[SOLVED] [C] Regarding structures and scanf

[thomashw]

Can someone explain how to use scanf with a structure?

 

Here's the code I'm trying to use, and it's not working:

 

#include<stdio.h>

typedef struct hey{
double x;
double y;
} hey;

int main()
{

hey whatsup;

scanf( "%f", &whatsup.x );
printf( "%lf", whatsup.x );

}

 

Whatever I enter, the printf function prints "0.000000".

It looks to me like one can't create a reference to a variable in a structure.  (Maybe someone who knows C can tell us how?)

 

 

Why not just do

 

double tmp;

scanf("%f", tmp);

whatsup.x = tmp;

 

 

Edit:  Oh this is solved....  Hrmm never mind.  Just of curiosity, how did ya do it?

[thomashw]

scanf( "%f", &whatsup.x );

 

should have been:

 

scanf( "%lf", &whatsup.x );

 

Doh.

Ahhhhh....
