4. Everything seems to be compiling successfully, but program crashes the gets to

conversion >> myCharInsert;

The problem is that you are trying to dereference(access) myCharInsert(declared as a char* ) which is pointing to a random location in memory(which might not be inside the user's address space) and doing so is Undefined Behavior (crash on most implementations).

EDIT

To insert a char into a string use string& insert ( size_t pos1, size_t n, char c ); overload.
