Question
To prevent a dollar amount from being altered, most computerized check-writing systems employ a technique called check protection. Checks designed for imprinting by computer contain a fixed number of spaces in which the computer may print an amount. Suppose a paycheck contains nine blank spaces in which the computer is supposed to print the amount of a weekly paycheck. If the amount is large, then all nine of those spaces will be filled--for example:
1, 230.60 (check amount)
-----------
123456789 (position numbers)
On the other hand, if the amount is less than $1000, then several of the spaces will ordinarily be left blank ---- for example: 99.87 ----------- 123456789 Contains three blank spaces. If the check is printed with blank spaces, it is easier for someone to alter the amount of the check. To prevent a check from being altered, many check-writing systems insert leading asterisks to protect the amount as follows:
****99.87
----------
123456789
Write a program that inputs a dollar amount to be printed on a check and then prints the amount in check-protected format with leading asterisks if necessary. Assume that nine spaces are available for printing an amount. THEN Write a second script that inputs a numeric check amount and writes the word equivalent of the amount. For example, the amount 112.43 should be written as ONE HUNDRED TWELVE and 43/100. ( I need program in HTML/JAVASCRIPT code only please ) Thank you in advance
