It probably won't be simple.
One approach is to read the entire file into a vector. Make whatever changes you like to the vector. Then save the contents of the vector back to the file.

If you need such thorough examples, then you really should be consulting your textbook, or look for an online tutorial. There is a tutorial on this site which covers the basics of C++ but doesn't get into the more advanced topics which you are asking about.
