Structured programming practices(71)rise to Pascal，in which constructs were introduced to make programs more readable and better(72). C provided a combination of assembly language and high-level Structure to create a general-purpose language that could be used from system to(73)programming. Next came object orientation，which is(74)of a methodology and design philosophy than a language issue．This is(75)by the addition of so-called OO extensions to current languages，such as C．
