- Compile multiple source files into an executable:

`gcc {{path/to/source1.c path/to/source2.c ...}} -o {{path/to/output_executable}}`

- Show common warnings, debug symbols in output, and optimize without affecting debugging:

`gcc {{path/to/source.c}} -Wall -g -Og -o {{path/to/output_executable}}`

- Include libraries from a different path:

`gcc {{path/to/source.c}} -o {{path/to/output_executable}} -I{{path/to/header}} -L{{path/to/library}} -l{{library_name}}`

- Compile source code into Assembler instructions:

`gcc -S {{path/to/source.c}}`

- Compile source code into an object file without linking:

`gcc -c {{path/to/source.c}}`

- Optimize the compiled program for performance:

`gcc {{path/to/source.c}} -O{{1|2|3|fast}} -o {{path/to/output_executable}}`
