4.1. Part b Write a program that prompts the user for a count of quarters, dimes, nickels and pennies. The program must output the total amount in dollars and cents. For example: Enter number of quarters: 6 Enter number of dimes: 2 Enter number of nickels: @ Enter number of pennies: 1 You have $1.71 in coins. Note: you must ensure that the output properly shows two decimal places (e.g. $1.50 vs. $1.5) and, if any of the counts are negative, provide an error message after inputting all counts (supplied as a constant), 4.2. Part c Write a program that prompts the user for a dollar amount. The program outputs the fewest number of coins needed. For example: Enter total amount: $1.71 You have 6 quarters, 2 dimes, e nickels, and 1 penny. Note: due to numerical error you must convert the initial input to an integer - the number of pennies before performing any calculations. Once computed as a double (i.e. 171.0), you have been supplied a method (convertToInt, which you MUST use) to convert the double to an integer (i.e. 171). Only then proceed to compute number of coins
