a program to calculate area of a circle,rectangle & triangle depending upon users choice.

Question

using switch and without string

Answer 1

#include<iostream>
using namespace std;
int area (int);
int area (int, int);
float area (float );
float area (float ,float );
int main ()
{
int s,l,b;
float r,bs,ht;
cout << "Enter side of a square:" ;
cin>>s;
cout << "Enter length and breadth of rectangle : ";
cin>>l>>b;
cout << "Enter radius of circle :" ;
cin>>r;
cout << "Enter base and height of triangle : ";
cin>>bs>>ht;
cout << "Area of square is" << area (s);
cout << "\nArea of rectangle is " << area(l,b)
cout << "\nArea of circle is " << area(r);
cout << "\nArea of triangle is " << area(bs,ht);
return 0;
}
int area (int s)
{
return (s*s);
}
int area (int l, int b)
{
return (l*b);
}
float area (float r)
{
return (3.14 *r*r);
}
float area (float bs, float ht)
{
return((bs*ht)/ 2);
}
