1. Introduction to Programming
Languages
Sayed Mahmoud AbdEl-Rahman

2. What is the meaning of
Programming Language?
• Programming language is like any other
language around the world.
• English – Arabic – Spanish – French.

3. What’s in a language?
• Words.
• Grammars.
• Expressions & sentences.

4. Why do we need it?
Why learn a language?
• You might need to deal with programmers in
the course of your work.
• You may also be required to do some
programming yourself in the future.

5. Program & Programming
• What is a Program?
A program is a list of instructions for the
computer to follow to accomplish the task of
processing data into information.
• What is a programming?
programming is the act of writing (coding)
the program to process data.

6. What’s a 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.

7. Programming Languages Around
the worlds

8. Classification of Programming
languages
• High Level Languages
(C - C++ - C# - Java - VB)
• Low Level Languages
(Assembly – Machine Language)

9. How can a computer understand
these languages?
• 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 very
complex. The high-level languages (such as Basic, C,
Java) 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.

11. Which Language is the Best?
• No language is perfect or ideal than other
languages.
• No language has the best History.
• Every language has its place in programming
world!

12. How we would select a programming
language
• Compile vs. interpreted and assembly.
• Easy to use.
• Problem Domain.
• Security provision.

13. How to be a Programmer?
What to learn?
• Tools or Platform ( Visual studio).
• White Papers and Pen.
• Any Reference you Like (Love) it (only one).

14. What should been you know ?
• Syntax.
• Selection (If , Switch)
• Loops (For , While)
• Functions.
• Pointer , Arrays, References
• Classes, object
• File IO

15. How can write a code?
Input Processing Output
(Program)
1- Define the Problem (build the algorithm).
2- Design the Program.
3- Write the Code.
4- Debug the Program.
5- Test the Program.

16. Computer Branches
• Graphics & Images Processing.
• Programmer.
• Database.
• Controlling.
• Network.
• Operating System.
• Hardware.
