C++ program to find area of Triangle, Circle and Rectangle – Computer Practical

In this practical we will write a c++ code to find the area of a triangle, circle or rectangle using function overloading.

C++ program to find area of Tiangle, Circle or Rectangle

#include<iostream.h>
#include<conio.h>

const float pi=3.14;
float area(float n,float b,float h)
{
    float ar;
    ar=n*b*h;
    return ar;
}
float area(float r)
{
    float ar;
    ar=pi*r*r;
    return ar;
}
float area(float l,float b)
{
    float ar;
    ar=l*b;
    return ar;
}
void main()
{
    float b,h,r,l;
    float result;
    clrscr();
    cout<<“nEnter the Base & Hieght of Triangle: n”;
    cin>>b>>h;
    result=area(0.5,b,h);
    cout<<“nArea of Triangle: “<<result<<endl;
    cout<<“nEnter the Radius of Circle: n”;
    cin>>r;
    result=area(r);
    cout<<“nArea of Circle: “<<result<<endl;
    cout<<“nEnter the Length & Bredth of Rectangle: n”;
    cin>>l>>b;
    result=area(l,b);
    cout<<“nArea of Rectangle: “<<result<<endl;
    getch();
}
