Setting the Width for Numbers

5 February, 2015 - 11:20

Setting the width for integer family and floating-point family data types must be done for the output of each value. Assume in the following example that age is an integer data type and money is a floating-point data type.

cout «  setw(4) «  age «  endl; cout «  setw(8) «  money «  endl;

#include<iomanip>  // needed for the setw
