Question

Jack and Jill are novice programmers. They are asked to write a function in C Language that calculates the Tables (1 to 10) of a number and then prints its sum.

E.g. if we consider the number as 8 then the program should calculate and print the sum of (8*1 + 8.2 + ... + 8.10) = (8 + 16 + ... + 80) 

    //main program, which calls the functions written by them

int main() {

   int n;

   printf("Enter a number \n");

   scanf(“%d”,&n);

   printf("%d \n”,jack(n,1));

   printf("%d \n”,jack(jill(n,10));

   return 0;

}

 

 

    Line

No.     // Jack's Function

  1. int jack(int n, int i) {
  2. if(i <= 9)
  3. n = n*i + jack(n, i+1);
  4. return n;
  5. }

 

 

    Line

No.     // Jill's Function

  1. int jill(int n, int i) {
  2. if(i != 0){
  3. n = jill(n, i-1) + n*i;
  4. return n;
  5. }
  6. else
  7. return n*i;
  8. }


Choose the correct option

  1. Both the functions will do as mentioned in the question
  2. Only Jack's function will work correctly
  3. Only Jill's function will work correctly
  4. None of the functions will work correctly
