9). Exercises: Input and Output 1. 4, do the following experiments: First, compile and run it to see its normal behavior. What happens if you enter a non-numeric value for the birth year? What happens if you enter a name such as Curious George as your name? What happens if you remove the following line? using namespace std; Replace the statement cin >> yourName; with the statement getline(cin, yourName); and try Curious George again. Can you explain the differences in behavior between cin >> and getline()?

Each of these values can be stored in a variable of type double. Then compute and display the change that will be given to the user. Express the change in terms of the number of $10 bills, $5 bills, $1 bills, quarters, dimes, nickels, and pennies. 82 and the customer pays with a $100 bill, then the change should be: two $10 bills, one $5 bill, one $1 bill, no quarters, one dime, one nickel, and three pennies. Convert the amount that is owed the customer to pennies, which can be stored as an int and then use the integer division operators.
