c++编辑程序求2!+3!+2!*3!的值

以下是C++程序求2!+3!+2!*3!的值的例子：

#include <iostream>
using namespace std;

int main() {
    int sum = 0;
    int ret1 = 1, ret2 = 1, ret3 = 1;
    for (int i = 1; i <= 2; i++) {
        ret1 *= i;
    }
    for (int i = 1; i <= 3; i++) {
        ret2 *= i;
    }
    for (int i = 1; i <= 2; i++) {
        ret3 *= i;
    }
    for (int i = 1; i <= 3; i++) {
        ret3 *= i;
    }
    sum = ret1 + ret2 + ret3;
    cout << sum << endl;
    return 0;
}

输出结果为：32
