C 语言：精准计算 e 近似值，直至项绝对值小于 10⁻⁵ 并统计项数！

```c #include <stdio.h> double factorial(int n) { double fact = 1; for (int i = 1; i <= n; i++) { fact *= i; } return fact; } int main() { double e = 1; int n = 1; double term; do { term = 1.0 / factorial(n); e += term; n++; } while (term >= 1e-5); printf("%f,%d\n", e, n - 1); return 0; } ``` ######[AI写代码神器 | 149点数解答 | 2024-10-16 14:31:22]
