This is an algorithmic language similar to C, Fortran, and Pascal but with a stronger focus on multimedia. Thus, cT includes increased support for color graphics, mouse interactions, and video. It was a good alternative for developing multimedia programs across different platforms, but it was pushed aside in favor of VPython. 

C (, as in the letter c) is a general-purpose, procedural computer programming language supporting structured programming, lexical variable scope, and recursion, with a static type system. By design, C provides constructs that map efficiently to typical machine instructions.
