In my Computer science class we need to create a program that looks like this.

I am confused as to why the interest rate raises 0.02 then raises 0.01 and back to raising 0.02? How can I set this interval ?

Also can you assist me in how to find the total interest rate added (book page/website ok)

int year = 1;
double interest = 1.25;
double total = 100.00;
double tot;
cout << fixed << showpoint << setprecision(2);

while (year <= 10)
{
total = total + interest;
cout << "Year " << year << " adds " << interest << " for a total of " << total << ".\n";
year = year + 1;
interest = interest + 0.02;
}
tot = interest + interest;

cout << "\n" << "Total Interest credited was " << tot << ".\n" << endl;
cout << "Completed Part 4." << endl << endl;
system("pause");
return 0;
}

`RATE = 1.25;`
`interest = total * (RATE / 100);`
