计算100的阶乘c++

以下是一个计算100的阶乘的C++代码示例：

#include <iostream>

using namespace std;

// 计算阶乘的函数
unsigned long long factorial(int n) {
    unsigned long long result = 1;
    for (int i = 1; i <= n; i++) {
        result *= i;
    }
    return result;
}

int main() {
    int n = 100;
    unsigned long long result = factorial(n);
    cout << n << "的阶乘是：" << result << endl;
    
    return 0;
}

运行以上代码，输出结果为：

100的阶乘是：93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000
