Objective

Create a helper namespace header file that will provide an easy$-$to$-$use interface for frequently used functionality.

Namespace

Create a new Helper.h header file. Within it$,$ declare a namespace named 'Helper'. Inside the namespace, declare AND define $($within the namespace body $\{\})$ your first helper method:

int GetValidatedInt$($const char$*$ strMessage, int nMinimumRange $=0,$ int nMaximumRange $=0)$;

This function should first display the provided message to the screen then use cin to get an int from the user. Error check and validate to ensure a legal integer was entered. If not, clear the cin buffer using clear$()$ and ignore$()$ and try again $($Note: the buffer still needs to be cleared even if this step was successful$).$

If a legal integer was entered, check its value to see if it is within the provided minimum and maximum range $($inclusive$).$ If the user input was within the range, return the integer. If not, get input again. The range check should be ignored if BOTH the minimum and maximum parameters are $0,$ so any valid integer is acceptable.

You should be using a loop so that the method does not return until a valid and within range $($if the range is not $0)$ integer was totally provided.

Customize

Create at least two more helper functions that will handle generic code that you find yourself consistently re$-$writing in SPR$.$ Some helper ideas include:

Return random number within a range

Print a menu $($array of strings$)$ and return the users selection

Clear and ignore the cin input buffer

Print a provided integer in binary, hex, or oct

Copy string reference
