How is "tmpnam()" used in C++?
Explanation
tmpnam() is an I/O function which is used to create a unique filename and store it in a array. The size of the array can also be specified in this function. If this function is executed successfully a pointer to the filename is returned, otherwise a null pointer is returned.

In the above example the "tmpnam()" is used to create temporary filename that is not similar to any
other file.
