Loop Through Characters in String

Could anyone provide an example on how to loop through each character in a string? What I need to do is check if the letter is upper case and then change it to lower case or if it is a space, remove it. I know how to do the change the characters, but I am not sure how to actually get to each character.

Re: Loop Through Characters in String

PHP Code:


		
			
    new len = strlen(mystring);
    for (new i = 0; i <= len; i++)
    {
        if (mystring[i] /* your conditions */)
        {
             // your adjustments
        }
    }

A more efficient way:

PHP Code:


		
			
new n=0;
while (mystring[n] != '\0') {
    
     // Do your stuff here...

    n++;
}

Re: Loop Through Characters in String

A complete function:

PHP Code:


		
			
stock StrToLowerRemoveBlanks(const String:str[], String:buffer[], bufsize) {

    new n=0, x=0;
    while (str[n] != '\0' && x < (bufsize-1)) { // Make sure we are inside bounds

        new char = str[n++]; // Caching
    
        if (char == ' ') { // Am I nothing ?
            // Let's do nothing !
            continue;
        }
        else if (IsCharUpper(char)) { // Am I big ?
            char = CharToLower(char); // Big becomes low
        }

        buffer[x++] = char; // Write into our new string
    }

    buffer[x++] = '\0'; // Finalize with the end ( = always 0 for strings)

    return x; // return number of bytes written for later proove
}

but not tested ;)

Re: Loop Through Characters in String

Would it be something like this?

PHP Code:


		
			
new n = 0;
while (gamemode[n] != '\0') 
{
     if (IsCharUpper(n))
     {
         n = CharToLower(n);
     }
     if (IsCharSpace(n))
     {
         //do what?
     }

     n++;
}
