CodePudding user response:
What's the problem? Or a simple code?CodePudding user response:
Your code is not complete, such as:struct Class * banjixinxi (struct Class * head)
{
int j;
for(j=1; j<=5; J++)
{
StuHead=chengjishuyu (j);
}
return head;
}
The head here doing nothing, return directly, except for some compilation errors in the program, is the code haven't finished writing, even if it were not for the error can not run, suggest the building finished ask
