Into To Solve Problem And Computer Programming
- 1. Into To Solve Problem And Computer Programming By : Ahmed Elnemr
- 2. SOLVE PROBLEM 1. Defining the problem . 2. Designing (Planning ) the solution . 3. Implementation the program . 4. Testing the program .
- 3. Defining the problem . The programmer must analyze the problem . consider all possible ways of solving it . EX : using a calculator to solve a mathematical problem .
- 4. Designing (Planning ) the solution the designing stage to solve any problem is the most important part of the solution . Two ways of planning the solution to a programming problem : 1 . Algorithm . 2 . Flow Chart .
- 5. Planning using algorithm Is step-by-step sequence of instructions and decision logic needed to solve a processing problem . Input Output Finite Effective Ex 1. Read Num1,Num2 2. sum = Num1 + Num2 3. sub = Num1 - Num2 4. Write sum and sub 5. Stop
- 6. Planning using Flow Chart Is simply a graphical representation of an algorithm . Is one way of diagramming the logic of a program . Start / End Read/write DecisionProcessing Direction (flow line)
- 8. Implementation (Coding) the Program programming language : ➢ Coded language used by programmers to write instructions that a computer can understand to do what the programmer (or the computer user) wants. ➢ The most basic (called low-level) computer language is the machine language that uses binary ('1' and '0') code which a computer can run (execute) very fast without using any translator or interpreter program, but is complex. ➢ The high-level languages (such as VB, C, C++, Java ,PHP ,JS) are much simpler (more 'English-like') to use but need to use another program (a compiler or an interpreter) to convert the high-level code into the machine code .

- 10. Desktop Applications A desktop application is a standalone application that is installed on a desktop or laptop computer. Usually, desktops apps are limited by the hardware and software they run on Ex : MS Office , Avira Antivirus, Inventory Apps, restaurant, Media, Editors, IDE, … etc.
- 11. How to Create Desktop App ? It all depends on the kind of desktop application that you want to make. If it is the kind of application that requires a lot of security, then you might opt for Java, C#, Python or C++. DBMS (Database Management System) as MySQL, MSSQL, Oracle Database, ..,etc.
