What will be the output of the following C code?

#include <stdio.h>
int main()
{
    int x = 1, y = 2;
    int z = x & y == 2;

    printf("%d\n", z);
}

What will be the output of the following C code considering the size of a short int is 2, char is 1 and int is 4 bytes?

#include <stdio.h>
int main()
{
    short int i = 20;
    char c = 97;
    printf("%d, %d, %d\n", sizeof(i), sizeof(c), sizeof(c + i));
    return 0;
}

What will be the output of the following C code?

#include <stdio.h>
void main()
{
    int x = 97;
    int y = sizeof(x++);
    printf("X is %d", x);
}

What will be the output of the following C code?

#include <stdio.h>
void main()
{
    int a = 2 + 4 + 3 * 5 / 3 - 5;
    printf("%d", a);
}

{
    a,b,c=5,d,e
};
main()
{
    printf("Enter the value for a");
    scanf("%d",a);
    printf("%d",a);
}

What will be the output of the following C code?

#include <stdio.h>
void main()
{
    int b = 6;
