以下是C语言实现展开式计算的完整代码,可以计算最后一项小于10^-8时的近似值:
```c
#include <stdio.h>
double factorial(int n) {
double result = 1.0;
for (int i = 1; i <= n; i++) {
result *= i;
}
return result;
}
int main() {
double x, ex = 1.0, term = 1.0;
int n = 1;
printf("请输入x的值:");
scanf("%lf", &x);
while (term >= 1e-8) {
term *= x / n;
ex += term;
n++;
}
printf("展开式的近似值为:%lf\n", ex);
return 0;
}
```
