made it quickly, it should work well.

pawn Code:

stock check(string[],lol[])
{
   for(new i = 0; i != strlen(string);++i)
   {
       if(!strcmp(lol,"uppercase"))
       {
           if(string[i] >= 'A' && string[i] <= 'Z') return printf("It has uppercase letters.");
       }
       else if(!strcmp(lol,"lowercase"))
       {
           if(string[i] >= 'a' && string[i] <= 'z') return printf("It has lowercase letters.");
       }
       else if(!strcmp(lol,"numbers"))
       {
           if(string[i] >= '0' && string[i] <= '9') return printf("It has numbers");
       }
   }
   return 0;
}

//usage...
new blahblah[] = "abcdefkddkds2";
check(blahblah,"numbers");
new blahblah[] = "123232313FFSFFDSa";
check(blahblah,"lowercase");
new blahblah[] = "asdidsjaij123j21ij321A";
check(blahblah,"uppercase");

This way is pretty simple... instead of what he did..
