Consider the following C program:

        #include < stdio.h >
         int jumble (int x, int y)  {
               x = 2 * x + y ;
               return x ;
         }
         int main ( )  {
               int x=2, y=5 ;
               y = jumble (y, x) ;
               x = jumble (y, x) ;
               printf ("%d \n", x) ;
               return 0 ;
         }

The value printed by the program is ______.

Consider the following C program:

       #include < stdio.h >
       int main()
       {
           int a[] = {2, 4, 6, 8, 10} ;
           int i, sum = 0, *b = a + 4 ;
           for (i = 0; i < 5; i++)
                 sum = sum + (*b - i) - *(b - i) ;
           printf ("%d\n", sum) ;
           return 0 ;
        }

The output of the above C program is _________.

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?
