C Problem Solving

This lesson is part of C · All levels

Summary

Problem solving in C is the skill of breaking down big problems into small log steps before writing code. The flow is generally understanding the problem, crafting pseudocodes, implementing them, testing them, then fixing them. Routine practice on the little things builds up a mindset that makes the difficult issues feel more measurable.

Key points

Understand the problem by identifying the input, output, and limitations that apply.
Set up a pseudocode or algorithm plan before opening the editor.
Do a dry run by tracking the value of the variable manually in some cases including the edge case.
Debug systematically by minimizing the problem area and testing one by one.
Refine the code after the program runs, for example, fix the variable name and break down the long function.
