In this, we are going to see how to find Area of Circle using C++ program.
The formula to calculate is,
Area of Circle = π * radius * radiusÂ
The Code given below can be used in Turbo C++ Compiler.
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
float area, radius, pi=3.142;
cout<<"This program is for Area of circle\n";
cout<<"Enter the radius of the circle\n";
cin>>radius;
//formula for area of circle is π x radius^2
area = pi*radius*radius;
cout<<"The Area of the circle with radius "<<radius<<" is = "<<area<<" sq units";
getch();
}
The Code given below can be used in g++/gcc Compiler.
#include<iostream>
using namespace std;
int main()
{
float area, radius, pi=3.142;
cout<<"This program is for Area of circle\n";
cout<<"Enter the radius of the circle\n";
cin>>radius;
//formula for area of circle is π x radius^2
area = pi*radius*radius;
cout<<"The Area of the circle with radius "<<radius<<" is = "<<area<<" sq units";
return 0;
}
