Set a breakpoint on the line of code where you want to trace the execution of the program. Click on the empty space to the left of the line of code and a red circle will appear indicating that a breakpoint has been set. When program execution reaches this line, the debugger will pause execution.

  • F10 (single-step entry): Enter the function call and execute the function.
  • F7 (Single step skip): Do not execute function calls, but skip them.
  • F8 (Continue): Continue executing the program until the next breakpoint is encountered or the program ends.

4. View variable values

You can view the values ​​of all variables in the current execution context through the "Variables" tab. This tab is located in the lower right corner of the code window. You can expand a variable to view its contents, or right-click the variable and select Evaluate Expression to view its value.
