I can't get the value of interest_rate in the if else [closed]

Variable 'interest_rate' might not have been initialized Write a program Loan Calculator that input customer name, principal loan, term or period. Compute the interest per annum, total interest, the total payable loan and the monthly amortization.

Rate     Interest Rate
1-3 year 6.500%
5 year   7.270%
10 year  8.035%
15 year  8.585%
20 year  8.800%
25 year  9.050%
