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=0.5*b*h;

break;

}

printf("The area is : %f",area);

}
