Consider the following C program :

#include < stdio.h >
 int main ()  {
            int arr [] = {1,2,3,4,5,6,7,8,9,0,1,2,5}, *ip = arr+4;
             printf ("%d\n", ip[1]);
             return 0;
}

The number that will be displayed on execution of the program is _______.

Consider the following C function.

void convert(int n){

    if(n < 0)

        printf("%d",n);

    else {

        convert(n/2);

        printf("%d",n%2);

    }

}

Which one of the following will happen when the function convert is called with any positive integer n as argument?

Consider the following C program :

#include<stdio.h>

int r()

{

        static int num=7;

        return num--;

}

int main()

{

        for(r();r();r())

        printf("%od ",r());

        return 0;

}

Which one of the following values will be displayed on execution of the programs?

Consider the following C program :

#include <stdio.h>

int main(){

    float sum = 0.0, j = 1.0, i = 2.0;

    while (i/j > 0.0625){

        j = j + j;

        sum = sum + i/j;

        printf("%f\n", sum);

    }

    return 0;

}
