How to concatenate strings - ForestCZE - 24.02.2018

Hello everyone

I've got following code:

PHP Code:



new radiolist[500]; //I've got about 16 radios, but it's not necessary to show all lines of my code

strcat(radiolist, "Stanice\tPosluchačů\n");

strcat(radiolist, "Vypnout rбdio\n");

strcat(radiolist, "Evropa 2\t%i\n", listeners[0]);

strcat(radiolist, "Rбdio Express\t%i\n", listeners[1]);

strcat(radiolist, "Dance Rбdio\t%i", listeners[2]);

ShowPlayerDialogEx(playerid, D_RADIO, DIALOG_STYLE_TABLIST_HEADERS, "Rбdio", radiolist, "Zvolit", "Zavřнt");

The question is - How correctly use format and strcat because of "listeners" variable, please? Thanks in advance for a help

That's usually how it's done:

PHP Code:



new message[24], value = 5;


strcat(string, "hello");

format(string, sizeof string, "%s world! %i", string, value);

You pass the actual string to the format function and add whatever you need.

It's usually better to use strcat in case if you don't need to pass variables into the final dialog/message but if you do then you can reformat the string like what iKarim said.

You pass the actual string to the format function and add whatever you need.

I'm sorry, but I probably didn't understand you. This code:

PHP Code:



new radiolist[500];

strcat(radiolist, "Stanice\tPosluchačů\n");

strcat(radiolist, "Vypnout rбdio\n");

format(radiolist, sizeof(radiolist), "Evropa 2\t%i\n", listeners[0]);

does not work.

You need to pass the radiolist variable as a param in the format too, also notice the %s place.

PHP Code:



new radiolist[500];

strcat(radiolist, "Stanice\tPosluchačů\n");

strcat(radiolist, "Vypnout rбdio\n");

format(radiolist, sizeof(radiolist), "%sEvropa 2\t%i\n", radiolist, listeners[0]);

Yes, I already realized that and you were faster than my edit. Thank you so much

You could use sprintf from here so that you can format strings within strcat.
