i have these variables:

char server[] = "myserver.hol.es";
int num = 12345;

how can i join them into "myserver.hol.es/12345"?

Or 'sprintf_P()', to store the format string in program memory:-

void setup()
{
    Serial.begin(115200);
    char server[] = "myserver.hol.es";
    int num = 12345;
    char buffer[25];
    sprintf_P(buffer, PSTR("%s/%i"), server, num);
    Serial.println(buffer);    // Prints: "myserver.hol.es/12345"
}

i try these code but the output was 518/12345

char server[]="myserver.com";
int num = 12345;
char buffer[50];
void setup(){
  Serial.begin(9600);
  sprintf(buffer,"%d/%d",server,num);
  Serial.print(buffer);
}
void loop(){
}

Oh good.
What you did wrong in your last post was that this "%d/%d" should have been "%s/%i".

'%s' is string
'%i' is integer

All's well that ends well. :slight_smile:
