The Big picture

• Compiler is part of program development environment
• The other typical components of this environment are editor, assembler, linker, loader, debugger, profiler etc.
• The compiler (and all other tools) must support each other for easy program development

All development systems are essentially a combination of many tools. For compiler, the other tools are debugger, assembler, linker, loader, profiler, editor etc. If these tools have support for each other than the program development becomes a lot easier.

This is how the various tools work in coordination to make programming easier and better. They all have a specific task to accomplish in the process, from writing a code to compiling it and running/debugging it. If debugged then do manual correction in the code if needed, after getting debugging results. It is the combined contribution of these tools that makes programming a lot easier and efficient.
