As we all know computer is just a machine and it does not understand our language, but there would be something for Computer?? Well it's binary Language, which computer uses for it's different purposes. So if we need to ask computer something ,it should be in the language which computer can understand. Which is Binary Language.But we are humans who can we speak or write binary???

For this purposes software like C++ are made , which convert our Language into Binary Language and work as a medium between Humans and Computer.C++ use compiler for doing this.

In short Computer do not understand our language, it uses Binary Language. And C++ is the program which convert our Language into Binary Language.

What is C++ Compiler?

It is nothing just a computer program , whose job is to covert the C++ program from our form to the form which Computer can read and than think over it ( Execute ).

The original C++ program written is called the "source code" and the resulting code after compilation is called " object file "


Before compilation takes place  the preprocessor performs preliminary operations on C++ source files. When preprocessor does it's work the new form of source code ( preprocessed ) is sent to the compiler.


When compilation is completed the object files are combined with predefined libraries by a binder commonly known as Linker, to produce the final complete file which can be executed by the computer.

Library - A library is a collection of pre-compiled “object code” that provides operations that are done repeatedly by many computer programs.

Well, I am Vivek singh... I'm perusing my 12th from Saint Francis Senior Secondary School,Hathras......Next month i am going to have Board Exams...I thought many students are there who find difficulty in Computer Science. So i decided to make this site, it could be useful to you and even to me as my revision is going on by writing all this stuff for you..Now check the C++ from starting  :)
