), and \" (for double quote). An endless loop can mean two things. More spaces can be added by inserting more \n characters. 7) What is variable initialization and why is it important?

46) What is wrong with this statement?

Placing & means whatever integer value is entered by the user is stored at the "address" of the variable name. For example, you can assigned a constant named PI and give it a value 3.1415  . 40) What are the different types of control structures in programming? The values that are being passed into the called function are referred to as actual arguments. Output of the Program | Pointer to a Constant or Constant Pointer? The logical operators && and || are next evaluated. 37) In C programming, what command or code can be used to determine if a number of odd or even? 82) What is the difference between text files and binary files? 91) Can you pass an entire structure to functions? D. variable! This is a common problem for beginners because quotes are normally part of a printf statement.

if input a is 1 and b is 2 To assign or retrieve the value of a particular element, refer to the element number. A random access file lets you jump directly to the target address where data is located. In the case of "x++", another way to write it is "x = x +1". B. variable! 24) Can two or more operators such as \n and \t be combined in a single line of program code? There are actually two ways you can do this. Output of the Program | Use Macros Carefully! 15) Which of the following operators is incorrect and why? Output redirection allows a program to have its output saved to a file. 2. Explanation: "" for a backspace, means if u print it, cursor will print and come back 1 character . ' Experience.

int main() #include {

Since the value of s is 10, s >= 10 evaluates to TRUE because s is not greater than 10 but is still equal to 10. s< 25 is also TRUE since 10 is less then 25. It is made up of the commands and other English-like keywords that are supposed to instruct the computer what to do.

57) What would happen to X in this expression: X += 15;  (assuming the value of X is 5). i = printf("letsfindcourse"); For example: 10 % 3 = 1, meaning when you divide 10 by 3, the remainder is 1. FALSE. C. Will give Compilation Error Previous data that was stored on that file will be erased. Writing code in comment? { You can write it in code as: 38) What does the format %10.2 mean when included in a printf statement? For example, if you have a program named COMPUTE, typing this on the command line as COMPUTE >DATA can accept input from the user, perform certain computations, then have the output redirected to a file named DATA, instead of showing it on the screen.
