Array to string - Sickae - 01.04.2015

Hey,
I want to store an array's full content in another variable. I know I can make it by going through every slot but I'm pretty sure there's a much easier way I'm missing out. Please help me!

Re: Array to string - CalvinC - 01.04.2015

Here's an example:

pawn Код:

new array[2][5]; // Declare the array
array[0] = "Test"; // Make array 0 contain "test"
array[1] = array[0]; // Make array 1 contain what array 0 contains

You cannot store several characters in a single variable if that's what you mean.

That's what I meant when I said I could go through it slot by slot but I dont want to.
Here's what I want:

Quote:

new Input[5] = {a,b,c,d,e};
new Str = Input

But that gives error ofcourse. So basically I want Str to store "abcde".

Use functions you can't assign arrays like that in PAWN.

memcpy or strcat

If you want to insert characters into a string, use strins.

If you want to copy an array (array2 = array1), use memcpy.

Код:

new Input[5] = {a,b,c,d,e};
new Str[sizeof(Input)] = Input;

But I don't understand what do you want. You can use index easily for that:

Input[0] = "a"
Input[1] = "b"
Input = "abcde"

Why to copy that you already have?

Why do you even need that?

new Input = {'a','b','c','d','\0'};
print(Input);

EDIT:Oops sorry, even you were criticizing that :P

You can't store several pieces of data in a variable, that's why we use arrays for containing words.
Each variable can store 1 piece of data.

pawn Код:

Var1 = "H";
Var2 = "i";

You cannot do

pawn Код:

Var = "Hi";

It's the same with arrays, but they're like several variables.
You could say using Array[3] contains 3 "variables".

pawn Код:

Array[0] = "H";
Array[1] = "i";
Array[2] = "\0";

Which is the same as just doing

pawn Код:

Array = "Hi";

If the array is declared using

pawn Код:

new Array[3];

Because each "number" is like 1 variable, so here we have 3 variables, which and can store 1 piece of information each.
The reason we need 3 is because of the null constant, AKA "\0", it tells the compiler that the string ends where the null symbol is.

Doing this

pawn Код:

new Input = {'a','b','c','d','e'};
print(Input);

Isn't possible, because this , is supposed to hold an integer generally but doing this is possible:

pawn Код:

new Input[6] = {'a','b','c','d','e'};
print(Input);//would print 'abcde'
//tests:
for(new i = 0; i <6; i++) printf("%d:%s",i,Input);
/*
Would Print:
0:a
1:b
2:c
3:d
4:e
5: ' '//Means an empty message because the fifth cell is for the \0 , the null character
*/

It was just an example. The data of Input isn't fixed, it's what the user writes in it. To be more specific it's an input styled dialog and I want to use the given input outside of the callback 'OnDialogResponse' so I need a global variable for it. But you already helped me a lot, thanks guys.
