Q 1 - What is the output of the below code snippet?
#include<stdio.h>
main()
{
int a = 1;
float b = 1.3;
double c;
c = a + b;
printf("%.2lf", c);
}
Answer : A
Explanation
2.30, addition is valid and after decimal with is specified for 2 places.
Q 2 - What is the output of the following program?
#include<stdio.h>
main()
{
float t = 2;
switch(t)
{
case 2: printf("Hi");
default: printf("Hello");
}
}
Answer : D
Explanation
Error, switch expression cant be float value.
Q 3 - Identify the invalid constant used in fseek() function as whence reference.
Answer : C
Explanation
SEEK_BEG, all the rest are valid constants defined in stdio.h
Answer : B
Explanation
There is no such data type called string in C language.
Q 5 - What is the output of the following statement?

main()
{
printf("%d", !0<2);
}
Answer : B
Explanation
Priority of ! is greater than <. Relational operator returns 1 if relation between the expressions is true otherwise 0.
Q 6 - int fun();- The declaration indicates the presence of a function defined inside the current module or in the same file.
Answer : A
Explanation
The function definition can even appear in another source code and can be linked from library while linking.
Answer : A
Explanation
Logical NOT operator will make false.
Q 8 - In the following code, what is 'P'?
Typedef char *charp; const charp P;
Answer : A
Explanation
Const charp P;
Although, the code itself indicates the keyword "const", so that; P is a constant.
Q 9 - Choose the correct order from given below options for the calling function of the code a = f1(23, 14) * f2(12/4) + f3();?
Answer : D
Explanation
Evaluation order is implementation dependent.
Q 10 - Choose the function that is most appropriate for reading in a multi-word string?
Answer : D
Explanation
gets (); = Collects a string of characters terminated by a new line from the standard input streamstdin
