Imperative

• Programs runs sequentially.
• Step-by-step instructions

Examples: Fortran, C

Functional

• Symbolic calculations

Examples: LISP, Haskell

Object Oriented

• Objects

Examples: Simula, Java, C#

Logic

• Prolog

Parallel

Evaluation criteria

There are three main criteria for evaluate a programming language. These are readability - writability, reliability, and cost.

Readability - Writability

• Basic constructs increase = readability decrease
• Feature multiplicity increase = readability decrease (multiple ways of doing the same thing)
• Operator overloading = readability increase
• Orthogonality = Orthogonality in a programming language refers to the property that language features can be combined freely
• Data types = readability increase

Reliabilty

• Type checking
• Exception handling

Cost

• Training: is it hard to teach language
• Development: is it hard to develop this language
• Cost of executing programs: Run time
