- True or False 3. Variable names can have spaces in themuppose you have a certain amount of money in a savings account that earns compoundmonthly interest, and you want to calculate the amount that you will have after a specificnumber of months. The formula, which is known as the future value formula, is:F=P×(1+i)tThe terms in the formula are as follows:o F is the future value of the account after the specified time period.o P is the present value of the account.o i is the monthly interest rate.o t is the number of months.Write a program that prompts the user to enter the account’s present value, monthlyinterest rate, and the number of months that the money will be left in the account. Theprogram should pass these values to a function named futureValue that returns thefuture value of the account, after the specified number of months. The program shoulddisplay the account’s future value. i attached the screenshot of the output so the output should look like that. the coding should be in c++Please add the purpose, parameter, and return value of this code. Write after the “:” to show what the purpose of this code. Def print_35_stars(: Purpose: Parameter(s): Return Value: Print('*****) Print('*****) Print('*****) Print(******) Print(******) Print ('*****) Print('******)
