C语言实现：用级数近似计算自然常数e的前n+1项和

```c #include <stdio.h> double factorial(int n) { if (n == 0 || n == 1) { return 1; } else { double result = 1; for (int i = 2; i <= n; i++) { result *= i; } return result; } } int main() { int n; scanf("%d", &n); double sum = 1; for (int i = 1; i <= n; i++) { sum += 1.0 / factorial(i); } printf("%.8f\n", sum); return 0; } ``` ######[AI写代码神器 | 167点数解答 | 2024-10-12 20:03:17]
