OOCP (CPP)  :  Example # 02 : How to Set Precision in C++

* Lets start learning CPP (C++) Using Example.
* Program is about how to set precision in c++

//Written by Latest Technology Guide    
//Title : OOCP (CPP)  :  Example # 02 : How to Set Precision in C++

#include <iostream.h>

#include <iomanip.h>

#include <conio.h>

#define PI 3.1415

class area

{

private :

int r;

public :

void getdata()

{

cout << "Enter Value of R : ";

cin >> r;

cal_display();

}

private :

void cal_display()

{

float area;

area = PI * r * r;

cout << "Area of the Circle is : " << setprecision(4) << area;

}

};

void main()

{

clrscr();

area obj;

obj.getdata();

getch();

}

Output:

* By writing setprecision(4) precision will be set to 4.

* Simply change precision as per your requirement and run again.
