小编dou*_*one的帖子

我是C++的新手,两周前我开始用C++学习编码.为什么我的代码在构建和运行时总是给我结果0？请帮忙

# include <iostream>
# include <string>

using namespace std;

int main ()
{
    int input = 1;
    cout << "input your number : \n";
    cin >> input;

    int faktorial = 1;

    for(int i=1;i<=input;i++)
    {
        faktorial = faktorial * i;
    }
    cout << "factorial value from number  " << input << " is " << faktorial << endl;
}
