C Conditional Statement: Exercise-25 with Solution

Write a program in C which is a Menu-Driven Program to compute the area of the various geometrical shape.

Pictorial Presentation:

A menu-driven program to compute the area of the various geometrical shape

Sample Solution:

C Code:

#include <stdio.h>
void main ()
{
      int choice,r,l,w,b,h;
      float area;
      printf("Input 1 for area of circle\n");
      printf("Input 2 for area of rectangle\n");
      printf("Input 3 for area of triangle\n");
      printf("Input your choice : ");
      scanf("%d",&choice);
      switch(choice)
      {
           case 1:
                 printf("Input radious of the circle : ");
                 scanf("%d",&r);
                 area=3.14*r*r;
                 break;
            case 2:
                  printf("Input length and width of the rectangle : ");
                  scanf("%d%d",&l,&w);
                  area=l*w;
                  break;
            case 3:
                  printf("Input the base and hight of the triangle :");
                  scanf("%d%d",&b,&h);
                  area=.5*b*h;
                  break;
          }
          printf("The area is : %f\n",area);
}

Sample Output:

Input 1 for area of circle                                                                                    
Input 2 for area of rectangle                                                                                 
Input 3 for area of triangle                                                                                  
Input your choice : 1                                                                                         
Input radious of the circle : 5                                                                               
The area is : 78.500000
