Problem Statement

You are tasked with writing a C$++$ program to determine the interest rate for a loan based on multiple factors and then display an amortization table. The factors influencing the interest rate are the credit score, loan amount, and loan term. The program should calculate the monthly payment and display the amortization schedule, including the monthly interest paid, principal paid, and remaining balance. Interest Rate Determination:

$-$ If the credit score is above $750,$ the base interest rate is $\backslash (3\backslash \%\backslash ).$

$-$ If the credit score is between $650$ and $750,$ the base interest rate is $\backslash (5\backslash \%\backslash ).$

$-$ If the credit score is below $650,$ the base interest rate is $\backslash (7\backslash \%\backslash ).$

$-$ Adjustments to the base interest rate:

$-$ If the loan amount is greater than $\backslash (\backslash$$ $300,000\backslash ),$ add $\backslash (0\mathrm{.}5\backslash \%\backslash )$ to the interest rate.

$-$ If the loan term is greater than $20$ years, add $\backslash (0\mathrm{.}5\backslash \%\backslash )$ to the interest rate.
