This paper is all about to do the basic study of the programming language. It is very necessary to have basic ideas of the languages i.e C, C++ and JAVA to learn new innovative technologies. The C language was introduced in 1970s to make a program on the computer which can be run very easily. This need led Ritchie to develop the programming language called C[2]. Later on the speed to work changed and people want everything to get their work faster and hence C++ language was introduced which literally means increment of C by 1[1]. The purpose of C++ is to make writing good programs easier and more pleasant for the individual programmer. But the problem was that the program was unable to run on other system and was not more secure and hence a language called Java was introduced to implement a virtual machine with programming language to support platform independency, secure, and fast. In this paper we are going to have detail study about the computer languages which are essential for the computer engineer to make the program logic easy to implement.
