C语言程序,计算三角形的面积程序如何书写?
C语言程序,计算三角形的面积程序如下:c#include<stdio.h>,#define PI3.14159,int main(),double base,height,area;printf(请输入三角形的底边长:);scanf(%lf,&base);printf(请输入三角形的高:);scanf(%lf,&height);area=0.5*base* height;printf(三角形的面积为:%.2...

计算圆的面积的程序
1. 用C语言来实现计算圆的面积的程序如下:include "stdio.h"define PI 3.14159 int main(){ float nR;float nArea;printf("请输入圆的半径:");scanf("%f",&nR);nArea = PI*nR*nR;printf("圆的面积是:%f\\n",nArea);return 0;} 2. 用C++语言来实现计算圆的面积的程序如下:include<...

include <stdio.h> define PI 3.14159 int main(){ int r,ret;printf("Please input r:");scanf("%d",&r);if(r>=0){ret=r;```(你想写的)} } 加一个判断语句不就行了么?而且你为什么要用u%,d%就可以了(半径为整数)。

...要求定义如下宏常量ON #define PI 3.14159?
在C语言中,可以使用宏定义来定义常量。可以按照如下方式来实现输入圆的半径,求圆的周长和面积的程序:include <stdio.h> define PI 3.14159 define ON 1 int main(){ double r, c, s;while (ON){ printf("请输入圆的半径:");scanf("%lf", &r);if (r <= 0){ printf("半径不能...
