Question

Help on understanding C structs

Answer 1

#include<stdio.h>

typedef struct telephone
{
char *name;
int number;
}TELEPHONE;

int main()
{
TELEPHONE index;

index.name = "Jane Doe";
index.number = 12345;
printf("Name: %s\n", index.name);
printf("Telephone number: %d\n", index.number);

return 0;
}


Say I have something like this, how would adding more names and their associated phone numbers work? Every new name I add would replace the old one right?

Answer 2

ur not taking any input for the name? how do u expect to add names then?

Answer 3

Say I had a way to input names, how would I make the struct accept multiple names and their associated phone number? Because the way I see it, it only accepts one single name and number right now.

Answer 4

struct declare structures. Except for access control, they're the same as classes in object oriented languages. Each instance of a struct (index is one TELEPHONE) holds the attributes of one (in this case) telephone. If you want to have many telephones, you'll probably want an array of structs (struct pointers).
