characters and files in C++
<p>I have to make a program where the filename is composed of two parts: the first one is fixed and the second one can change during the program e.g "fixpart_integer.dat". I tried to do this in C++ but I did not succeed. The fisrt probelm is: how can i convert a number to a char ; and how can i concanate these 2 characters ; and how to declare this final char in the right way in order to open this filename ?</p>

<p>Many questions but I did find an easy way to do this.</p>
