Homework SourseWrite a program to compute the amount of money you will have
Write a program to compute the amount of money you will have on an initial amount invested for a number of years at an annual percentage rate of interest. The user also adds a fixed amout to the investment each month. Show a table of the running amount each month (see below). Ask the user for the principal, the annual rate, the number of years and the amount he can afford to add to the investment each month. All dollar amount is to be rounded to two decimal places.
Use the following variable assignments and declarations in your program: You can comment on the variables and list them one per line as follows and place a comment as to what they represent.
double
Principal, // holds principal
AnnRate, // holds the annual interest rate
MthlyDepositAmt, // to hold the monthly deposit amount
MthlyInterestRate, // to hold the monthly interest rate
NewAmount, // holds the new amount each month
InterestAmt; // holds the interest amount
int Years, // holds the years
Months; // holds the month number
get Principal // ask for the principal
get Years // ask for the number of years
get MthlyDepositAmt // ask for the monthly deposit amount
use the following statement before the loop to set the decimal precision to 2 - display the amounts rounded to two decimal places.
cout <<setprecision(2)<<fixed;
#include<iomanip> <= you must include this library
use the following statement in your loop to display the amounts in columns of 10 wide
cout <<setw(10)<<Months<<setw(10)<<InterestAmt<<setw(10)<<MthlyDepositAmt<<setw(10)<<NewAmount<<endl;
What is the principal? 500
What is the % annual rate? 12
How many years? 4
How much would you like to put away each month? 50
