Write a
86 cents can be given as
3 quarter (s) 1 dime (s) and 1 penny (pennies)
Use coin denominations of 25 cents (quarters), 10 cents (dimes), and 1 cent (pennies). Do not use nickel and half-dollar coins. Your program will use the following function (among others):
void computeCoin(int coinValue, int& number, int& amountLeft) ;
//Precondition: 0 < coinValue < 100 ; 0 <= amountLeft < 100.
//Postcondition: number has been set equal to the maximum number
//of coins of denomination coinValue cents that can be obtained
//from amountLeft cents. amountLeft has been decreased by the
//value of the coins, that is, decreased by number*coinValue.
For example, suppose the value of the variable amountLeft is 86. Then, after the following call, the value of number will be 3 and the value of amountLeft will be
11 (because if you take three quarters from 86 cents, that leaves 1 1 cents):
computeCoins (25, number, amountLeft) ;
Include a loop that lets the user repeat this computation for new input values until the user says he or she wants to end the program. (Hint: Use integer division and the operator to implement this function.)

- Write a program that takes a bank account balance and an interest rate as an input. And then outputs the value of the account in 5 years. The output should show the value of the account for two different methods of compounding interest: annually and monthly. When compounded annually, the interest is added once per year at the end of the year. When compounded monthly the interest is added in 12 times per year. On annual interest, you can assume that the interest is posted exactly one year from the date of deposit. In other words, you do not have to worry about interest being posted on a specific day of the year, like December 31. Similarly, you can assume monthly interest is posted exactly one month after. Since the account earns interest on the interest, the account should have a higher balance when interest is posted more frequently. Be sure to adjust the interest rate for the time period of the interest. If the rate is 5%, then when posting monthly interest, you use (5/12%).

If the temperature is between 20 to 40 degrees Fahrenheit, suggest the user go skiing; if the temperature is between 41 to 60 degrees Fahrenheit, suggest the user go hiking; if the temperature is in the range of 61 to 80, suggest swimming. For all the temperatures out of these ranges (too cold or too hot), then suggest staying inside.arrow_forward
- Write a program with total change amount (in cents) as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies. Hint: Start from the largest denomination. Divide the change amount by the number of cents in the denomination to get the number of coins used. The remainder of the division is used to find the number of coins used in the next denomination. Ex: value // 100 gives the number of dollars used. The remainder is divided by 25 to find the number of quarters used. Ex: If the input is: 0 (or less than 0), the output is: No change Ex: If the input is: 45 the output is: 1 Quarter 2 Dimesarrow_forwardWrite a program that outputs all the integers between 100 and 1000 (inclusive), that are divisible by 5 and also 6. (This means start at 100 and go up to 1000, but only output integers that are divisible by both 5 and 6.) Remember what "divisible" means - if a number is divisible by 5, there is no remainder when you divide it by 5. If a number is divisible by 6, there is no remainder when you divide it by 6.

Letter grades are A, B, C, D, and E, possibly followed by + or -. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F-. A + increases the numeric value by O.3, a – decreases it by 0.3. However, an A+ has value 4.0. Enter a letter grade: B- The numeric value is 2.7.arrow_forward
