How do you create student record using c language?

Answer 1

A "student record" is an example for a structured data type, which combines several elements into one type. In C, this is accomplished using the struct keyword. For example, a variable of a student record containing a student's id and a pointer to the student's name could be defined like so:

struct {

unsigned long id;

const char* name;

} student;

However, this approach does not support re-use of the student record data type. Complex data types are typically implemented with the typedef keyword, which allows reusing the type:

typedef struct {

unsigned long id;

const char* name;

} StudentRecord;

StudentRecord student;

While the second example is functionally identical to the first, you can now use the StudentRecord type elsewhere. For example, you could declare a function to print a student's details, based on a pointer to the student's record:

void print(const StudentRecord* const me) {

printf("ID: %-8ld %s\n", me->id, me->name);

} // print
