C Code to calculate Area of Right Angle triangle and Circle

To calculate the are of a Right angle triangle , we use the below below formula area=(base*height)/2 and for Circle Area , we use the mathematical formula as area=3.14*radius*radius .

C Code for calculating the Area of Right angle triangle and Circle together using switch in C .

// Area of a Right angle Triangle and Circle
#include<stdio.h>
#include<conio.h>
int main()
{
int base , height , x;
float area,radius ;
clrscr() ;
printf("Enter A number given below to proceed");
printf("\n Enter 1 for 90 degree Triangle Area ") ;
printf("\n Enter 2 for Circle Area");
printf("\n");
scanf("%d",&x);
switch(x)
{
case 1 :
printf("Enter the base length and height of triangle")  ;
scanf("%d%d",&base,&height);
area=(base*height)/2 ;
printf("\n Area of this 90 degree triangle is = %f",area);
break ;

case 2 :
printf("Enter Radius of Circle");
scanf("%f",&radius);
area=3.14*radius*radius ;
printf("Area of Circle is = %f",area) ;
break ;

default :
printf("Enter a valid Input ... ") ;
}

getch();
return 0 ;
}
