text comparing

Maybe I didn't understand something but I thought you said that quzahs didn't recognise between numbers and letters. If I understand his code, it is based on the spaces. But I can't use spaces to recognise because when I get the plate it could have mistakes in the spaces and sais that there is a space where there isn't.

For example, it sais that the plate in the picture is 111 1 AAA, so we have one space more than in the pattern that is 1111 AAA, so I can't use the spaces for recognison.

What a do is : I get 111 1 AAA, I make it become 1111AAA and compare it with the pattern that is in this case 1111AAA (whithout spaces).

Maybe I'm explainig something that you already undesrtand, but I re-appologise for my very very bad english, so maybe I'm confused.

Same code, minor change to skip spaces. Same end result:

Code:

#include<stdio.h>
#include<ctype.h>
int parse( char *s )
{
    if( s )
    {
        int a = 0, b = 0, c = 0, num = 0;
        while( *s && (isalpha( *s ) || ' ' == *s) ) a += (' '!=*s++);
        while( *s && (isdigit( *s ) || ' ' == *s) ) b += (' '!=*s++);
        while( *s && (isalpha( *s ) || ' ' == *s) ) c += (' '!=*s++);
        
        num = (a * 100) + (b * 10) + c;        

        switch( num )
        {
            case  43: /*    1111  AAA */ case 141: /*  A 1111  A */
            case 142: /*  A 1111  AA  */ case 241: /* AA 1111  A */
            case 242: /* AA 1111  AA  */ case 150: /*  A 11111   */
            case 250: /* AA 11111     */ return 1;       
            default: return 0;
        }
    }
    return 0;
}

int main( void )
{
    char *tests[] =
    {
        "911aB", "AAA 564", "6114 DFa", "1111Aaa", "aa 11", "GF 1511 SS",
        "aa111aa", "aa111a", "aa111aaa", "XX 11111", "a@ 11311", "a 4511",
        "a1111"
    };
    size_t x;
    
    for( x = 0; x < sizeof tests / sizeof tests[0]; x++ )
    {
        printf("parse( %s ) == %d\n", tests[x], parse( tests[x] ) );
    }
    
    return 0;
}

Quzah.

Ok now I understand. Thank you very much, I like it a lot.

I hope my boss will like it to. ;-)

Thanks a lot.

Have them send me a check.
