Set Precision in C++

In this article I would like to share with you a very short and simple program in C++ how to use set precision function in your C++ program. As a programmer using C++ there are some programming problems which deals with decimal values. One of the most interesting solution that I find is the use of C++ library file called iomanip or input / output manipulator. A standard library file in C++ that adds functionality in our program.

Our program will as the user to enter a number and then it will display the number with only two decimal places using the set precision function in C++. If you have some questions regarding about my work in C++ please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

      cout << "Set Precision Demo ";

      cout << "\n\n";

      cout << setw(20) << "Enter price : ";

      cin >> price;

      cout << setw(10) <<  "The price is " << price;
