This document discusses programming languages and the program development cycle. It describes machine language as the fundamental language of the computer's processor using 0s and 1s, assembly language as a low level language similar to machine language, and high level languages like C++ and Visual Basic that use English-like statements. It also outlines the 7 steps of the program development cycle as analyzing the problem, designing a solution, choosing interfaces, coding the algorithm, debugging and testing, and completing documentation. Finally, it lists flowcharts, pseudocode, and hierarchy charts as common programming tools.

- 2. 2 Outline and Objective Program Development Cycle Programming Tools
- 3. 3 Programming Languages: • Machine Language • Assembly Language • High level Language
- 4. 4 Machine Language • The fundamental language of the computer’s processor, also called Low Level Language. • All programs are converted into machine language before they can be executed. • Consists of combination of 0’s and 1’s that represent high and low electrical voltage.
- 5. 5 Assembly Language • A low level language that is similar to machine language. • Uses symbolic operation code to represent the machine operation code.
- 6. 6 High Level Language • Computer (programming) languages that are easier to learn. • Uses English like statements. • Examples are C ++, Visual Basic, Pascal, Fortran and …....
- 7. 7 Program Development Cycle: 1. Analyze: Define the problem 2. Design: Plan the solution to the problem 3. Choose the Interface: Select the objects
- 8. 8 Program Development Cycle: 4. Code: Translate the algorithm into a programming language. 5. Debug and Test: Locate and remove any errors in the program. 6. Complete the Documentation: Organize all the materials that describe the program.
- 9. 9 Programming Tools: • Flowchart • Pseudocode • Hierarchy Chart (Structure chart)
