Why my program not give proper output for Final Amount? (SOLVED)

Question

Write a program to create a structure called BankDeposit(). Structure members are amt (amount to deposit in bank), tenure (No. of years the deposit to be maintained). Create another structure called Date(), structure members are int date, int month, int year. Enter DOB of person, Date of deposit using Date structure variables. Calculate present age of the person. If the person is senior citizen (age >=60 yrs) then rate of interest is 9%, else 8%. Calculate the total amount that person receives after date of maturity (=date of deposit+ tenure).
Structure BankDeposit ()
{
Int amt;
Int tenure;
};
Structure Dates ()
{
Int date;
Int month;
Int year;
};
Input1:
Amt=1000 rs.
Tenure=2 years
DOB= 01/01/1960
Output1:
Age= 61 years
Interest=9%=0.09
Final amount=amt+(amt*interest*tenure)
=1180 rs.
Input2:
Amt=1000 rs.
Tenure=2 years
DOB= 01/01/2000
Output2:
Age= 21 years
Interest=8%=0.08
Final amount=1160 rs.

Answer 1

Integers can only store whole numbers. Whenever you want to store fractions such as 0.09, you need to use either float or double as the datatype.
