编程计算S=1!+2!+3!+4!+…+10!的值。语言代码

以下是Python代码，用于计算S=1!+2!+3!+4!+…+10!的值：

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n-1)

S = 0
for i in range(1, 11):
    S += factorial(i)

print(S)

输出结果为：4037913

C++语言编程计算s=1! +2! +3! +……n! n是正整数

以下是计算s的C语言代码：

#include <stdio.h>

int main() {
    int n, i, j, factorial = 1;
    double s = 0;
    printf("请输入一个正整数n：");
    scanf("%d", &n);
    for (i = 1; i <= n; i++) {
        factorial *= i;
        s += factorial;
    }
    printf("s = %.0f\n", s);
    return 0;
}

这个程序会让用户输入一个正整数n，然后计算出s的值，并输出结果。
