Thread: Arrays Dev-c++ (please helps)

Hey can someone please help me with my project? I attached the instructions + .cpp file , I can't seem to get it to work correctly.



Thank you!!

What function calls? and I used arrays cause it is the name of the project >_<

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]; 
      
          
        
    
   //telling the user the average high temperature
    cout << "Average high temperature:"<<averageHigh<< endl;
   
   //telling the user the average low temperature
    cout << "Average low temperature:"<<averageLow<< endl;
   
    //telling the user the highest temperature
    cout << "Highest temperature:"<<indexHighTemp<< endl;
    
    //telling the user the lowest temperature
    cout <<"Lowest temperature:"<<indexLowTemp<< endl;
    cout<<"Name"<< 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 sumh = 0;
    
    for(int i=0; i<12; i++)
        sumh += array[i][0];
    return sumh/12.0;
}
//does the math for the average low temperatures, also contains a for looop
double averageLow(int array[][2])
{
    int suml = 0;
    
    for(int i=0; i<12; i++)
        suml += array[i][1];
    return sum1/12.0;
}
//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];
            
        }
    }
    return highTemp;
}

int indexLowTemp(int array[][2])
{
    int index = 0;
    int lowTemp = array[0][1];     
    for(int i=1; i<12; i++)
    {
        if(array[i][1] < lowTemp)
        {
            lowTemp = array[i][1];
            index = i;
        }
    }
    return lowTemp;
}

What function calls????? What are these if not function calls?
You're doing it wrong - you're printing the address of the function (or if you'd used Visual Studio 2005 or another compiler, you'd get a compile error because that isn't standard!)!

I can't use vector stuff cause I haven't learned it, and my teacher calls the "function calls" output to screen?? so the out put to screen is function calls?

A function call is when you call a function - simple enough

Code:

int foo()
{
	return 6;
}

int main()
{
	int myint = foo(); // Calls function - aka function call.
	cout << myint; // Prints 6 to screen.
	cout << foo(); // Calls function - aka function call. Prints 6 to screen.
	cout << foo; // Prints the function ADDRESS. Where the function is located in the memory (if it compiles at all)!
}

But aren't they something like this? not sure if i've ever seen them the other way

Code:

    getData(array[i][0],array[i][1]); 
	averageHigh(sumh); 
	averageLow(suml); 
	indexHighTemp(highTemp); 
	indexLowTemp(lowTemp);

No, I'm not majoring in Programing I just had to take the class..

I did a function program before but not with arrays

Is it something like this?

Code:

int main()
{
    int months[12][2]; 
        
    getData(array[i][0],array[i][1]); 
	averageHigh(sumh); 
	averageLow(suml); 
	indexHighTemp(highTemp); 
	indexLowTemp(lowTemp); 
   
        
    
   //telling the user the average high temperature
    cout << "Average high temperature:"<<averageHigh[sumh]<< endl;
   
   //telling the user the average low temperature
    cout << "Average low temperature:"<<averageLow[suml]<< endl;
   
    //telling the user the highest temperature
    cout << "Highest temperature:"<<indexHighTemp[highTemp]<< endl;
    
    //telling the user the lowest temperature
    cout <<"Lowest temperature:"<<indexLowTemp[lowTemp]<< endl;
    cout<<"Name"<< endl;
             
    getch ();
    return 0;
}

I don't understand the tutorial...
