Guidelines
Read messages on the course folder regularly
Start working on projects/assignments from first day.
Come prepared in the class
Read book (s)
Remain attentive during the class
Academic Honesty
All parties involved in any kind of cheating in any exam will get zero in that exam
Habitual cheaters will get zero in all assignments/projects. This may lead to a course failure
Cheating punishment may become more strict
Class Policies
Frequent quizzes will be taken during the semester.
Students are required to attend the classes regularly and come prepared in the class room.
Class assignments are required to be submitted on or before the due date and time. No marks will be given for the late submissions.
Programming assignments should be well documented.
It is highly recommended that you try to do the assignments on your own. Some questions from the assignments may be asked in the Exams
Class attendance policy of the University will be followed for taking the final test.
BCPL,C, C++
Martin Richards developed BCPL in 1967
A language for writing operating systems, software and compilers.
Ken Thompson modeled his language, B, after BCPL.
In 1970, Thompson used B to create early versions of the UNIX operating system
Dennis Ritchie evolved C from B at Bell Laboratories in 1973
Although C employs many important concepts of BCPL and B’s
C first gained widespread recognition as a development language of the UNIX operating system
However, C is now available for most computers, and many of today’s major operating systems are written in C or C++
C is a hardware-independent language, and, with careful design, it is possible to write C programs that are portable to most computers.
Visual BASIC
Developing Microsoft Windows-based applications in languages such as C and C++, Is difficult and cumbersome process.
When Bill Gates founded Microsoft Corporation, he implemented BASIC on several early personal computers.
BASIC is a programming language developed in the mid-1960s by Professors John Kemeny and Thomas Kurtz of Dartmouth College as a language for writing simple programs.
The natural evolution from BASIC to Visual Basic was introduced in 1991 as a result of the development of the Microsoft Windows graphical user interface (GUI) in the late 1980s and the early 1990s.
Java
Sun Microsystems in 1991 funded an internal corporate research project code-named Green.
The project resulted in the development of a language based on C and C++
James Gosling, called it Oak (after an oak tree outside his window at Sun),
It was later discovered that a computer language called Oak already existed.
When a group of Sun employees visited a local coffee place, the name Java was suggested
