> Example, the first abstraction is to use functions, if/else, and loops instead of plain goto everywhere like the CPU like. CPU likes if/else and loops just as much as it like its gotos. If/else and loops are just conditional jump (with a comparison done before the jump), and gotos are uncoditional jumps. Both are very much machine code constructs, that's why they're in C (which is basically a syntactic sugar over assembly). Function calls are slightly more involved, but basically also very, very low level.
