I\'ve created this code so far: private void btnCalculate_Click(object sender, EventArgs e) { double principle, // principle rate,       // interest rate amount;     // amount on deposit int year,          // total years entered by user yearCounter;   // counter for each year; used in deposit amount formula // create a header string strOutput = \"Year\\tAmount on Deposit\ \ \"; // get user input principle = Convert.ToDouble(txtPrinciple.Text); rate = Convert.ToDouble(txtInterest.Text); year = Convert.ToInt32(updYear.Text); // change interest rate to decimal equivalent (ie: user enters 5; change to .05) rate /= 100; // Loop from year 1 through the year entered by the user. Calculate amount on deposit for each year. for (yearCounter = 1; yearCounter <= year; ++yearCounter) { // calculate yearly amount using given formula amount = principle * Math.Pow(1 + rate, yearCounter); // build the string that will finally be displayed in the multiline textbox strOutput += yearCounter + \"\\t\" + String.Format(\"{0:C}\", amount) + \"\ \ \"; } // display the string in the multiline textbox txtAnnualAmount.Text = strOutput; } } } However, I\'m trying to increment the years in multiples of 5 instead of 1 in the multiline textbox. How do i do this? Solution All you need is to replace the increment operation for loop from incrementing value by 1 to incrementing value by 5. Modify the for loop code as follows: //Some code goes here for (yearCounter = 1; yearCounter <= year; yearCounter = yearCounter + 5 ) { // Some code goes here } // Some code goes here .

1. I've created this code so far:
private void btnCalculate_Click(object sender, EventArgs e)
{
double principle, // principle
rate,      // interest rate
amount;Â Â Â Â // amount on deposit
int year,         // total years entered by user
yearCounter;Â Â // counter for each year; used in deposit amount formula
// create a header
string strOutput = "YeartAmount on Deposit ";
// get user input
principle = Convert.ToDouble(txtPrinciple.Text);
rate = Convert.ToDouble(txtInterest.Text);
year = Convert.ToInt32(updYear.Text);
// change interest rate to decimal equivalent (ie: user enters 5; change to .05)
rate /= 100;
// Loop from year 1 through the year entered by the user. Calculate amount on deposit for each
year.
for (yearCounter = 1; yearCounter <= year; ++yearCounter)
{
// calculate yearly amount using given formula
amount = principle * Math.Pow(1 + rate, yearCounter);
// build the string that will finally be displayed in the multiline textbox
strOutput += yearCounter + "t" + String.Format("{0:C}", amount) + " ";
}
// display the string in the multiline textbox
txtAnnualAmount.Text = strOutput;
}
}
}
However, I'm trying to increment the years in multiples of 5 instead of 1 in the multiline
textbox. How do i do this?

2. Solution
All you need is to replace the increment operation for loop from incrementing value by 1 to
incrementing value by 5.
Modify the for loop code as follows:
//Some code goes here
for (yearCounter = 1; yearCounter <= year; yearCounter = yearCounter + 5 )
{
// Some code goes here
}
// Some code goes here
