With all due respect, this kind of thing to do?CodePudding user response:
What's the problem? ! The code can be optimized.CodePudding user response:
Use timer is betterCodePudding user response:
Delay (50000); CPU card, basic can't do other, wasteCodePudding user response:
First of all, don't know what you want to ask what is the problem? Moreover, the program compilation should be no problem,Tip: delay in the program (50000); A bit of a waste of resources, _crol_ (), the delay () function if it is placed behind the main function need to declare, the main function in front of her is nothing
