Write a complete C$++$ program that does the following:

Prompts the user for two lower case letters. The first letter must precede the second in alphabetical order. Also, the characters

cannot be the same. For example, $\text{'}$e$\text{'}$ followed' by $\text{'}$h$\text{'}$ are valid inputs, but $\text{'}$h$\text{'}$ followed by $\text{'}$e$\text{'}$ is invalid.

If the user enters invalid inputs, force the user to enter valid inputs.

Hint: cast each char as an int and store the result for each in an int variable. Compare the two ints to determine if one precedes

the other.

Pass these two characters as input to a f

unction called printStripedSquare that prints a $5$ x $5$ square with the following properties:

Odd numbered rows consist of the first char.

Even numbered rows consist of the second char.

Example main f

unction that uses printStripedSquare:

int main$()\{$

char a$,$ b;

int x$,$ y;

cout $<<$ "Enter two characters, first must precede second in alphabetical order: $"$;

cin $>>$ a $>>$ b;

x $=($int$)$ a;

y $=($int$)$ b;

while$($FILL IN$)\{$

FILL IN

$\}$

printStripedSquare$($a$,$ b$)$;

return $0$;

$\}$
