This all works. Thanks.

Is there way to switch two words too?

Hey Daniel what's that operator ^= ? I never see it O.o

[Lee]

Assignment XOR (exclusive disjunction).

That's simple stuff - I understood nearly 1% of it easily!

XOR = Toggle each bit if the correspondent bit of both the operands are different.

Example (number represented as bits)

111 XOR 111 = 000 (all bits equal)
000 XOR 111 = 111 (all bits different)
001 XOR 000 = 001 (only last bit different)

[OT]@danielkza: So if the 2 bits are different, the result will be the bit that is less close to 000?

i.e:
010 XOR 011 = 011? // 011 > 010? Or it doesn't work like that with bits?
100 XOR 011 = 100? // 100 > 011?[/OT]


@AoD90:

Try this:

PHP Code:

// lenz = number of characters to swap.
stock swap_words( wordA[], wordB[], lenz )
{
    new temp[ 250 ]; // 250 will be the maximum number of character the wordA can contain. Edit this to your liking.
//    You must make sure that lenz is NOT bigger than temp's size.
    
    format( temp, lenz - 1, "%s", wordA );
    format( wordA, lenz - 1, "%s", wordB );
    format( wordB, lenz - 1, "%s", temp );
    
    return 1;
} 


Example of usage:

PHP Code:

#include <amxmodx>

// lenz = number of characters to swap.
stock swap_words( wordA[], wordB[], lenz )
{
    new temp[ 250 ]; // 250 will be the maximum number of character the wordA can contain. Edit this to your liking.
//    You must make sure that lenz is NOT bigger than temp's size.
    
    format( temp, lenz - 1, "%s", wordA );
    format( wordA, lenz - 1, "%s", wordB );
    format( wordB, lenz - 1, "%s", temp );
    
    return 1;
}

public plugin_init()
{
    register_clcmd( "say /swap", "myFunction" );
}

public myFunction( id )
{
    new HelloWorld[] = "HelloWorld!";
    new WorldHello[] = "WorldHello!";
    
    swap_words( HelloWorld, WorldHello, 11 );
    client_print( id, print_chat, "HelloWorld: %s    WorldHello:    %s", HelloWorld, WorldHello );
}

I got some error:

Error:Must be a constant expression; assumed zero on line 98
Error:Invalid array size (negative or zero) on line 100
Error:Undefined symbol "temp" on line 100

Fixed last post.
Test and tell me the results.

Very nice. Thanks a lot
