Here is Something for you a easy One.

Code:

struct CalculateRain
{
	double rain;
	char *Month;

};
int main(int argc, char **argv)
{
CalculateRain MyRainArr[3];
double Averagerain =0;
	for(int i=0;i<3;i++)
	{
		cout<<"Enter The Month"<<endl;
		MyRainArr[i].Month = new char[255];
		cin>>MyRainArr[i].Month;
		cout<<"Enter The rain Now"<<endl;
		cin>>MyRainArr[i].rain;
	}
	cout<< "Hre is your Month and rain"<<endl;
	for(i=0;i<3;i++)
	{
		cout<<MyRainArr[i].Month<<" "<<MyRainArr[i].rain<<endl;
		
	}
	cout<<"Average rain is"<<endl;
	for(i=0;i<3;i++)
	{
		Averagerain+=MyRainArr[i].rain;
	}
	cout<<"Average Rain is "<< Averagerain/i;

	for(i=0;i<3;i++)
	{
		delete [] MyRainArr[i].Month;
	}
  return 0;
}

Now i think Minimaum and maximum rain Month you can calculate with your Self.if Still Problem Please Let us Know

 

Anyway, thanks!
I'll check it and will post result soon...
