Debugging Your Code

• Check your syntax:
  • Are you missing a semicolon?
  • Do you have a semicolon where its not needed? (at the end of an if statement: if(..);)
• Variables:
  • Have you defined the variable
  • Have you defined the same variable twice?
  • Have you spelled your variables wrong?
• Include Files: Have you included all the necessary files using #include <..>
• printf:
  • Does the number of format specifiers (%f, %c, etc.,.) match the number of variables?
• Are you using an assignment operator ( = ) in the place of a comparison operator (== )
