问题

编写一个程序，用switchcase计算三角形、正方形、圆形、长方形和多边形的面积。

解决方案

根据案例编号，计算三角形、正方形、圆形、矩形和多边形的面积。

用于查找三角形面积的逻辑如下-

输入三角形a,b,c的边

s=(float)(a+b+c)/2;
area=(float)(sqrt(s*(s-a)*(s-b)*(s-c)));

用于查找正方形面积的逻辑如下-

在运行时输入正方形的边。

area=(float)side*side;

用于查找圆面积的逻辑如下-

运行时输入圆的半径

area=(float)3.14159*radius*radius;

用于查找矩形区域的逻辑如下-

在运行时输入矩形的长度和宽度

area=(float)len*breadth;

用于查找平行四边形面积的逻辑如下-

输入平行四边形的底和高

area=(float)base*height;

示例

以下是使用switchcase计算三角形、正方形、圆形、矩形和多边形面积的C程序-

#include
#include
main(){
   int choice;
   printf("Enter\n1 to find area of Triangle\n2 for finding area of Square\n3 for finding area of Circle\n4 for finding area of Rectangle\n5 for Parallelogram\n");
   scanf("%d",&choice);
   switch(choice) {
      case 1: {
         int a,b,c;
         float s,area;
         printf("Enter sides of triangle\n");
         scanf("%d%d %d",&a,&b,&c);
         s=(float)(a+b+c)/2;
         area=(float)(sqrt(s*(s-a)*(s-b)*(s-c)));
         printf("Area of Triangle is %f\n",area);
         break;
      }
      case 2: {
         float side,area;
         printf("Enter Sides of Square\n");
         scanf("%f",&side);
         area=(float)side*side;
         printf("Area of Square is %f\n",area);
         break;
      }
      case 3: {
         float radius,area;
         printf("Enter Radius of Circle\n");
         scanf("%f",&radius);
         area=(float)3.14159*radius*radius;
         printf("Area of Circle %f\n",area);
         break;
      }
      case 4: {
         float len,breadth,area;
         printf("Enter Length and Breadth of Rectangle\n");
         scanf("%f %f",&len,&breadth);
         area=(float)len*breadth;
         printf("Area of Rectangle is %f\n",area);
         break;
      }
      case 5: {
         float base,height,area;
         printf("Enter base and height of Parallelogram\n");
         scanf("%f %f",&base,&height);
         area=(float)base*height;
         printf("Enter area of Parallelogram is %f\n",area);
         break;
      }
      default: {
         printf("Invalid Choice\n");
         break;
      }
   }
}

输出结果

执行上述程序时，它会产生以下输出-

When the above program is executed, it produces the following output:
Run 1:
1 to find area of Triangle
2 for finding area of Square
3 for finding area of Circle
4 for finding area of Rectangle
5 for Parallelogram
5
Enter base and height of Parallelogram
2 4 6 8
Enter area of Parallelogram is 8.000000
Run 2:
1 to find area of Triangle
2 for finding area of Square
3 for finding area of Circle
4 for finding area of Rectangle
5 for Parallelogram
3
Enter Radius of Circle
4.5
Area of Circle is 63.617199
