In C++ write a program that prints out PI as a type double and a type float EXACTLY as shown below. Your program should have ONE cout statement within a loop which alters the width and precision each time through the loop. Do not write 10 separate cout statements for this problem. Show the output in a table that increases the precision from 1 to 10 as shown below. Use dash ('-') as the fill character. Note the differences as the precision gets larger.

Use the following two variables for PI.

double PI_D = 3.14159256359;
float PI_F = 3.14159256359;

Answer:

#include<iostream>

#include<iomanip>

using namespace std;

int main()

{

double PI_D = 3.14159256359;

float PI_F = 3.14159256359;

cout<<"i"<<"\t\t"<<"Float"<<"\t\t"<<"Double"<<endl;

for(int i = 1; i<=10;i++)

{

 cout<<i<<"-\t\t"<<PI_F<<setprecision(i)<<"-\t\t"<<PI_D<<setprecision(i)<<endl;

}

 return 0;

}
