What is Debug
Program errors are called
Bugs in the programming world. Removing process of these Bugs are called
Debug. A programmer can commit two kinds of error while writing the program. These are:
- Syntax Error :
When a command written by the programmer is not matched with the Grammar of the concerned Programming Language, there occurs Syntax Error. Compiler or Interpreter can find this kind of Bug very easily so debugging of these are very easy.
- Logical Error :
Logical Errors are self explanatory. When there is a conceptual error occurred then this kind of bug arise. We can't get the expected result from the program when there is Logical Error. This kind of errors are very hard to find and debug. Every step of the program should be very carefully examined while debugging Logical Error.
Let's think of a situation. A program wants to calculate the result of 10 * 2 + 5. If 10*2*5 is written on the program, compiler or interpreter does not show any error as this is grammatically correct. But the result does not match with our calculation. If the program consists 500 lines, we have to examine all the 500 lines very carefully to debug the problem.
What is User Interface
The picture that is seen by the user of the program is called the User Interface of that program. User uses this user interface to run the program. If there is graphics in the User Interface then that is called "
Graphical
User
Interface" or
GUI.
What is Reserve Word
Every Programming Language has its some own words that are used to serve some fixed special purpose. These words are called
Reserve Words or
Keywords. Example of Visual Basic's some Reserve Words are:
True,
False,
WithEvents,
If etc.
