Help with inititalizing a variable in a for loop

[Jose94ji]

It says total rain is not initialized, but if I set it to 0 then it will be reset every time it loops around how can I fix this?

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

struct months
{
	float rain;
	float high;
	float low;
	float average;
};


int main()
{
	const int month= 12;
	months total[month];

	string monthName[month]={"January","February","March","April","May","June","July","August",
 "September","October","November","December"};

	for(int i=0; i<12; i++){;
		cout << monthName[i] << endl;
		cout << endl;
		cout << "Enter total rain for this month: ";
		cin >> total[i].rain;
		cout << endl;
		cout << "Enter the highest temperature for this month: ";
		cin >> total[i].high;
		while(total[i].high<-100||total[i].high>140)
	{
		cout << endl;
		cout<<"Invalid entry-must be between -100 through 140\n";
		cout<<"high temperature: ";
		cin>>total[i].high;
		cout << endl;
 }
		cout << endl;
		cout << "Enter the lowest temperature for this month: ";
		cin >> total[i].low;
		while(total[i].low<-100||total[i].low>140)
 {
	 cout << endl;
	 cout<<"Invalid entry-must be between -100 through 140\n";
	 cout<<"high temperature: ";
	 cin>>total[i].low;
	 cout << endl;
 }
		cout << endl;
		cout << endl;
		total[i].average = (total[i].high+total[i].low)/2;
		cout <<"The avearge temperature of this month is: " << total[i].average;
		cout << endl;
		cout << endl;
int totalRain;
totalRain += total[i].rain;
if(i==11){
	cout << totalRain;
}

		}


	
	system("PAUSE");
	return 0;
}

Does it give error at line 56? Line 55 should be int totalRain=0; (need to initialize it), and you probably want it outside the for loop

[Locien]

Declare and initialize it outside your for loop?

[Chervil]

This could be moved outside the loop too:

if(i==11){
	cout << totalRain;
}

Move it after the end of the for loop, and you can just put:
cout << totalRain;

(though to be fair, some text to label the value would be useful too).
