What a great god help have a look at what point is wrong.-CodePudding

CodePudding user response:

Struct studeng stud [n]. There are problems, n is a random value, not sure size; C language does not support the uncertain array length;
Can consider to use to implement the dynamic application space way:

 struct studeng * stud=NULL;

Behind the scanf added statements for space:

 
Stud=(struct student *) malloc (sizeof (struct student)); 
if (! Stud) 
exit(0);

After facing the stud can be in the form of an array to access and manipulate;

When the last note shall not apply to the stud, remember to free (stud); Release;

With this, the above that there is a problem, forget to take the n, after the n is the input of n;
