Help me do these questions. Thank so muck

Part 2: Programming Problems Q2) The function sumofN(int n) in the following C program finds the sum of all natural numbers less than n using iterative approach (e.g loop). Rewrite sumofN(int n) to use recursion instead of iterative. Make sure that you do not change the prototype of the function.- int sumOfN(int n) for (int i-n; ie; i--)t- sumsum+ i; return sum; 4 1- int main() int n; printf("Please enter a positive integer less than or equal 100: "); scanf("%d"An) ; int sum- sunOfN(n); printf( "sum of %d is %d", return 0; n, sum); bu
