Help with error Run-Time Check Failure #3 - The variable 'rain1' is being used without being initialized.

[cruze36]

here is my code:

#include <iostream>
#include <string>
using namespace std;

int main()
{

string month1, month2, month3;
double rain1, rain2, rain3, avg;

cout << "Enter the first month: " << month1 << "." << endl;
cin >> month1;
cout << "Enter the first month's rainfall:" << rain1 << "."<< endl;
cin >> rain1;

cout << "Enter the second month: " << month2 << "." << endl;
cin >> month2;
cout << "Enter the second month's rainfall:" << rain2 << "." << endl;
cin >> rain2;

cout << "Enter the third month: " << month3 << "." << endl;
cin >> month3;
cout << "Enter the third month's rainfall:" << rain3 << "." << endl;
cin >> rain3;

avg = (rain1 + rain2 + rain3) / 3;

cout << "The average rainfall for " << month1 << ", " << month2 << ", and " << month3;
cout << " is " << avg << " inches."<< endl;
system ("pause");
return 0;
}

ok i have a problem setting setprecision(2) to the value avg?? it tells me that the identifier is undefined!

For example in this statement

cout << "Enter the first month's rainfall:" << rain1 << "."<< endl;

you output rain1 that was not initialized.

Write instead

cout << "Enter the first month's rainfall: ";

And change other similar statements the same way.
