char *a="hello"; char *b="hello"; assert(a==b); // true, the compiler knows the two hello are the same and assign the same address(sort of id() in python) to a and b But the following is not char *a="hello"; char *b="_hello"; char *c=b+1; assert(a==c); //false, even the content they point to are the same However, string in the above are not basic types of C and if you want to compare the value(like comparing integer), you need to use function like strcmp() which again compare byte by byte in the above example and give true. -- http://mail.python.org/mailman/listinfo/python-list
