See the bottom for how to submit your work.

Due: Before 0800 on next class day

(10 pts) Read today's lecture notes. Honestly declare how you read the notes.
1. (10 pts) I read the notes carefully. I have a good understanding of the topics therein.
2. (10 pts) I read the notes carefully, but I don't really understand the following points well:
3. (0 pts) I didn't read the notes carefully.

[90pts] Change the following C++ program to C (with filename hw.c). You must verify correctness by compiling with gcc:

// A fancy C++ program that calculates n!
#include <iostream>
using namespace std;

int factorial(int);
  
int main() 
{
  int num;
  cout << "Enter a number: ";
  cin >> num;

  int fac = factorial(num);
  cout << num << "! = " << fac << endl;
  
  return 0;
}

// Compute n!
int factorial(int n) 
{
  int prod = 1;
  for( int i = 1; i <= n; i++ ) 
    prod *= i;
  
  return prod;
}

Example runs:

~/$ ./hw
Enter a number: 4
4! = 24

~/$ ./hw
Enter a number: 8
8! = 40320
