Program help

[compsci]

I have most of the program I just need help with A-C


Translate the following algorthm into a main function for a C++ program.

1. Read an integer number- N
2. While N is not greater than zero
2.1 Read another number - N.
3. Set the product to one.
4. For each value 1 to N
4.1 product = product * value
5. Print the product


Write functions for the following.
A. Write steps 1 and 2 above as a function which reads and returns the value of N that is read.






B. Write steps 3 and 4 as a function that has N as the value parameter and computes the factorial of N.







C. Rewrite the main function using the functions in A and B.
#include <iostream>
using namespace std;

int funct (int n){
int p;
cout << "Enter a number:";
cin >> n;
p = n;
return p;
}


int main()
{
int n;

cout << "Enter a number:";
cin >> n;

while (n<=0)
{
cout << "Please a positive number";
cin >> n;
}

int product = 1;
for(int x = 1; x<=n; x++)
{
product = product*x;
}
cout << product << endl;

cout << funct (n) << endl;



return 0;
}

int factorial(int N);

cout << funct (n) << endl;



return 0;

There I did the first two for you, you can do the rest.
