Point out the error in the program 
#include<stdio.h>
int f(int a)
{
  a > 20? return(10): return(20);
}
int main()
{
    int f(int);
    int b;
    b = f(20);
    printf("%d\n", b);
    return 0;
}

A Error: Prototype declaration

B No error

C Error: return statement cannot be used with conditional operators

D None of above

ANS:C - Error: return statement cannot be used with conditional operators

In a ternary operator, we cannot use the return statement. The ternary operator requires expressions but not code.
