C++ Program to Create a Temporary File
Here, we will see how to create a temporary file using a C++ program. Temporary file in C++ can be created using the tmpfile() method defined in the <cstdio> header file. The temporary file created has a unique auto-generated filename. The file created is opened in binary mode and has access mode “wb+”. These temporary files are automatically deleted when the program is terminated or when they are closed in the program using fclose().
