1. LESSON 1 Introduction to Programming Language

2. Computer
Comprised of various devices that are referred to as HARDWARE.
The computer programs that run of a computer are referred to SOFTWARE.

3. Computer Program
Set of instructions used to operate a computer to perform specific task and produce result

4. Computer Programming
Writing computer program

5. Programming Language
Language used to create computer programs

6. Levels of Programming Languages
Machine Languages
Assembly Languages
High Languages

7. Machine Language Lowest level of computer languages
Only language that computer can understand.
Consist entirely of 1s and 0s.
Easily understood by computers but difficult to read by people.

8. Uses symbolic names and operands instead of 1s and Os
Assembly Language
Uses symbolic names and operands instead of 1s and Os
e.g. MOV and ADD
Needs ASSEMBLER to translate instruction to machine level language

9. High-Level Languages
English like language instructions so it is easier to learn, use and debug the program.
Example
FORTRAN, COBOL, BASIC, PASCAL, C, C++ and JAVA
It needs the help of COMPILER to be understood by the computer

10. What is Compiler
Translates the high level program(source code) into machine code(object code).
High Level Program
Compiler
Machine Code
0,1

11. History of C++
In 1970s, at Bell Laboratories, Dennis Ritchie and Brian Kernighan designed the C programming language.
Most of C is a subset of C++
C++ was developed by Dr. Bjarne Stroustrup in 1985 at AT&T Bell Labs New Jersey, USA.
Initially called as “C with classes” but was change to C++
