Denomination breakup

ISC 2010 Computer Science Practical, Question 1 · Number programs

The question

A bank intends to design a program to display the denomination of an input amount of upto five digits. The available denomination with the bank are of rupees 1000, 500, 100, 50, 20, 10, 5, 2, 1.

Design a program to accept the amount from the user and display the breakup in descending order of denomination, (i.e. preference shoud be given to the highest denomination available) along with the total number of notes. [Note: Only the denominations used should be displayed.] Also print the amount in words according to the digits.

Example 1
INPUT:  14856
OUTPUT: ONE FOUR EIGHT FIVE SIX
        DENOMINATION
        1000    x   14          =   14000
        500     x   1           =     500
        100     x   3           =     300
        50      x   1           =      50
        5       x   1           =       5
        1       x   1           =       1
        TOTAL                   =   14586
        TOTAL NUMBER OF NOTES   =      21
