Question:
What is the operation in Breakpoint mode?

1.The program is interrupted after each detection

2.The program will not be stopped and the errors are sorted out after the complete program is scanned

3.There is no effect on the program, i.e the program is executed without rectification of errors

4.The program is halted only at specific points
