Consider the following C program:
void foo (int n, int sum) {
int k = 0, j = 0;
if(n==0) return;
k=n%10; j = n /10;
sum = sum + k;
foo(j, sum);
printf("%d",k);
}
int main () {
int a = 2048, sum = 0;
foo(a, sum);
printf("%d\n", sum);
}
What does the above program print?
A
8, 4, 0, 2, 14
B
8, 4, 0, 2, 0
C
2, 0, 4, 8, 14
D

Consider the following C program:
double foo(double); /* Line 1 */
int main () {
double da, db;
//input da
db = foo(da);
}
double foo(double a){
return a;
}
The above code compiled without any error or warning. If Line 1 is deleted, the above code will show:
A
no compile warning or error
B
some compiler-warnings not leading to unintended results
C
some compiler-warnings due to type-mismatch eventually leading to unintended results
D
compiler errors

Consider the following C program
main ( )
{
int x, y, m, n;
scanf("%d %d", &x, &y);
/* Assume x > 0 and y > 0 */
m=x; n=y;
while(m!=n)
{
if(m>n)
m=m-n;
else
n=n-m;
}
printf("%d", n);
}
The program computes
