Exercise 5: Write a complete C++ program that ask the user to input two integers, then print if they are divisible by each other or not ( the division has no carry). If they

are divisible print their division results on each other. Make sure avoid the divide by

zero situation before testing their divisibility.

Here is a sample output:

Exercise 6: Write a complete C++ program that calculates the cost of train ticket as the following,

If the passenger is an adult (i.e. +17 years old) his ticket costs 150 SR,

If the passenger is a kid (i.e. 16~3 years old) his ticket costs 80 SR,

If the passenger is a baby (i.e. less than 2 years old) his ticket costs 40 SR,

Also, if the passenger wants a meal on the train it cost for the adult is 25 SR, 15 SR

for the kids meal and the baby meal is for free.

If the passenger has a discount coupon he gets 15% off the total cost.
