Ihave constructed a binary search tree and then insert it following four items. then I want to print tree in preorder form. in my output file there is extra things as below.
for example
i want this
int float mytype itisatype
but output is
int float mytype itisatype 0xbffff8ac
why do I have these extra characters?

if there is someone who has any idea about this problem ,please help me.
