Thread: pointers to structures

Code:

typedef struct {
	int nr;
	char name[21];
	char afd;
}
EMPLOYEE;


void print (EMPLOYEE);
void get(EMPLOYEE*);

int main (void)
{    
        EMPLOYEE a1= {1111,"Bob The Builder",'B'},a2={0};

	
        get(&a2);


        print(a1);
        print(a2);
}
void print(EMPLOYEE a){                                                      // copy and paste									
	printf("%d %s %c",a.nr,a.name,a.afd);
}
void get(EMPLOYEE *a){                                               //pointer naar structure
	printf("arbeider(stamnr,name,afd)");
	scanf("%d %s %c",a.nr,a.name,a.afd);
}

in the first function print, i just copy the structure, in second on i try to pass the structures adres,
then what are the arguments of scanf;

Code:

scanf("%d %s %c",&a->nr,&a->name,&a->afd);

You could also try

Code:

scanf("%d %s %c",&(*a).nr,&(*a).name,&(*a).afd);

if you wish.

Edit: Corrected. Sorry, missed something.

Yes, that's correct. Little error on my part. /*mod edit: non pg-13 language removed(kenfitlike)*/

this is very helpfull so far, thanx.
who can add/correct statements that can be usefull with structures

EMPLOYEE e1; //record
EMPLOYEE *p; //pointer to record


p=&e1; //adding adres to pointer

e1.name //value of name within record

&e1.name //adres of name

p->name //value of name within record

p.name //adres of name

Did the teacher that assigned you this homework used to teach first grade? I'm suprised they didn't have to walk around the house and look for different shapes. Anyway read the homework policy because that's clearly homework.

i was looking for some generalisation because the faq dont seem to cover this. and sorry if my newb questions aren't interesting to you. Perhaps a link to tutorials on this matter?

The cprogramming tutorial on structures should pretty much cover all of this.

its pointer arithmetics that im looking for, notting there realy
http://faq.cprogramming.com/cgi-bin/...&id=1073086407

thanx for helping me out anyway

Code:

#include<stdio.h>

int main (void){

	typedef struct {
	  int nr;
	  char naam[20];
	}RECORD;

	RECORD r1={1,"jones"},*p;

	p=&r1;

	printf("%d %d",&r1.naam,&(r1.naam));

return 0;
}

i'm just tring to sort out all possible indirectives by tring to print them out, &r1.naam prints out other adres than &(r1.naam)
