7 best online compilers 2024 for C, C++, Java, Python

A compiler, also known as compilation software, compiler, is a computer program that translates a series of statements written in a programming language (called source language or source code), into an equivalent program but in the form of a new computer language (called the target language ) and often a lower-level language, such as machine language. This newly compiled program calls object code (according to wikipedia).
