Answer 1

Change

while(beverage!='e'||beverage!='E'); // Condition becomes true always 

to

while(beverage!='e'&& beverage!='E');  

And similarly replace all || by && in first while loop conditional expression

while(beverage!='A' && beverage!='B' &&beverage!='C'&& beverage!='D' && beverage!='E' && beverage!='a' && beverage!='b' && beverage!='c' &&
     beverage!='d' && beverage!='e')
