Which of the following statements are correct about the below program? 

#include<stdio.h>
int main()
{
    int i = 0;
    i++;
    if(i <= 5)
    {
        printf("IndiaMax\n");
        exit(0);
        main();
    }
    return 0;
}

A. The program prints 'IndiaMax' 5 times
B. The program prints 'IndiaMax' one time
C. The call to main() after exit() doesn't materialize.
D. The compiler reports an error since main() cannot call itself.

Which of the following statements are correct about the below C-program? 

#include<stdio.h>
int main()
{
    int x = 10, y = 100%90, i;
    for(i=1; i<10; i++)
    if(x != y);
        printf("x = %d y = %d\n", x, y);
    return 0;
}
1 : The printf() function is called 10 times.
2 : The program will produce the output x = 10 y = 10
3 : The ; after the if(x!=y) will NOT produce an error.
4 : The program will not produce output.

A. 1
B. 2, 3
C. 3, 4
D. 4

{
    int n = 0, y = 1;
    y == 1 ? n=0 : n=1;
    if(n)
        printf("Yes\n");
    else
        printf("No\n");
    return 0;
}

2: switch is useful when we wish to check whether a value falls in different ranges.
3: Compiler implements a jump table for cases used in switch.
4: It is not necessary to use a break in every switch statement.

A. 1,2
