Sample Infosys Pseudo Code Questions with Solutions

1. What is the output?

#include<stdio.h>
int main()
{
    for (int x = 10; x >= 0; x--) {
        int z = x & (x >> 1);
        if (z)
            printf("%d ", x);
     }
    
}

Here, in the given code, >> is the bitwise right shift operator and x>>y => x/(2^y) and & is the bitwise and operator and gives 1 only if both bits are same. Now, for x = 10, (10>=0) z = 10 & (10>>1) => z = 10 & 5 => z=10. Similarly for x= 9, 8, 5, 4, 2, 1 and 0 , z will be zero and for x=7, z will be 3 , for x= 6, z will be 2 and for x=3, z will be 1 for x=7, 6, and 3 z is non zero so the will get printed on the output screen. Hence, we get output as 7 6 3

    int a = 100;
    printf("%0 %x", a);

In this question %0 will cancel out the a, while %x will get printed
but,
if we only write printf("%x"); without passing any parameter for x,
it will show an error.

3. What is the output?

#include<stdio.h>
int main() 
{
    typedef int num;
    num bunk = 0.00;    
    printf("%d", bunk);
    return 0;

Integer part of 0.00 is equal to 0.
Hence only zero will be printed with printf("%d", bunk), when 0.00 is passed, because %d stands for integer.

4. What is the output?

#include<stdio.h>
int main(){
    float x = 0.0;
    long int y = 10;
    printf("%d", sizeof(y) == sizeof(x+y));
    return 0;

sizeof(x), that is float, is 4
sizeof(y), that is long int, is 8
sizeof(x+y) that also comes out to be float will have size = 4

here it is asking sizeof(y) == sizeof(x+y)
i.e 8 == 4
"==" operator gives result in either 0 or 1
so answer is zero.

} while(go--);
printf ("%d\n", num);

here it is asking sizeof(x) == sizeof(x+y)
i.e 4 == 4
"==" operator gives result in either 0 or 1
so answer is 1.
