Print function output not to come out something

CodePudding user response:

Don't know where is wrong

CodePudding user response:

About when you perform input function input format is wrong, so that the scanf failed,

CodePudding user response:

The teacher should be defined as a character array, see using the % s in the input function, if still use character, so the % s will lead to cross here, because the % s to receive characters, at least 2 characters, because also account for a character '\ 0',

In the same way with % s output in the print the teacher

So, it is recommended that the original poster to define the teacher as a character array, such as char the teacher [32].

Define array length suggest that definition into 2 n times the size of the power, the n anticipation of the array length according to you decide,

Line 28 output

 printf (" % s % d % d % d % s \ n ", 
Cla [I]. Num, cla [I]. Name, cla [I] the teacher, cla [I] term, cla [I] person);

, the teacher's name is a string output, so the structure should be changed to:

 struct Class {
Int num. 
Char name [10]. 
Char the teacher [10].//the teacher name is the string 
Int term; 
Int the person; 
};
