Q 1 - What is the output of the below code snippet?
#include<stdio.h>
main()
{
for(;;)printf("Hello");
}
Answer : A
Explanation
infinite loop, with second expression of for being absent it is considered as true by default.
Q 2 - What is the output of the following program?
#include<stdio.h>
{
int x = 1;
switch(x)
{
default: printf("Hello");
case 1: printf("hi"); break;
}
}
Answer : B
Explanation
Hi, control reaches default-case after comparing the rest of case constants.
Q 3 - What is the output of the following program?
#include<stdio.h>
main()
{
int a[] = {2,1};
printf("%d", *a);
}
Answer : C
Explanation
2, as a refers to base address.
Q 4 - What is the output of the following program?
#include<stdio.h>
int x = 5;
int* f()
{
return &x;
}
main()
{
*f() = 10;
printf("%d", x);
}
Answer : D
Explanation
The returned address is global variables and 10 being stored in it. Therefore x is 10.
Q 5 - What is the output of the following statement?
#include<stdio.h>
main()
{
printf("%d", -1<<1 );
}
Answer : B
Explanation
A negative number stored in twos compliment of positive number. After shifting we get 1110, which is equivalent to -2.
Answer : A
Explanation
#include <stdio.h>
int main()
{
longintdecimalNumber,remainder,quotient;
intbinaryNumber[100], i = 1, j;
printf("Enter any decimal number: ");
scanf("%ld",&decimalNumber);
quotient = decimalNumber;
while(quotient!=0){
binaryNumber[i++]= quotient % 2;
quotient = quotient / 2;
}
printf("Equivalent binary value of decimal number %d: ",decimalNumber);
for(j = i -1 ;j> 0;j--)
printf("%d",binaryNumber[j]);
return0;
}
Q 7 - Which standard library function can return a pointer to the last occurrence of a character in a string?
Answer : B
Explanation
The strrchr() function finds string for the last occurrence of a character and place the pointer to the last occurrence of character.
Q 8 - In the given below code, theP2is
Typedef int *ptr; ptr p1, p2;
Answer : B
Explanation
Ptr is an alias to int*.
Q 9 - Choose the correct unary operators in C a) !, b) ~, c) ^&, d) ++
Answer : A
Explanation
In C, these are the unary operators,
Logical NOT = ! Address-of = & Cast Operator = ( ) Pointer dereference = * Unary Plus = + Increment = ++ Unary negation =
Q 10 - The library functionstrrchr() finds the first occurrence of a substring in another string.
Answer : B
