When debugging a C program on Code::Blocks 20.03, I press SHIFT F7 to step into the program, then I begin pressing F7 to go to the next line and watch variables changing in "real time".

But Code::Blocks 20.03's debugger won't enter any functions beside main, making it pretty useless, or forcing me to not use any function besides main (a bad programming practice).

How can I make Code::Blocks 20.03's debugger enter the functions too?

CodePudding user response：

1. Set a breakpoint (red circle) exactly on the line the function main is defined;
2. Instead of pressing F8 (the same as clicking Debug->Start/Continue), which would make the program just run until the last line and exit (only flashing on the screen before disappearing), press Shift F7 (the same as clicking Debug->Step Into), in order to make the debugger enter the function and not just run it completely and return its result;
3. Press F7 (the same as clicking Debug->Next line) to keep watching the program run "step-by-step";
4. When any other function is called, and the debugger is on that line (yellow arrow), you may enter that other function too, by repeating step 2.

Source Line Stepping

Once paused, you can continue execution:

• Debug->Start/Continue runs the program until the next breakpoint.
• Debug->next line runs the program until the next source line. If the current source line contains a function call, it will “step over” the function call.
• Debug->Step into will “step into” a function call, and pause at the next source line.
• Debug->Step out will continue program execution until the function call returns to its caller.
• Debug->Next instruction and Debug->Step into instruction are assembly debugging commands, and should not be used within the CodeBlocks IDE. Instead, the corresponding commands in the ADT should be used.
