The last time i we have discussed computer and its applications. Now we will go ahead that how computer were made and how far it has been. The computer machine was not a new concept actually way back centuries Indian and Chines used their own devices like computer as Abacus 🧮 (2700 BC) and Vedic mathematics which will compute complex calculations. later around 1800 there were many machines were invented like Pascal's Calculator (1652) Stepped Reckoner (1694) Arithmometer (1820) Comptometer (1887) and Comptograph (1889) The Difference Engine (1822) Analytical Engine (1834) The Millionaire (1893). later

History of C programming language
C programming language was developed to overcome the difficulties found in older programming languages such as BCPL, BASIC, B etc.
Definition C language
A compiler is a computer program that transforms human readable (programming language) source code into another computer language (binary) code. In simple terms Compiler takes the code that you write and turned in to the binary code that computer can understand. C compiler is a software application that transforms human readable C program code to machine readable code. The process of transforming the code from High Level Language to Machine Level Language is called “Compilation”. Human readable code is the C program that consists of digits letters, special symbols etc which is understand by human beings. On the other hand, machine language is dependent on processor and processor understands zeroes and ones (binary) only. All C program execution is based on processor which is available in the CPU; that is why entire C source code needs to be converted to binary system by the compiler. This tutorial is written for Windows, Unix / Linux and MAC users. All code has been tested and it works correctly on all three operating systems.

History of C++ programming language
C++ is a multi-paradigm programming language that supports object-oriented programming (OOP), created by BJarne Stroustrup in 1983 at Bell Labs, C++ is an extension(superset) of C programming and the programs written in C language can run in C++ compilers.
Definition C++ language
C++ development actually began in 1979, four years before its release, and it did not start out with the name C++; Its first name was C with classes. In the late part of 1983, C with Classes was first used for AT&T’s internal programming needs. Its name was changed to C++ later in the same year. C++ was not released commercially until the late part of 1985. C++ implements data abstraction using a concept called classes, along with other features to allow object-oriented programming and is considered a high level language. Classes help programmers with the organization of their code. They can also be beneficial in helping programmers to avoid mistakes. The original C++ compiler, called Cfront, was written in the C++ programming language. C++ compilation is considered efficient and fast. Its speed can be attributed to its high-level features in conjunction with its low-level components. When compared to other computer programming languages, C++ can be viewed as quite short. This is due to the fact that C++ leans towards the use of special characters instead of keywords.
