Question

求大神帮我写下这个C语言程序 把源代码回复给我 谢谢了！

1. The dollar change remaining after an amount paid is used to pay a
restaurant bill of amount check can be calculated using the following C
statements:
/* determine the amount of the change */
change = (paid - check) * 100;
/* determine the number of dollars in the change */
dollars = change / 100;
…
(1). Using the previous statements as a starting point, write a C program
that calculates the number of dollar bills(100 cents), quarters coins(25
cents), dimes coins (10 cents), nickels coins (5 cents), and pennies coins (1
cents) in the change when $10 is used to pay a bill of $6.07.
(2) Using the C program to calculate the change when a check of $12.36
is paid using a $20 bill.
