Compiling, compiling flags from "summary" of C Programming Language First Edition ( Part 2) by ARPAN SAHA

Compiling is the process of translating source code written in a programming language into an executable program that can be run by computer systems. Compilation involves a set of flags which are used for controlling various compilation features like debugging, optimization etc.

When compiling programs one should pay attention to values associated with the compiling flag. These values affect the operation of the compiler and can have unintended consequences if not used properly.

An important concept when dealing with compiling flags is to understand what each flag does and its effects on the compiled program – how it will be executed and optimized.

Debugging flags help to print out messages at runtime or during compile time, allowing users to debug their programs more efficiently. Optimization flags are used to improve the performance and speed of the compiled program, but this comes with the cost of increased memory usage and other resources.

Knowing which flags are necessary to properly compile a program and understanding their effects are key skills to master as a programmer. Professional programmers need to acquire experience learning the best practices and techniques associated with effective compilation processes through trial and error.

It's also important to bear in mind that some versions of a specific compiler may use different set of flags than others - meaning that compatibility might be an issue while sharing programs across platforms.
