[Newbie] Putting variables into an order

[Speedo]

If you are writing C++ (as opposed to plain C) you should prefer the sorting algorithms that are part of the STL. It really doesn't get much simpler than using them.

Example:

#include <algorithm>
#include <functional>
#include <iostream>

int main( )
{
  const int arraySize = 5;
  float data[arraySize] = { 5.0f, 2.34f, 0.932f, 10.0f, 8.213f };

  std::sort(data, data + arraySize, std::less<float>( ));
  std::cout << "Sorted least to greatest:" << std::endl;
  for (int i = 0; i < arraySize; ++i)
    std::cout << data[i] << std::endl;

  std::sort(data, data + arraySize, std::greater<float>( ));
  std::cout << "Sorted greatest to least:" << std::endl;
  for (int i = 0; i < arraySize; ++i)
    std::cout << data[i] << std::endl;

  return 0;
}
