Factorial Program in C++

This C++ Program computes factorial of a given integer. Here the factorial is computed by multiplying all the numbers upto the given input.

Here is source code of the C++ program which computes the factorial of a given number. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

```

 * C++ program to compute factorial of a given integer

```
 */
```
```
#include<iostream>
```
```
using namespace std;
```
```
 
```
```
int main()
```
```
{
```
```
    int fac;
```
```
    long long val = 1;
```
```
 
```
```
    cin >> fac;
```
```
    cout << endl;
```
```
    for (int i = 2; i <= fac; i++)
```
```
        val = val * i;
```

    cout << "The factorial of " << fac << " is " << val << endl;

```
 
```
```
    return 0;
```
```
}
```

$ g++ main.cpp
$ ./a.out
Enter the integer : 10
The factorial of 10 is 3628800
