一、N-S流程图;
二、运行结果;
三、源代码;
- # define _CRT_SECURE_NO_WARNINGS
- # include <stdio.h>
- # include <math.h>
-
- int main()
- {
- //初始化变量值;
- int symbol = 1;
- double denominator = 1.0, sum = 0, term = 1.0;
-
- //循环判断;
- while (fabs(term) >= 1e-6)
- {
- //运算;
- sum = sum + term;
-
- //改变变量的值;
- symbol = -symbol;
- denominator = denominator + 2;
- term = symbol / denominator;
- }
-
- //运算;
- sum = sum * 4;
-
- //输出结果;
- printf("π的近似值为:%10.8f\n", sum);
-
- return 0;
- }
