Debugging
An error in a computer program is known as bug. The programmer can make different
errors while writing programs.
The process of finding and removing bugs is known as debugging.
Run Time Error
A type of error that occurs during
the execution of program is known as run-time error. It is caused when a
statement directs the computer to execute an illegal operation such as dividing
a number by zero.
The run-time errors are detected and
displayed by the computer during execution. Run-time errors are normally caused
due to wrong input from the user. The computer stops executing the program and
displays error message if a run-time error occurs.
Example:
The
user may ask the program to open a file that does not exist. Similarly, the
user may enter wrong type of data etc.
Logical Errors
A type of error that occurs due to poor logic of programmer
is known as logical error. A logical error occurs when the program follows a
faulty algorithm. A statement with logical error may produce unexpected and
wrong results. For example, the programmer may have written a wrong formula to
computer an answer. The formula will be executed without any error but will
produce wrong results.
