Languages like Perl and PHP are called "interpreted languages" since the source code can be run through an interpreter without being compiled. Languages like C++ and Java are called "compiled languages" since the source code must first be compiled in order to run. Many high-level languages are similar enough that programmers can easily understand source code written in multiple languages.Įxamples of high-level languages include C++, Java, Perl, and PHP. Symbols like, =, and != are common operators. For example, reserved words like function, while, if, and else are used in most major programming languages. This allows programmers to write source code in a natural fashion, using logical words and symbols. High-level languages are designed to be easy to read and understand. Languages that programmers use to write code are called "high-level languages." This code can be compiled into a "low-level language," which is recognized directly by the computer hardware.

A programming language is a set of commands, instructions, and other syntax use to create a software program.
