How to display a 0 after a decimal

Question

If I want to show a dollar amount like $1.50, how do I get the 0 to display?

Answer 1

When I use float, the 0 in the hundreths place does not display. Do I need to use double?

Answer 2

Here's an example:
#include<iostream>
#include <iomanip>

using namespace std;
int main()
{
float a=111.5;
float b= 2.333333;
cout << fixed << setprecision(2);
cout << "Your a= " <<a;
cout << "Your b= " <<b;
return 0;
}

You have to include this line at the beginning of your code:
cout << fixed << setprecision(2);
And don't forget to include iomanip library! :)

Answer 3
