A c# program to find the factorial of an integer value given from the console! please guys help me out!

In Java using Recursion

 public static int factorial(int value){
       if(value<=1){
           return 1;
        }else{
           return value * factorial(value -1);
        }
 }

Saw the post a little bit too late.

//in C++, using recursion;


#include <iostream>

int factorial (int x); //function prototype

using namespace std;

int main (){

int x;
int fact;

cout << "\nEnter a positive integer: \t";
cin >> x;

fact = factorial(x);

cout << "The factorial of " << x << " is " << fact;

return 0;
}

//function definition;

int factorial (int x){

if(x == 1) {return 1;}

else {return x*factorial(x-1);}

}



//in C++, using iteration;

#include <iostream>

using namespace std;

int main (){

int x;
int fact = 1;

cout << "\nEnter a positive integer: \t";
cin >> x;

cout << "The factorial of " << x << " is ";

//forever loop
for(; {

if (x == 1){
break;
}

else {
fact = fact * x;
x--;
}
}

cout << fact << endl;

return 0;
}
