Being new to programming and c++, I am unable to understand exactly
what is going on in this example factorial program out of the c++
Demystified book. When I input a 3, it returns 6 and I'm not sure how.
The thing that confuses me is the line that says total *=counter; If
total = 1, and counter = 3(which is the number I inputted), then total
*=counter should read as 1 = 1 * 3 which should output a 3. Can someone
clarify this for me?
#include <iostream>
using namespace std;
int main()
{
int number, counter, total = 1;
cout <<"Enter a number to see the factorial: ";
cin >> number;
cout << "The factorial of " << number << " is ";
for (int counter = 1; counter <= number; counter++)
total *= counter; //how can this return a 6 since total = 1 and counter
= 3 ??
cout << total;
return 0;
}
