Can you think of a situation where your program would crash without reaching the breakpoint which you set at the beginning of main()?
C++ allows for dynamic initialization of global variables before main() is invoked. It is
possible that initialization of global will invoke some function. If this function crashes
the crash will occur before main() is entered.
Name two cases where you MUST use initialization list as opposed to assignment in
constructors.
Both non-static const data members and reference data members cannot be assigned values;
instead, you should use initialization list to initialize them.
