Answer explanation

The char data type takes one byte in the memory.

#include<stdio.h>

struct st

{

    int x;

    static int y;

};

int main()

{

    printf("%d", sizeof(struct st));

    return 0;

}

Predict output of following program

int main()

{

    int i;

    int arr[5] = {1};

    for (i = 0; i < 5; i++)

        printf("%d ", arr[i]);

    return 0;

}

union test

{

    int x;

    char arr[8];

    int y;

};

 

int main()

{

    printf("%d", sizeof(union test));

    return 0;
