Best C Programming Solution

Language: - Itis the media of communication. Cis the Languageof programs & functions developed by Dennis Ritchie in 1972- 73 & in AT & T Bell Laboratories in USA. Programs: - Itis a group of statement which are executed step by step to performa desire task. Programs arethe instructions given to the system. Instruction: - A single order given to the systemis called Instruction. Software: - Itis a group of programs working with coordination with each other to get the desired result. Software is of two types: - 1. SystemSoftware: - like operating system(window) 2. ApplicationSoftware: - like MS Office, Adobe Reader and Anti-Virus. Language is of two types: - 1. Low Level Language: - Which is also called Machine language. E.g.: - C,C++ 2. High Level Language: - Which is used in simple English Language. E.g.: - HTML, PHP, Java and DotNet. C is also called Middle Level Language becauseit is flexible & compatible with machine as like Low Level Languageor use friendly as like high level language. Translators: - These are the software’s which converthigh level language or vice versa. There are 2 types of Translators. 1. Compiler
