请编写程序计算1!+2!+3!+…+n!的前10项之和。

以下是C语言程序设计计算1!+2!+3!+…+n!的前10项之和的代码：

#include <stdio.h>

int main()
{
    int n = 10;
    double sum = 0, factorial = 1;
    for (int i = 1; i <= n; i++)
    {
        factorial *= i;
        sum += factorial;
    }
    printf("The sum of the first 10 factorials is: %lf", sum);
    return 0;
}

输出结果为：The sum of the first 10 factorials is: 4037913.000000

以下是Python计算1!+2!+3!+…+n!的前10项之和的代码：

n = 10
sum = 0
factorial = 1
for i in range(1, n+1):
    factorial *= i
    sum += factorial
print("The sum of the first 10 factorials is:", sum)

输出结果为：The sum of the first 10 factorials is: 4037913
