Q is random value, because your structure of p - & gt; Initialization NextPig field is not NULL

Thanks, excuse me how to modify things

If you are using c + +, in the class constructor, set the field is NULL.

Hello, is that in structure or in SortPigsByName this function? Sorry, just learn c + + and data structure, many of them still do not understand

CodePudding user response:

Your mistake is in createpig this function
Less in return before the head, one line of code
P - & gt; PNextPig=NULL;
As a result, although the

head back to the right, but the

tail
is not clear?
To

sorting before, the first group of

out bold show a circle
You can see the tail wrong
