working three lines at a time, converting to machine code, checking syntax and executing the code.
A compiler is a translator that converts high level programming languages into machine code. It does this by...
working through the whole program (source code), checking the syntax, then converting to machine code and creating an object. The object code is executed not the source code.

an error in the format of the program statements such as missing keywords.
an error in the format of the program statements such as missing semi-colons or keywords spelt incorrectly.
an error in the punctuation of program statements.
Logic errors in programs are...

errors in the algorithm that means the outcome is expected, even though the program will run.
errors in the algorithm that means the outcome is unexpected, even though the program will run.
errors in the algorithm that means the outcome returns nothing as the program will not run.
