3. Similarities
A Compiler and Interpreter both carry out the same purpose
Translates a high level language (like C++, Java) instructions into the binary form which is understandable by computer hardware (Machine language).
Compiler
Interpreter

4. Differences An interpreter A Compiler
Reads one statement then translates it and executes it and then takes another.
Easy to check for mistake(debug) than a compiler
Programme instructions are performed slowly
A Compiler
Translates the entire program in one go and then executes it (.exe file).
Hard to spot and correct mistakes
Cannot make changes once executable programme is created.
Programme instructions are performed quickly

5. Uses
An interpreter is used for program development as it is easier to debug and partially test the code.
Once the program is error free and complete, the program should then be compiled, as compiling only needs to be done once.
