CScript While Loops

The while loop repeats a statement until the conditional test at the top proves false. The general form of a while statement is:

while ( expression ) statement

Because the expression is tested before the statement is executed, the statement part can be executed zero times. The following example returns the length of a string.


string_length(string)
{       
    int i = 0;
    if (string != NULL)
    {
        while (string[i] != '\0')
            i++;
    }

    return(i);
}

The while loop is used to look at the characters in the string one at a time until the NULL character is found. Then the loop is exited and the length is returned.
