C++ Program to calculate factorial of a given number [DEVCPP/GCC]

STEPS

1. Initialize variable fact with 1.
fact = 1;

2. Multiply fact with the given number.
fact = fact * num;

3. Decrement number by 1.
num-- ;

4. Repeat steps 2-3 till num>0.

PROGRAM

//Program to calculate factorial of a given number

#include <iostream>

using namespace std;

int main()
{
int i,n;
long fact=1;

cout<<"ENTER THE NUMBER: ";
cin>>n;

while(n!=0)
{
fact=fact*n;
n--;
}

cout<<"FACTORIAL IS: "<<fact;
return 0;
}
