    Question Find String inside Array?

    Hello, I want to search for a string inside one array, and get the position (index) of the first (or last) char when this was found... I tryed this searching for "play":

    Code:
    		   while (i<(TamNew-5)){ //find if this is a spawn class
    				if((NewStr[i]=="p")&&(NewStr[i+1]=="l")&&(NewStr[i+2]=="a")&&(NewStr[i+3]=="y"))
    				{
    					p=i;
    					break;
    				}
    				i++;
    		   }
    but didn't work! I tryed before this:


    Code:
    char *p;
    p = strstr(NewStr, "play");
    but P return the mem address, not the array index that I need!

    any clues?

    thanks!!!

    p-NewStr gives you an index
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    Code:
    char *loc;
    loc=p-NewStr;
    printf("&#37;d",loc);
    will give you the index of the first char in the string

    seems like me and vart posted the same replay in the same time

    didn't work, make the game abort... any other way? maybe without use pointers?

    thanks!

    NewStr is a array... could be that?

    char NewStr[150];

    i guess it should be
    Code:
    char *loc;
    loc=New_str-p;
    printf("&#37;d",loc);
    it works with me

    seams that I can't create pointers... is just create one more than the game abort.

    is there a way to do that search? why not working the i+1 index that I did? I remember to do this a lot in the past...

    worked now!

    Code:
    char	*ptr = malloc(151);
    
    			   strcpy(ptr,NewStr);
    			   origem = strstr(ptr, "origin"); //find the origin position
    			   loc = origem-ptr;
    			   free(ptr);
                   ori = loc + 8;
    ori = 12! perfect! thanks!
