c语言按结构中的值排序

Question

I can't understand what wrong here. I run debug and can't find the problem it's supposed to work. the problem is that if I insert few students and then chose (3 option) to sort it by nakaz, it prints 0 instead of the actual value number. but I can see that it all good in the F7 thank you very much in c language

ilustration

    #include <stdio.h>
    #include <string.h> 
    #include <stdlib.h>


    typedef struct student* ps; //struct student pointer
    typedef struct student student;

Answer 1

You've got the wrong output type on the points printf. You have it set to "%lf" when it should be "%d" based on the expected integer type of the variable:

void printAllStudents(ps head){
    while (head != NULL){
        printf("The student %s points is %d \n", head->name, head->nakaz);
        head = head->next;//printing all dogs
}
