 Program Make Change

// ****************************************************
// Program Make Change: Given any amount of change
// expressed in cents, this program computes the number
// of half-dollars, quarters, dimes, nickels, and
// pennies to be returned, returning as many
// half-dollars as possible, then quarters, dimes,
// nickels, and pennies in that order.
