# Give Out Coins for Change Calculation

## How can we calculate the amount of change for any value from 1 cent to 99 cents?

When the amount is 86 cents, what would be the output?

## Calculating Change:

When the amount is 86 cents, it can be broken down as 3 quarter(s), 1 dime(s), and 1 penny (pennies).

In order to calculate the amount of change from 1 cent to 99 cents, we can utilize a program that determines what coins to give out for a specific amount. The program uses coin denominations of 25 cents for quarters, 10 cents for dimes, and 1 cent for pennies.

The main function of the program is **computeCoin(int coinValue, int& number, int& amountLeft)**, which calculates the maximum number of coins of a particular denomination that can be obtained from the remaining amount. It then decreases the amount left by the value of the coins used.

For example, when the value of the variable amountLeft is 86 cents, calling the function with coinValue 25 would set the value of number to 3 (as 3 quarters can be taken from 86 cents) and reduce the amountLeft to 11 cents.

In the program, the user is prompted to enter the number of cents, and the program ensures that only valid input values from 1 to 99 are accepted. If an invalid number is entered, an error message is displayed, and the user is prompted to re-enter the value.

It is recommended to test the program with various values to ensure that it provides the correct output before final submission.
