Thread: define vs. char[]

Hi..

Through my program i use some connections to sockets and it did seem to work earlier but not anymore after I changed define to char[].

FROM:

Code:

define PORTlastNumber 6;
define PORT  24006;
define HOST "smr";
define DIRSIZE 19000;//8192
define SmrDemoAddress;

TO:

Code:

int PORTlastNumber = 6;
int PORT = 24006;
char HOST[] = "smr";
int DIRSIZE = 19000;//8192
int SmrDemoAddress;

I did it because I needed to use the portnumber elsewhere and made it global, but now it does not want proceed when reached Hostname, it simply stalls.. And I cannot write the value of HOST om the screen without it just stalls..
Please help me..

Since your code worked with #defines at the end, it means there are an awful lot of them missing in your code.

Say you had
int myport = PORT
With the define PORT 24006;
this expands to
int myport = 24006;

But if you have just int PORT = 24006; then the attempt to use it is a syntax error.

Sorry, it was not the exact code.. Just one like it as I remembered it..

Thanks, but I have found the problem.. There was no problem in this change.. The problem was that I had not defined the extern command right in the file where I should use it..

the problem was:

Code:

extern HOST;  
Should have been: 
extern char HOST[]

Such a litte thing screwed it all up.. Well thanks for your time..

Sorry.. Thorght that the problem was due to the change from define to char[].. It seemed that way in my eyes...
I did not potentially ask a question that was not related to the problem.. Sorry again..
