[SOLVED] I Need Help With This C++ Problem

Question

Students will calculate the balance on a bank credit card that increases at a rate of 2% every month. The initial balance starts at $50.

Use a while loop to repeat the increase until the balance reaches $100 or more. By implementing a counter; your program should count

the number of months it takes to reach $100 and report it at the end of your program.

#include <iostream>
using namespace std;

int main(){
int accumulate = 100;
int balance;
double rate = 0.02;
int time = 0;
double totalbalance = 50;

cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(2);

while (balance<accumulate)
{
balance += balance + (balance*2/100);
balance -= 50;
time += 1;
}

cout << "This program tells you how long it takes to accumulate a debt of

Answer 1

I think <balance> is better be a `double` cause a 2% increment to an integer *may not* result as expected.

Why you decrement <balance> inside the while...loop though?

Answer 2

Alright Good Job! 👍

Answer 3

#include <iostream>
using namespace std;

int main() {
// your account's balance
auto balance = 2452.4;
// price for each notebook
auto price = 259.99;

// Task: calculate the number of notebooks you can afford and output it.
// Hint: use an integer to store the result.

// Task: calculate the amount left over on your account after the purchase and output it on a new line.
// Hint: calculate the total price of the purchase, then substract it from the balance.

}

Answer 4

Thanks for the answer. At the end, I figured it out.

#include <iostream>
using namespace std;

int main(){
int accumulate = 100;
double balance = 50;
double rate = 0.02;
int time = 0;

cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(2);

while (balance<accumulate)
{
balance = balance + (balance*0.02);
time++;
}

cout << "This program tells you how long it takes to accumulate a debt of quot;<< accumulate << ", starting with" << endl;
cout << "an initial balance of $50 owed." << endl;
cout << "The interest rate is 2%" <<" per month."<<endl;
cout << "After " << time << " months," << endl;
cout << "your balance due will be quot; << balance << endl;

return balance;
}
