What is interpreter

An interpreter is a program that executes code written in a high-level programming language line-by-line. Interpreters are used to translate high level programming language into machine language (binary code).

As we know that a program written in high-level programming languages ​​like C++, Java, we call it source code, it first translates the first line of the source code, and if it finds any mistake in the first line , it shows an error and does not translate to the next line unless the error is completely rectified.
