simple pointer to structures

Question

I am trying to write simple program to collect data for certain number of students and output it in the end. After I enter data for one student, my program crashes.

Here is the code:

#include <stdio.h>
#include <stdlib.h>
typedef struct Student Student;
struct Student{
    char name[20];
    char lastname[20];
    int age;
};

main() {
    int i;
    int n;
    scanf("%d",&n);


    Student *pStudents = NULL;
    pStudents = (Student*)malloc(n*sizeof(Student));

    for(i=0;i<n;i++) {
        printf("Enter the students name: \n");
        scanf("%s",(pStudents+i)->name);
        printf("Enter lastname: \n");
        scanf("%s",(pStudents+i)->lastname);
        printf("Enter age: \n");
        scanf("%d",(pStudents+i)->age);
    }

    for(i=0;i<n;i++) {
        printf("%s",(pStudents+i)->name);
        printf("%s",(pStudents+i)->lastname);
        printf("%d",(pStudents+i)->age);
    }

} 

Thanks in advance.

Answer 1

   scanf("%d",(pStudents+i)->age);

the argument of scanf must be of a pointer type.

Change (pStudents+i)->age to &(pStudents+i)->age.
