Analysis
There is a requirement to develop a program that would be able to estimate loan by making
some entries by the user like tenure as well as amount of loan with its number. The program
would also be able to demonstrate graphically monthly expense including the rate of interest.
Thus, the program so developed will take some entries from the user in the form of numerical
number i.e. from 0 to 9 and will also make user to enter a key, then it will be further directed
to enter some more values including loan tenure which is also of numerical form only, the
user would also be asked to enter any letter and verify loan tenure and monthly payment
including interest.
Design
The major step that is required to solve the current problem is as follows:
Step1: Assign letters to the associated number i.e. 0 to 9.
Step2: Take input from users:
 If a user selects and enter key, the program would display the assigned letter.
 If a user selects and click on any symbol then an error message would be generated,
display to the user.
