Align columns/C++: Difference between revisions

A reusable template function that handles the tokenizing, and is independent of any work that might wish to be done with the results:

 

#include <string> // for getline etc.

#include <iostream>

}

}

 

A function object that fills an array with column widths:

 

 

struct MaxColWidthsDeterminer

else

m_colWidths[ nColIndex ] = max( m_colWidths[ nColIndex ], nWidth );

 

A function object that outputs fields formatted in columns:

 

{

enum Alignment { eLeft, eRight, eCenter };

 

m_nPrevColIndex = nColIndex;

 

The test program, that makes a pass through the data to determine the column widths, and then three more for outputting in each of the three column alignments:

 

{

const string strInput(

outFile << endl;

}
