    Do you know about the opcode set of your target machine? Everything that isn't doable with a fixed string of opcodes from that set will require a loop no matter how great a programmer does it. It makes no sense to be worried about "using loops" because they might be slow. Commented Mar 7, 2016 at 14:39
  • If I'm writing something in .NET, there are functions that are available to me for string manipulation, data type conversion, etc. Commented Mar 7, 2016 at 14:39
  • @JMcD those would be part of the standard library (not so much 'built in'). I would encourage you to read through, say... the String class on Java (part of its standard library) and count the loops. Commented Mar 7, 2016 at 14:46
