Interest Rate + Principal Calculator

Create a program that will that will calculate Yearly Interest or Compound Interest on a starting principal.

Accept user input in dollars$ in main(). Program should not run if dollar amount > 0. Prompt user and exit the program.)

Your program will have a menu.

Yearly Interest Function: Create a function that accepts 3 arguments.

1 argument will represent savings

1 argument will represent years

1 argument will represent interest rate.

Function will output each year\'s principal value. (Output will not be one singular value, but each year’s value.) So if years == 10, there will be 10 outputs.

Compound Interest Function: Create a function that accepts 4 arguments. (Research on compound interest is required.)

1 argument will represent savings

1 argument will represent years

1 argument will represent interest rate.

1 argument will represent numbers of times it is compounded.

Please attach snipping photos of source code and output from each function.

Sample:

Please enter $ in savings.

3334

Please enter number of years.

3

Please enter number of years.

1.0

Year 1 = $3367.34

Year 2 = $3401.01

Year 3 = $3435.02

Sample:

Please enter $ in savings

3334

Please enter number of years

1

Please enter interest rate

1.0

Number of times compounded

3

Principle Compounded 1 = $3367.34

Principle Compounded 2 = $3401.01

Principle Compounded 3 = $3435.02

Solution

HI, Friend, You have not mentioned the details about how to calculate YearlyInterest and CompoundCAlculator.

I have coded every thing except the logic to calculate interest/amount.

Please replace/implement with actual code in my function or give me details about those formula.

Please find my program.

#include <iostream>
#include <cmath>
using namespace std;

// function declaration
void displayMenu();
void YearlyInterestCalculator(double amount , int year, double rate);
void CompoundInterestCalculator(double amount, int year, int rate, int times);

int main(){

   // variable declaration
   double amount, rate;
   int year, times, option;

   // calling displayMenu function
   displayMenu();

   cin>>option;

   if(option == 1){
       cout<<\"Please enter $ in savings.\"<<endl;
       cin>>amount;
       // validating amount
       while(amount < 0){
           cout<<\"Please enter $ in savings.\"<<endl;
           cin>>amount;
       }
       cout<<\"Please enter number of years.\"<<endl;
       cin>>year;
       cout<<\"Please enter interest rate.\"<<endl;
       cin>>rate;

       // calling function
       YearlyInterestCalculator(amount, year, rate);
   }
   else if(option == 2){

       cout<<\"Please enter $ in savings.\"<<endl;
       cin>>amount;
       // validating amount
       while(amount < 0){
           cout<<\"Please enter $ in savings.\"<<endl;
           cin>>amount;
       }
       cout<<\"Please enter number of years.\"<<endl;
       cin>>year;
       cout<<\"Please enter interest rate.\"<<endl;
       cin>>rate;
       cout<<\"Number of times compounded.\"<<endl;
       cin>>times;

       // calling function
       CompoundInterestCalculator(amount, year, rate, times);

   }
}

// function definations

void displayMenu(){
   cout<<\"**************************************\"<<endl;
   cout<<\"* Main Menu: *\"<<endl;
   cout<<\"* Enter # to run program or Quit *\"<<endl;
   cout<<\"* 1) Yearly Interest Calculator *\"<<endl;   
   cout<<\"* 2) Compound Interest Calculator *\"<<endl;
   cout<<\"* 3) Quit *\"<<endl;
   cout<<\"**************************************\"<<endl;
}

// TODO: please replace with correct formula
void YearlyInterestCalculator(double amount , int year, double rate){

   for(int i=1; i<=year; i++){
       double interest = (amount*year*rate)/100.0;
       amount = amount + interest;
       cout<<\"Year \"<<i<<\" = $\"<<amount<<endl;
   }
}

// TODO : no idea about formula
void CompoundInterestCalculator(double amount, int year, int rate, int times){

}

Please let me know in case of any help
