Properly get string - mads232 - 01.03.2015

Of what I've read, you make a string by making an array.

Let's say

Код:

new newString[128];

Then you store strings in this. Let's say

Код:

newString = "Hello everybody";

But how do you GET this string then?
newString[0] will get the first letter, but how do you get the whole "Hello everybody"

Am I doing strings wrong, or am I just a noob? :P

-Thanks in forwards

Just "newString". No index necessary.

Thanks for replying. The problem is, that gives me the error 033: array must be indexed.

Hello,

Here's a simple example to show you how it works.

Код:

// We create a string and put "Hello" inside.
// Note: We need 6 cells because there is an end-of-string caracter at the end ("\0").
new sText[6] = "Hello";

// Now we can show the string using functions:
printf("%s buddy", sText);

// It will render as: "Hello buddy"

Hope I helped. If you still have problems after that, please show us the portion of code you're trying to run.

Hello

Thanks, I already read that one. So as it didn't really help me, here's an example:

I'm creating this:
OnPlayerChangeAnim(playerid, newAnim, oldAnim)

Whenever I want to compare newAnim to an anim, I do this:

Код:

new baseballBat[32];
baseballBat = "BASEBALL_BAT_1";

if(strcmp(baseballBat == newAnim)
{}

Then it tells me that baseballBat in the strcmp should be indexed. When I do baseballBat[0], I get no errors, because it of course is indexed then.
So how do I strcmp the whole String like this? Should I format baseballBat?

Hold on a second. That is not the correct strcmp syntax. Do it like this:

pawn Код:

if(!strcmp(baseballBat, newAnim, true)) //true means that we don't care about the capital letters (for example, test is identical to TeSt)
{
//they are identical
}
else
{
//they are not identical, at least one character is different
}

!strcmp would be != and I want ==, therefore strcmp, right?..

Also true is optional, and I choose that it should care for capital letters

Re: Properly get string - CalvinC - 01.03.2015

You don't use == or != in strcmp, the code he provided will check if baseballBat and newAnim matches correctly, but yeah you can change the "true" to "false" if it should care for capital letters.

I mean the ! in front of strcmp would check if they DIDN'T match?

Re: Properly get string - HazardouS - 01.03.2015

In an if-statement, !variable means "variable == 0". Strcmp returns 0 when the strings match, so !strcmp means match. When you say if(variable), it actually means if(variable != 0), so "if( strcmp(string1, string2) )" is true when string1 and string2 do NOT match.
