The C compiler is not as strict with syntax checks as other high-level languages, which gives programming experts some “flexibility”. However, this flexibility brings many inconveniences to debugging, especially for those who are just starting to learn C. They often make errors that they themselves cannot identify. 1. Ignoring Case Sensitivity When Writing Identifiers. The … Read more
