Debugging

Once a program has been written, it has to be tested first to ensure that it is free of errors. It is very normal that any program written will contain mistakes. When the source program is submitted to the compiler for conversion to object program, compiler identifies errors so that the same can be corrected. This process of checking and correcting errors is known as “Debugging”. The following steps are involved:

1.     Desk checking
2.     Compilation
3.     Testing with test data
4.     Running the program with actual data.
