function help

[thebrainmore]

could someone help with my average and sort functions in this program



[code]#include <iostream.h>


//funtion prototypes
int FindLowNum(int [], int );
int FindHighNum(int [], int);
int average(int[] , int , double );
void sorting(int [], int);

//main function
void main()
{

int A[10];
int i;
double avg;

cout << "Enter Numbers Please:\n";

for (int i=0;i<10;i++)
{
cin>>A[i];
}


for (i=0;i<10;i++)
cout<< A[i]<<' '<<endl;


cout << "the lowest value is :"<<FindLowNum( A, i)<<endl;

cout << "the highest value is :"<<FindHighNum (A, i);

cout << "the average value is :"<<average (avg);


cout<< A[i]<<' '<< sorting (A, size);

}


//function to find the lowest number
int FindLowNum(int array[], int size)
{
int lowest_so_far = array[0];
for (int i=1; i<size; i++)
{
if (array[i]<lowest_so_fa r)
lowest_so_far = array[i];
}
return lowest_so_far;

}

//funtion to find the highest number
int FindHighNum(int array[], int size)
{
int highest_so_far = array[0];
for (int i=1; i<size; i++)
{
if (array[i]>highest_so_far )
highest_so_far = array[i];
}
return highest_so_far;

}

//function to return the average
int average(int num[], int size, double avg)
{
for(int i=0; i<size; i++)
{
avg = (avg + num[i]);
}
avg = avg / size;


return avg;
}


//function to sort numbers
void sorting(int num[], int size)


int higher=0;
int highest=0;


for(i = 1; i <= size, i++)
{


if(num[] > highest)
highest = num[];
else if (num[] >= higher && num[] < highest)
higher = num;

size += 1;
}

What is the third parameter for in the average function? The function should be something like this

int average(int num[], int size) {
       int sum = 0; 
       for(int i=0; i<size; i++) {
           sum = sum + num[i];
        }
       avg = sum / (double)size;
       return avg;
}

your sort function is a mess. You need to look at a sorting tutorial
