CodePudding user response:

There is a problem here: the scanf (" % s ", & amp; Stu [I] num); To the scanf (" % s ", stu [I] num);
Stu [n]. Num=malloc (10 * sizeof (char)); This is an error? A void * should be cast

CodePudding user response:

And the next post code, get format, otherwise a lot of people don't see

Discuss the
order to below,

 
Printf (" please enter the number of students: \ n "); 
The scanf (" % d ", & amp; The current); 

For (n=0; nStu [n]. Num=malloc (10 * sizeof (char)); 
Stu [n]. Nam=malloc (5 * sizeof (char)); 
}

Well, under the name here also change
Remove & amp;

 
Printf (" please enter the student's student id: \ n "); 
The scanf (" % s ", stu [I] num); 

Printf (" please enter the student's name: \ n "); 
The scanf (" % s ", stu [I]. Nam);
