You need to use == instead, as follows: if(*_item == 'T') Also, you could use the following code which I tend to prefer: if(_item[0] == 'T') since a string is an array of characters in C, and if you're not used to pointer notation as shown by Garrett, this is a bit easier to follow. Realize that all arrays start with 0 in C, not 1 like in Fox.
