CodePudding user response:
There is an error in this sentence: the scanf (" % d % d % d ", & amp; A, & amp; B, & amp; C);//the scanf (" % d % d % d \ n ", & amp; A, & amp; B, & amp; C); CodePudding user response:
Why to add in front of the backslashCodePudding user response:
Added the \ n and useless, and still can't run
