求C语言编程矩形面积周长对角线编写程序,将计算长方形的面积、周长和对角线长,分别写成三个函数,函数参数为长方形的两个边长
1个回答

#include "stdio.h"

//面积

double area(double len,double wid){return len*wid;}

//周长

double circle(double len,double wid){return 2*(len+wid);}

//对角线

double duijiaoxian(double len,double wid){return sqrt(len*len+wid*wid);}

void main()

{

printf("请输入长宽：n");

double length,width;

scanf("%f%f",&length,&width);

printf("面积为：n",area(length,width));

printf("周长为：n",circle(length,width));

printf("对角线长为：n",duijiaoxian(length,width));

}
