error c2664: I am having problem with my code

Hi, I am having trouble with my code.

Could you please tell me why it doesn't compile?

Thanks a lot.

#include<iostream>
#include<iomanip>

using namespace std;
const int N=6;

void ReadData(int x[]);
void Display (int x[]);
float FindAve(int x[]);
void DisplayAbove(int x[], float);
void FindMaxMin(int x[], int& max, int& min);

int main(){
	int a[N];
	//read data into array a
		ReadData(a);
	//Display array a
		Display(a);
	//find and display the average of numbers of array a
		float Average=FindAve(a);
		cout<<"Average= "<<fixed<<setprecision(2)<<Average<<endl;
	//Display data numbers whose value is >= average
		DisplayAbove(a,Average);
	//find and display the maximum and minimum numbers in array a
		int man, min;
		FindMaxMin(a,max,min);
		cout<<"The maximum data is "<<max<<endl;
		cout<<"The minimum data is "<<min<<endl;
	//terminate program
		return 0;
