Write a Program in C++ That Bar Chart Printing Program

// Bar chart printing program.

#include <iostream>

#include <iomanip>

#include <array>

using namespace std;

int main()

{

   const size_t arraySize = 11;

   array< unsigned int, arraySize > n = 

      { 0, 0, 0, 0, 0, 0, 1, 2, 4, 2, 1 };

   cout << "Grade distribution:" << endl;

   // for each element of array n, output a bar of the chart

   for ( size_t i = 0; i < n.size(); ++i ) 

   {

      // output bar labels ("0-9:", ..., "90-99:", "100:" )

      if ( 0 == i )

         cout << "  0-9: ";

      else if ( 10 == i )

         cout << "  100: ";

      else

         cout << i * 10 << "-" << ( i * 10 ) + 9 << ": ";

      // print bar of asterisks

      for ( unsigned int stars = 0; stars < n[ i ]; ++stars )

         cout << '*';

      cout << endl; // start a new line of output

   } // end outer for

} // end main
