Then initialize the variable.

I believe I did ?

{
const decimal r = 0.05m;
decimal p = 1000;
int n = 1;
string myString;



for (n = 1; n <= 5; n++)
{
p = p * (1 + r);
myString = p.ToString("C") + "\n";

}

MessageBox.Show(myString, "Compound Interest", MessageBoxButtons.OK, MessageBoxIcon.Information);

}

you declared it, not initialized it.

string myString = "";

it only gives me the last iteration now

look very closely at your code. in particular, how are you assigning the string? use a debugger or log statement if you must.

This.

Hint: Look inside your loop and take a close look at your assignment operator.
