// Program to calculate compound interest for the provided principle amount & time by following certain criteria.
|
|
// You are builing an interest calculation. Following are the rules:
|
|
// 1. If deposit = 1yr : Interest = 5%
|
|
// 2. If deposit = Greater than 1 yr and less than 3yr : Interest = 5.5%
|
|
// 3. If deposit = Greater than 3 yr and less than 5yr : Interest = 6%
|
|
// 4. If deposit = Greater than 5 yr : Interest = 6.5%
|
|
// 5. If age = Less than 18 : + 1%
|
|
// 6. If age = Less than 60 : + 1.5%
|
|
// Input from user for Principle Amount & Tenture (time period).
|
|
// Output Principle + Interest.
