2
Q

A
testing a program line by line
3

what is defensive programming
A
- performing validation/sanitising
- writing a roust code
- testing for all possibilities
3

4
Q
what are run time errors
A
errors that occur during the program bc of a specific issue like no more memory left

fixes the errors found
