Can you help with this? Therefore, you may use the following code to determine if a non-numeric or negative numberhas been entered:If the credit score is below 300, display an error message to the user stating that the loancannot be offered and exit the program. Make certain that the error message is displayedfor a long enough duration for the user to read it before the program closes.int num;cout <« "Enter an integer: " <« endl;cin >> num;3. Prompt the user to enter the term of the loan. Valid terms are 10, 15, and 30 years. Anyother numbers should be rejected, and the user should be prompted to re-enter anappropriate value.while (cin.fail() || num < 0){cout <« "You must enter a number, and that number must be positive.Please try again. " << endl;cin.clear();cin.ignore(numeric_limits: : max(), '\n');cin >> num;4. Once the inputs have been entered and validated, your program must generate an interestrate to be used in the loan calculation.а.Create an enum to represent the possible credit ratings: EXCELLENT, GOOD,FAIR, and BAD.}b. Assign the appropriate enum to the customer based on the ranges listed in Table 1The reason that this code works is due to the behavior of "cin." Whenever cin tries toabove. I recommend using if-statements for this.read a letter (or any non-numeric character) into a variable that is designed to hold a number, cinenters a fail state, which can produce erroneous results and potentially even cause your programto crash. Therefore, you must trap for non-numeric data whenever the program is expecting anumber. One way to trap for this error is to check if "cin" has entered the fail state using the"cin.fail()" function. If it has, then you first have to clear cin out of its fail state using thecin.clear() function. Afterwards, you can issue the "ignore" command which flushes anyremaining garbage out of the input stream (aka “cin buffer"). Finally, you can prompt the user tore-enter a correct value. Note that the code above is not especially informative. That is, itproduces a single generic error message to the user such that the user may not realize what he didwrong to cause the problem. Therefore, feel free to tweak it as necessary in order to customizeyour error messages. One other point of interest is that the code above doesn't allow the user anopportunity to end the program if he can't provide an acceptable value. It just continues to loopuntil an acceptable value is entered. In real life, you would definitely want to allow your user ameans of escape. In this assignment, however, continuing to prompt the user for a valid valueuntil one is entered is fine. Later in the course, we'll learn more sophisticated ways of errorchecking when we discuss exception handling.c. Using a SWITCH statement with the enum values as cases, assign an interest ratebased on the customer's credit rating.i. Within each case, use a random number generator to create an interest ratefor each category based on the ranges listed in Table 2 above. Because therandom number generator that you have been taught generates only integervalues, you will need to generate a number in the hundreds and divide thatnumber by 100 to get a result within the valid range for interest rates. Becareful with integer division here. Remember that an int divided by an intequals an int (i.e. int/int=int). To arrive at a double, you must make eitherthe numerator or denominator a double to generate an interest rate with adecimal portion.5. To perform the calculation for a monthly payment, create a function called CalcPaymentthat receives the principle, interest rate, and number of years as parameters. The functionshould return the monthly payment that is calculated.Your program should check for invalid data such as non-numeric and non-positive entries forprinciple, credit score, and term. Use proper indentation and style, meaningful identifiers, andappropriate comments.Good luck on this assignment! Have fun with it, and as always, let me know if you haveany questions.To give you an idea of the general criteria that will be used for grading, here is a checklist thatyou might find helpful:General notes about error checkingAs in all applications, you should design your code to be robust enough to handle anything that auser may enter. In this program, you will prompt the user to enter three numbers: a principleamount, a credit score, and a number of years (i.e. term). Because users can make mistakes, youneed to make sure that they enter numbers for these inputs (as opposed letters or othercharacters) and that any numbers entered are reasonable. For example, what if a user entered-10000 as the principle amount? Or negative years? What is a negative year anyway? It justdoesn't make sense.Compiles and Executes without crashingStyle:No global variablesCode is modularUse of enum for credit rating C++ PROGRAMMING ASSIGNMENTS INSTRUCTIONSFormulasC++ Programming Assignment 1Loan Payment CalculatorPayment Calculator[Adapted from Wittwer, J.W., "Amortization Calculation," From Vertex42.com, Nov 11, 2008.]The purpose of this assignment is to get you back into programming and give you some practicewith some C+ topics that you should be familiar with from CSIS 111 as well as a new concept,random number generation.The formula to calculate the monthly payment for a fixed interest rate loan is as follows:r(1+r)"A = P(1 + r)* – 1Overview:whereYou are working as a computer programmer for a mortgage company that provides loans toconsumers for residential housing.

The interest rates offered to customers arebased on the customer's credit score. Credit scores are classified into the following categories:Example: What would the monthly payment be on a 15-year, $100,000 loan with a 4.50%annual interest rate?Table 1: Credit Score CategoriesRatingExcellentGoodRangeP = $100,000r = 4.50% per year / 12 months = 0.375% (or 0.00375) per periodn = 15 years * 12 months = 180 total periods720-850690-719Fair630-689Bad300-629A = 100,000 * (.00375 * (1+ .00375)180)/((1+.00375)180 – 1)The program should initially prompt the user (the loan officer) for the principle of the loan (i.e.the amount that is being borrowed). It should then ask him or her to enter the customer's creditscore. Based on the customer's credit score, the program will randomly generate an interest ratebased on the following ranges:Using these numbers in the formula above yields a monthly payment of $764.99.Requirements:Table 2: Interest Rate AssignmentsRatingExcellentInterest RateTo receive credit for this assignment, certain programming features must be implemented in sucha way as to demonstrate your knowledge of random number generation, use of enums, properformatting of output, input error checking, switch statements, and if statements.2.75% - 4.00%Good4.01% - 6.50%Fair6.51% - 8.75%Bad8.76% - 10.50%The final input should be the number of years that the loan will be outstanding. Because thecompany only offers three different terms ( 10-, 15-, and 30-year loans), the program shouldensure that no other terms are entered.1. Start your program by prompting the user to enter a principle amount. The data type ofthis number should be a double. The amount must be positive and it must also be anumeric value. For example, when prompted to enter a number, if the user enters "abc,"the program will not be able to process the loan appropriately. Likewise, if the user enters-100000, the program will again produce erroneous results.2. Prompt the user to enter the customer's credit score. Again, appropriate error checking isessential here. In addition to ensuring that values are numeric and positive, you must alsoensure that the credit score entered does not exceed 850. If a non-numeric, negative, orscore that exceeds 850 is entered, prompt the user to re-enter the score.
