Tips for Writing Computer Programs

When you’re ready to write a computer program, keep these how-to tips on programming in mind so the program you create has clear instructions for the computer to carry out tasks effectively:



  • Use descriptive variable names.



  • Use appropriate data types.



  • Write programs that are easy to read and understand.



  • Use simple algorithms and data structures whenever possible.



  • Comment your program liberally. (Or, as an alternative, make your code so clear and easy to read that you don’t need comments in the first place.)



  • Write modular programs by dividing a large program into several smaller programs that you isolate from one another.



  • Test boundary conditions by giving your program extremely high and extremely low numbers.



  • Choose the right algorithm and data structure for your program.



  • Eliminate all unnecessary instructions or variables.



  • Make your program work first; then worry about optimizing the program to make it smaller and faster. Remember that a slow, bloated program that works is preferable to a small, fast program that doesn’t work.
