使用switch case语句编写的C程序，用于计算几何图形的面积

#include void main(){ int fig_code; float side, base, length, breadth, height, area, radius; printf("-------------------------

"); printf(" 2 --> Rectangle

"); printf(" 3 --> Triangle

"); printf(" 4 --> Square

"); printf("-------------------------

"); printf("Enter the Figure code

"); scanf("%d", &fig_code); switch(fig_code){ case 1: printf(" Enter the radius

"); scanf("%f",&radius); area=3.142*radius*radius; printf("Area of a circle=%f

", area); break; case 2: printf(" Enter the breadth and length

"); scanf("%f %f",&breadth, &length); area=breadth *length; printf("Area of a Rectangle=%f

", area); break; case 3: printf(" Enter the base and height

"); scanf("%f %f", &base, &height); area=0.5 *base*height; printf("Area of a Triangle=%f

", area); break; case 4: printf(" Enter the side

"); scanf("%f", &side); area=side * side; printf("Area of a Square=%f

", area); break; default: printf(" Error in figure code

"); break; } }
