Compiler

• Compilers work by reading the whole source code and translating it into machine code, before the program is run or distributed to users.
• The result is an executable file which can be run directly by the CPU.

Positives of compilers

• Runs faster
• Can be optimized for specific hardware
• Can be shared without source code (e.g. proprietary software)
• Catches most errors before running

Negatives of compilers

• Compiliation takes time
• Not as easy to use a debugger
