To debug a program, click on the Next line has no effect, a face of meng,
Then did an experiment, found that as long as write the string, can't do the Next line, let alone to check the content of the string, I this is where the problem, solving the

Not very know what you mean, I'm debugging here no problem, C - type and String can be seen

CodePudding user response:

I can't , add view STR results shown on the Debug STR
STR={
The static npos=& lt; Optimized out>
_M_dataplus={... }
_M_p=0 by 8 "error: always access the memory at address 0 by 8 & gt;

Just show the STR for these three lines, and the Next line, click no, if just write an a + b (int), everything is ok,,,

reference 4 floor huojinmeng response:

to GCC optimizations instead - o0

Thank you for your answer, could you speak more specifically? Don't understand, ha ha, there is string comparison experiment on the ground floor)
