error C2664: cannot convert parameter 1 from 'int' to 'int []'

Hello all. I'm so new in C++ Programming that a simple problem seems extremely difficult!! The only thing that I have to do is to calculate the sum, the average, the max and the min of 10 numbers given by the user!! My code is:

Code:

---

#include <iostream>
using namespace std;

int count_sum(int numbers_par[]);
void count_max(int numbers_par[]);
void count_min(int numbers_par[]);

int main()
{
        int numbers[10]={0,0,0,0,0,0,0,0,0,0};
        int sum;
        double average;
       
        cout<<"Enter 10 integers.\n";
        for(int i=0; i<10; i++)
                cin>>numbers[i];

        sum = count_sum(numbers[10]);
       
        average = sum/10.0;
        cout<<"average "<<average<<endl;
       
        count_max(numbers[10]);
       
        count_min(numbers[10]);
        return 0;
}

int count_sum(int numbers_par[])
{
        int sum=0;
        for(int i=0;i<10;i++)
                sum = sum+numbers_par[i];
        cout<<"sum "<<sum<<endl;
        return sum;
}

void count_max(int numbers_par[])
{
        int max=0;
        for(int i=0;i<10;i++)
                if(numbers_par[i]>max)
                        max=numbers_par[i];
        cout<<"max "<<max<<endl;
}

void count_min(int numbers_par[])
{
        int min=numbers_par[0];
        for(int i=0;i<10;i++)
                if(numbers_par[i]<min)
                        min=numbers_par[i];
        cout<<"min "<<min<<endl;
}

But when I try to execute the latter some errors appear, which are:
1. error C2664: 'count_sum' : cannot convert parameter 1 from 'int' to 'int []'
2. error C2664: 'count_max' : cannot convert parameter 1 from 'int' to 'int []'
3. error C2664: 'count_min' : cannot convert parameter 1 from 'int' to 'int []'

Does anybody know how can I recover from all the above errors? Thanks a lot!

You define functions to expect pointers and not integer numbers.
In line:
sum = count_sum(numbers[10]);
you're sending numbers[10] to function, which is 11-th element of array "number", which is also error because it's beyond of array limits.
i would suggest to write function like this:

Code:

---

int count_sum(int numbers_par[], size_t len)
{
        int sum=0;
        for(int i=0;i<len;i++)
                sum = sum+numbers_par[i];
        cout<<"sum "<<sum<<endl;
        return sum;
}

So what do you think I have to do? Can you tell me books for C++ programming. I think my school's notes are not enough! Thanks

But what about the call? Won't I face an other error which has to do with the parameters of the function? Which is the proper way to call those functions? Thans again.

ok. I solve it! Thans

I'm glad you made it yourself. It's the best way to learn.

Exactly. There are so many people on this forum who just don't want to learn and want others to do their homework for them. That's disgusting.
