1. IXA 1234 : C++ PROGRAMMING CHAPTER 1

2. PROGRAMMING LANGUAGE Programming language is a computer program that can solve certain problem / task Keyword: Computer program Solve problem Example of programming language: C++ Java

3. PROGRAMMING APPROACH Structured approach: problem is divide into sub problems and then solution is obtained. Solution to all sub problem is combined to solve the overall problem Object-oriented approach: identify the component (object), determine how the object interact with one another.

4. EVOLUTION OF PROGRAMMING Machine Language Sequence of 0 and 1 (binary code) Assembly Language Middle level language Understand by human High Level Language Eg: java, C++

5. LANGUAGE TRANSLATOR Language translator is a program which translates programs from source language into an equivalent program in an object language There are 3 type of language translator involved in programming language Interpreter Compiler Assembler

6. LANGUAGE TRANSLATOR COMPILER : A program that translates source code into object code.

7. LANGUAGE TRANSLATOR INTERPRETER An interpreter translates high-level instructions into an immediate form, which it then executes.

8. LANGUAGE TRANSLATOR ASSEMBLER A program that translates programs from assembly language to machine language Example: Intel-----MASM Motorola ------- 68000

9. PROGRAMMING LIFE CYCLE Program Analysis Program Modeling Program Coding Program Testing and Debugging Maintenance Documentation

10. PROGRAM ANALYSIS Clearly define problem Understand what the system must do Understand the final output of a system

11. PROGRAM MODELING Solution developed using model Three type of modeling: Algorithm :A formula or set of steps for solving a particular problem Pseudo code: An outline of a program, written in a form that can easily be converted into real programming statements Flowchart : Graphical representation of a process, depicting inputs, outputs and unit of activity

12. PROGRAM MODELING Program control structure: Sequence While If-then-else Repeat – until For case.

13. PROGRAM CODING Write complete program out in programming language such as c++ Write program compile program run program debug program repeat the whole process.

14. PROGRAM TESTING AND DEBUGGING Compile the program to detect error Debug is to find the error and fix it After get 0 error and 0 warning then the program can executed. Run / execute is a same meaning

15. PROGRAM MAINTENANCE After all the program compile and run successfully, the program should be maintained. Any enhancement to the system can be done after the implementation phase

16. DOCUMENTATION Documentation is very important in order to enhance system. Every time report must be completed and get approval.
