C Programming Language : Basics

1. What will be the output of the code ________?


    #include<stdio.h>

    int main()

    {

        int i = -3;

        int j = i % 2;

        printf(“%d\n”, j);
         
    }

-1

Compile time error

2. What will be the output of the code ________?


    #include<stdio.h>

    int main()

    {

        int i = 1;

        int x = i++, y = ++i;

        printf("%d % d\n", x, y);

        return 0;

    }

1, 2

1, 3

0, 1

Undefined

3. What will be the output of the code ________?


    #include<stdio.h>

    void main()

    {

        int i = 65;

        int j = sizeof(i++);

        printf("i is %d", i);

    }

i is 65

i is 66

i is A

Run time error
