- 7. 7 Introduction to Typesof Computer Language • The computer language is defined as code or syntax which is used to write programs or any specific applications. It is used to communicate with computers. • Broadly the computer language can be classified into three categories:- Machine language, Assembly language, and High-level language.
- 9. Machine Languages 9 • Itis the only language the computer understands. • It is made of 0s and 1s. • They must be in 0s and 1s because the internal circuit of a computer is made up of switches, transistors, and other electronic devices that can be either on or off (1 or 0 respectively). Example of Machine Language: (on page167) 1 00000000 00000100 0000000000000000 2 01011110 00001100 11000010 0000000000000010 3 11101111 00010110 0000000000000101
- 10. 10 Assembly Language • AssemblyLanguage is a low-level programming language. • Assembly language is designed to understand the instruction and provide it to machine language for further processing. • In computers, there is an assembler that helps in converting the assembly code into machine code executable. Eg. ASPER (ASsembler for PERipheral Processor Units of Control Data Corporation computer systems pre-COMPASS), BAL (Basic AssembLer) - for IBM System/360 and later mainframe systems
- 11. High-Level Languages • Developedto improve programmer efficiency from symbolic languages & to change focus from the computer to the problem being solved • They’re portable to different computers • They still need to be converted to machine languages in a process called compilation • Examples include: • BASIC • COBOL • Pascal • Ada • C • C++ • Java • Python
- 12. 12 Introduction to C •C programming is a general-purpose, procedural, imperative computer programming language. • Developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system. • C is the most widely used computer language.
- 13. 13 Why to LearnC Programming? • Easy to learn • Structured language • It produces efficient programs • It can handle low-level activities • It can be compiled on a variety of computer platforms
- 14. 14 Facts about C •C was invented to write an operating system called UNIX. • C is a successor of B language which was introduced around the early 1970s. • The language was formalized in 1988 by the American National Standard Institute (ANSI). • The UNIX OS was totally written in C. • Today C is the most widely used and popular System Programming Language. • Most of the state-of-the-art software have been implemented using C.

- 16. 16 Applications of CProgramming C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language. Some examples of the use of C are – • Operating Systems • Language Compilers • Assemblers • Text Editors • Print Spoolers • Network Drivers • Modern Programs • Databases • Language Interpreters • Utilities
- 17. 17 History of C Theroot of all modern languages is ALGOL, introduced in the early 1960s. ALGOL was the first computer language to use a block structure. In 1967, Martin Richards developed a language called BCPL (Basic Combined Programming Language) primarily for writing system software. In 1970, Ken Thompson created a language ‘B’ using BPCL to create early versions of UNIX operating system. C evolved from ALGOL, BPCL and B. It uses many concepts from these languages and added the concept of data types and other powerful features
