Write pointer to file in C

Question

typedef struct student {
  char *name;
  char *surname;
  int age;
} Student;

I need to write the structure into a bina

Answer 1

if you want to directly write the structure as it is to a file you would want to define the sizes of name and surname rather than dynamically allocating it.

typedef structure student { char name[100]; char surname[100]; int age; } 

else you will need to write each info in the structure one by one.
