C++ Programming Ex 5-7

Letn = akak-1ak-2...a1a0be an integer andt = a0- a1+ a2- ... + (-1)kak.

It is known thatnis divisible by11if and only iftis divisible by11.

For example, suppose thatn=8784204. Thent= 4 - 0 + 2 - 4 + 8 - 7 + 8 =11.

• Because11is divisible by11, it follows that8784204is divisible by11.

Ifn=54063297, thent= 7 - 9 + 2 - 3 + 6 - 0 + 4 - 5 =2.

• Because2is not divisible by11,54063297is not divisible by11.

Solve a program that prompts the user to enter a positive integer and then uses this criterion to determine whether the number is divisible by11.

Example output (Program output should be in a similar format):

121 is divisible by 11 12 is not divisible by 11
