  5. Computer Programming A programming language is a communicate instructionsto a computer. Programming languages can be used to create programs that control the behaviour of a machine and/or to expressalgorithms precisely. Programming languages fall into two categories: Low Level Programming High Level Programming Programming In C++, Lecture 1

  6. Computer Programming Low Level Programming • Low-level languages are considered to be closer to computers. Its prime function is to operate, manage and manipulate the computing hardware and components. • Low Level Languages are: • Machine Languages • Assembly Languages Programming In C++, Lecture 1

  7. Computer Programming High Level Programming • Higher-level languages allow the programmer to work in a more English-like environment that resembles natural language or mathematical notation also visual environment, using graphical tools. • Procedural Programming • Object Oriented Programming Programming In C++, Lecture 1

  8. Computer Programming High Level Programming • Procedural Languages • A computer programming language that executes a set of commands in order is called procedural Language. It is written as a list of instructions, telling the computer, step-by-step, what to do. • For Example. • Open a file • Read a number • Multiply by 4 • Display something. • Procedural programming is fine for small projects. It is the most natural way to tell a computer what to do. Programming In C++, Lecture 1

  9. Computer Programming High Level Programming • Object Oriented Programming Programming In C++, Lecture 1

  10. Computer Programming High Level Programming • Web Development (HTML, PHP, JSP, ASP etc.) • Application Development (Java, C, C++, .net etc.) • Mobile Application (Objective C, J2ME etc.) • Data Base (SQL, SQL Plus) Programming In C++, Lecture 1

  11. Computer Programming Quiz • What is your Lecturer’s Name & his qualification? • Which Language is close to computer hardware? • What is Database language? • Which level of programming language is close to human? • Which programming language will you cover in this course? Programming In C++, Lecture 1

  12. What Is C Programming Language? Programming In C++, Lecture 1

  13. Introduction To C Programming Language Book “Turbo C Programming for PC and Turbo C++” By Robert Lafore, Programming In C++, Lecture 1

  14. Introduction To C Programming Language • The C programming language was designed by Dennis Ritchie at Bell Laboratories in the early 1970s • Traditionally used for systems programming, though this may be changing in favor of C++ • C Language in between the Low Level Language and High Level Language (Middle Level Language) Programming In C++, Lecture 1

  15. C Mainly Used For • Mainly because it produces code that runs nearly as fast as code written in assembly language. Some examples of the use of C might be: • Operating Systems • Language Compilers • Assemblers • Text Editors • Print Spoolers • Network Drivers • Modern Programs • Data Bases • Language Interpreters • Utilities Programming In C++, Lecture 1

  16. What We Need • PC Hardware • Ms-Dos • Turbo C Development System (Integrated Development System (IDE)) Programming In C++, Lecture 1

  17. Turbo C Development System • It is a screen display with windows and pull down menus. The program listing, its output, error messages and other information are displayed in separate windows. • You can use menu selections to invoke all the operations necessary to develop your program including editing, compiling, debugging, Linking and program execution. Programming In C++, Lecture 1

  18. Basics of C Environment • C systems consist of 3 parts • Environment • Language • C Standard Library • Development environment has 6 phases • Editing: Writing the source code by using some IDE or editor • Pre-processor: Already available routines • Compile:translates or converts source to object code for a specific platform • Link: resolves external references and produces the executable module • Load: load into memory • Execute : Run the program Programming In C++, Lecture 1

  19. Basics of C Environment • Compiling • Program are in two versions • You type which is called the source file. • Machine-Language version, which is called executable file The Complier, which is a part of the IDE, translates this source code into another file, consisting of machine language at once. The Interpreter, which is a part of the IDE, translates this source code into another file, consisting of machine language but line by line. Programming In C++, Lecture 1

  20. Basics of C Environment • Linking Execute new compiler-generated file to run your program. The Linker combines all the required files into a single executable file. Programming In C++, Lecture 1

  21. Basics of C Environment • Errors • Syntax Error • Logical Error Programming In C++, Lecture 1

  22. Files Used in C Program Development • Executable Files • Library & Runtime Files • Header Files • Programmer-Generated Files Programming In C++, Lecture 1

  23. Files Used in C Program Development Executable Files • Executable files are stored in the subdirectory BIN. The most important executable file for the Turbo C Language is the TC.EXE. • Executable this program places the IDE on your screen. • The BIN directory also contains programs for the command line development process. For example. • TCC Command-line compiler • TLINK Command-line linker • TCINST Customize Turbo IDE • CPP Pre-processor Utility • TLIB Library file manager • MAKE File management program Programming In C++, Lecture 1

  24. Files Used in C Program Development Library & Runtime Files • Various files are combined with your programs during linking. These files contain routines for a wide variety of purposes. • They are stored in LIB subdirectory. Programming In C++, Lecture 1

  25. Files Used in C Program Development Library Files • Library files are group of precompiled routines for performing specific tasks. • A library files has a unique characteristic: only those parts of it that are necessary will be linked to a program, not the whole file. Programming In C++, Lecture 1

  26. Files Used in C Program Development Header Files • The subdirectory called INCLUDE contains header files. • These files are text files, like the one you generate with a word processor or the Turbo C editor. Header files can be combined with your program before it is complied, in the same way that a programmer can insert a standard heading in a business letter. • Each header file has a “.h” file extension Programming In C++, Lecture 1

  27. Files Used in C Program Development Programmer-Generated Files • You can place the programs that you write in any subdirectory you choose:for instance a subdirectory under TC. Programming In C++, Lecture 1

  28. Introduction To C Programming Language Quiz • What we need to develop C programme? • What is difference between Complier & interpreter? • What is Linker? • What is source file & Executable file? • How many type or error could have? • What is Header files? • What is Library files?
