Help with C syntax

I can't figure out how to use #declare the same way you use CONST. I found this page:

But I'm not sure if it's even C!

Please help.

Use #define.

Code:

#define YOURCONST 1234
printf("%d", YOURCONST);

Plasma's solution will work but as an alternative you can use the const keyword:

Code:

const int x = 5;

printf("Constant x = %d\n", x);

The #define method given by Plasma has the preprocessor replace all occurances of YOURCONST with the string of text (its not actually a value as such) 1234 before compiling. This is fine for most solutions, except when you want some finer control, for example:

Code:

#define YOURCONST 1234
const int x = 5;

/* Okay, because x is a variable */
printf("Address of x = %d\n", &x);

/* Not okay, because YOURCONST is just a number */
printf("Address of YOURCONST = %d\n", &YOURCONST);
