IT 104 1.3 Programming Languages:  An Overview One of the most important aspects of  programming is problem solving. The objective of problem solving in  programming is to develop a step-by-step  process logic that solves the problem. After the logic is developed, instructions are  written to implement the logic.  Computer programs are written in programming  languages that use a restricted vocabulary and  a structured syntax a computer

IT 104 1.4 History of Programming Languages   The first of the major languages, developed in 1957, was called FORTRAN (scientific computing). In 1958 LISP was developed (Artificial  Intelligence) The next development in this field happened when a committee for scientific research created  the Algol language. Algol is the precursor to languages such as Pascal, C, C++, and Java

IT 104 1.5 In the late 1970s and early 1980s, a new programming method known as Object  Oriented Programming, or OOP, was  developed. Languages such as  C and C+ are  OOP-based languages. Newer languages include Java, Visual C++,  and Visual Basic History of Programming Languages  (cont.)

IT 104 1.8 Compiled and Interpreted Languages Compiled  languages use compilers that translate  the entire programs into machine-level (binary)  language before an attempt is made to execute  them Examples of compiled languages: C, C++, and
