two-dimensional array

I can't understand that how can we take two values in array and get average....

a program that uses a two-dimensional array to store the highest and lowest temperatures read from the user for each

month of the year. The program should output the following:

1. Average high temperature for the year

2. Average low temperature for the year

3. Highest high temperature for the year

4. Lowest low temperature for the year

please help me.

Try this:

using System;

class Program

{

static void Main()

{

string[] months =

{

"January",

"February",

"March",

"April",

"May",

"June",

"July",

"August",

"September",

"October",

"November",

"December"

};

double[,] temperatures = new double[12, 2];

for(int i = 0; i < 12; i++)

{

Console.WriteLine("Input temperatures for {0}", months[i]);

Console.Write(" Highest : ");

temperatures[i, 0] = double.Parse(Console.ReadLine());

Console.Write(" Lowest : ");

temperatures[i, 1] = double.Parse(Console.ReadLine());

Console.WriteLine();

}

// work out average high temperature

double total = 0;

for(int i = 0; i < 12; i++) total += temperatures[i, 0];

Console.WriteLine ("Average high temperature = {0:F2}", total/12);

// work out average low temperature

total = 0;

for(int i = 0; i < 12; i++) total += temperatures[i, 1];

Console.WriteLine ("Average low temperature = {0:F2}", total/12);

// work out highest high temperature

double highest = temperatures[0,0];

for(int i = 1; i < 12; i++)

if (highest < temperatures[i, 0]) highest = temperatures[i, 0];

Console.WriteLine ("Highest high temperature = {0}", highest);

// work out lowest low temperature

double lowest = temperatures[0,1];

for(int i = 1; i < 12; i++)

if (lowest > temperatures[i, 1]) lowest = temperatures[i, 1];

Console.WriteLine ("Lowest low temperature = {0}", lowest);

Console.ReadKey();

}
