Software approach, Top down design

One way of coding is to simply have a rough idea of what you want to do and then start typing a way to produce one huge source file.

This is a very bad idea.

The resulting code is likely to have many issues with it that include

• Poorly documented code, so very hard to maintain and update
• 'Spaghetti code' - which means a tangled mess of jumps and loops all over the code, very hard for someone to understand. Even by the original coder a few days later!
• Duplication of code, so wasting memory and running speed
• Very hard to develop by more than one person as there is only one file
• Very hard to debug - the file either works or it doesn't

Here are more issues, but hopefully the list shows that it is best to have a methodical, professional approach to coding which this mini-web will cover
