Instead of sounds as values, we represent sounds as “objects”—a programming structure that packages a collection of operations or “methods” with a collection of data values. In lazy evaluation systems, function arguments (i.e., sub-expressions) are not evaluated before passing them to functions . For example, we could construct a list containing f , f , …, f without ever applying function f.
High-level code uses words that are designed to be read by human programmers as well as a computer. Statements written in high-level languages such as Visual Basic, C++, Python, Delphi and Java are therefore understood far more easily than programs written in machine code or assembly language. Because machine code instructions are the only ones the CPU can execute, the source code for ALL other programming languages must be converted into machine code before it can be executed. This translation is carried out by special programs called compilers, … Read More
