    It would help if you asked a specific question. Like what you don't understand about functions.

    It would also help to get a grasp of the language before you use it. You don't drive a car before you know how to operate it!

    is this correct?

    Code:
    #include <iostream>
    #include <conio.h>
    
    using namespace std;
    //the function prototypes 
    void getData(int array[][2]);
    double averageHigh(int array[][2]);
    double averageLow(int array[][2]);
    int indexHighTemp(int array[][2]);
    int indexLowTemp(int array[][2]);
    
    int main()
    {
        int months[12][2]; 
        
        getData(months);
       //telling the user the average high temperature
        cout << "Average high temperature:"
                  << averageHigh(months) << endl;
       
       //telling the user the average low temperature
        cout << "Average low temperature:"
                  << averageLow(months) << endl;
       
        //telling the user the highest temperature
        cout << "Highest temperature:"
                  << indexHighTemp(months)  << endl;
        
        //telling the user the lowest temperature
        cout << "Lowest temperature:"
                  << indexLowTemp(months)  << endl;
                
        getch ();
        return 0;
    }
    
    void getData(int array[][2])
    {
         /* asks the user to input the highest and lowest temperatures 
         and contains the for loop to store it and a counter.*/
        
        cout << "Please enter highest temperatures for each month." << endl;
        for(int i=0; i<12; i++)
            cin >> array[i][0];
        
       cout << "Please enter lowest temperatures for each month." << endl;
        for(int i=0; i<12; i++)
           cin >> array[i][1];      
    }
    //does the math for the average high temperatures 
    double averageHigh(int array[][2])
    {
        int sumHigh = 0;
        
        for(int i=0; i<12; i++)
            sumHigh += array[i][0];
    
        return sumHigh/12.0;
    }
    //does the math for the average low temperatures, also contains a for looop
    double averageLow(int array[][2])
    {
        int sumLow = 0;
        
        for(int i=0; i<12; i++)
            sumLow += array[i][1];
    
        return sumLow/12.0;
    }
    //a nested for loop to find the highest and lowest temperature
    int indexHighTemp(int array[][2])
    {
        int highTemp = 0; 
        
        for(int i=0; i<12; i++)
        {
            if(array[i][0] > highTemp)
            {
                highTemp = array[i][0];
                
            }
        }
        getch();
        return highTemp;
    }
    
    int indexLowTemp(int array[][2])
    {
        int lowTemp = array[0][1];     
        for(int i=1; i<12; i++)
        {
            if(array[i][1] < lowTemp)
            {
                lowTemp = array[i][1];
                
            }
        }
        getch();
        return lowTemp;
    }

    Yes, this looks correct. Does it work?
