Sounds like you're in a hurry... First of all, DON'T USE <iostream.h> and <string.h>... Instead use <iostream> and <cstring>. Second, main can't be declared like that, it has to be: int main(){ //code here return 0; } Cheers! EDIT: and yes, you are using system(), that means you have to …

And what is the problem? To help you a little, your sequence is the same as: (-1)^2 * x^1/1! + (-1)^3 * x^2/2!...

Try with something easy for start.

If print is a function... you need brackets: (currnode->contact).print();

You can use ostringstream from <sstream>, i use that, although it may not be the easyest way. [CODE] #include <sstream> std::string Convert (float number){ std::ostringstream buff; buff<<number; return buff.str(); } [/CODE] ostringstream and istringstream are basically the same as cout and cin, but they don't print stuff on screen.
