Question

in C#

Assignment #2: Millionaire Write a program that takes as input the amount of money deposited as well as the current rate of interest as a percent. The program should then determine the number of years it will take before becoming a millionaire. Make sure that you include the following error checking to ensure that both the Principal and interest rate are positive real numbers. Hints: • Ensure that Rate of Interest is a decimal (divide by 100) • The initial balance = Principal invested Yearly interest = current balance * Rate of Interest • New balance previous balance + yearly interest

Answer 1

Here I am providing the answer for the above question:

Code:

using System;

class Years
{
static void Main()
{
int percentage;
double princialAmount,rate;
Console.WriteLine("Enter principal amount:");
princialAmount = double.Parse(Console.ReadLine());
Console.WriteLine("Enter interest rate as percentage:");
percentage = Convert.ToInt32(Console.ReadLine());
//finding rate by dividing percentage by 100.
rate=percentage/100.0;
  
int years=0;
double yearlyInterest,newBalance=princialAmount,previousBalence=princialAmount;
while(newBalance<=1000000) //calculating number of years, stoping the loop if it is >100000(1 million)
{
yearlyInterest=newBalance*rate;
newBalance=previousBalence+yearlyInterest;
years++;
previousBalence=newBalance;
}
Console.WriteLine("No of years for becoming millionaire:");
Console.WriteLine(years);
}
}

Screenshot:

using System; class Years static void Main() int percentage; double princialAmount,rate; Console.WriteLine("Enter principal amount:"); princialAmount = double.Parse(Console.ReadLine()); Console.WriteLine("Enter interest rate as percentage: "); percentage = Convert.ToInt32(Console.ReadLine(); //finding rate by dividing percentage by 100. rate=percentage/100.0; int years=0; double yearlyInterest, newBalance=princialAmount,previousBalence=princialAmount; while(newBalance<=1000000) //calculating number of years, stoping the loop if it is >100000(1 million), yearlyInterest=newBalance rate; newBalance=previousBalence+yearlyInterest; years++; previousBalence=newBalance; Console.WriteLine("No of years for becoming millionaire: "); Console.WriteLine(years);

Output:

Enter principal amount: 50000 Enter interest rate as percentage: 50 No of years for becoming millionaire:

Hoping that the above answer will help you...Thank you...
