Therefore, how to effectively control the execution of the statements in the program, so that when the appropriate time to pause, the debugger to display or set the value of some of the storage unit and then continue from where to stop, is the debugger should have a basic function. In this section we will specifically describe how to control the operation of the program. The first problem with program execution control is to set breakpoints. A breakpoint ...
