This is a programming assignment question for C++. I am new to programming and am having trouble. The question is in bold.

Develop a calculator to display the numbers of US dollar ($) bills, when a user inputs the total amount of money as an integer. For example, suppose that the input is 487. So the program displays

$487 is $100 Bills 4 $20 Bills 4 $10 Bills 0 $5 Bills 1 $1 Bills 2 Of course, there are many other combinations. You have to develop a program to calculate the result so that the number of bills is minimum. In the above case, 11 (4 + 4 + 1 + 2) is the minimum. If you have more $20 bills, then the number is increased.

Develop a calculator to display the numbers of Day, Hour, Minute, and Second, when a user inputs the total amount of time in seconds. For example, suppose that the input is 239,782 seconds. The program displays: 239782 seconds are 2 Days 18 Hours 36 Minutes 22 Seconds

Note: We are only supposed to use code we have learned thus far and it's only the first week. No if-else, loops, etc.

Please write a description explaining the code so I can further understand.
