Count characters in string - MP2 - 23.07.2011

How do I make a function that can return the number of a certain character in a string? For example I want 'CountChars("~", string) to tell me how many ~'s are in string.

Thanks.

pawn Код:

CountChars('~', string);

stock CountChars(ch, str[], len = sizeof(str))
{
     new count;
     for(new i; i != len; i++) if(str[i] == ch) count++;
     return count;
}

Untested.

Would it be better with strfind though?

pawn Код:

stock CountChars(txt[],ch='~')
{
    new d,cnt;
    while(txt[d] != EOS)
    {
        if(txt[d] == ch) cnt++;
        d++;
    }
    return cnt;
}

Strfind finds a _string_ and returns it's _position_. The function I gave you counts all the _characters_ and returns the _amount_. 2 differences.
