What is Interpreter?

An interpreter is a Computer programmer that directly executes the statement written in the program without compiling it into a machine language (it does not convert it into a lower/machine-level language), interpreter reads each statement of the code & then directly executes the statement of the given source code.

What is Interpreter?<br/>

An interpreter is a Computer programmer that directly executes the statement written in the program without compiling it into a machine language (it does not convert it into a lower/machine-level language), interpreter reads each statement of the code & then directly executes the statement of the given source code.

When is Interpreter used? <br/>

The interpreter is used when we want to execute the program, interpreter transfers the source code into object code & immediately executes the program without translating or converting it into a machine-level language by this it takes less amount of time to analyze the source code & execute the program

Where is Interpreter used? <br/>

The interpreter is used in high-level programming languages such as python, javascript, and ruby. to execute the source code(i.e., written programming language) in a high-level language, the interpreter intermediate the code, processes it then executes the program

Who uses an Interpreter?

The interpreter is a computer program that directly executes the instructions that are written in a program or scripting language, it does not require them to convert into a machine-level language such as a compiler, it converts it into an intermediate language and then executes the program line by line.

Why is Interpreter used? <br/>

An interpreter is used because it does not require any intermediate code to generate, such as a compiler does, due to this it is highly memory efficient, the interpreter executes the source code them self only, so the code itself is the platform independent, & it usually takes less amount of time to analyze the source code, Interpreter is more efficient in memory allocation, more flexible, & offer features like dynamic typing & small program in size.

How does Interpreter works? <br/>

An interpreter translates the source code in some intermediate code one at a time, source code is compiled & kept as a machine-independent code, and it converts into an intermediate language line by line, For Ex: if we finish a statement in the first line & move to the second line interpreter first converts first line statement to intermediate code,(i.e, source code) the resulting code is executed immediately, this helps the programmer to find the error & correct them there itself in the first line only, rather going to the second line, by this it makes programmer extremely useful when developing programs.
