need 2D array help

[krunk]

This is my code. I am to read in numbers from a file which is my nums.txt.
Then we are to have the user choose what row or colum they would like to work with. I have two different functions for working with a row or column and we are suppose to find the min, max and avg of the given column/row.

I am having my problem on line 50 and 57.
statisticsR(x[i][j]); - which says invalid conversion from 'int' to 'int(*)[200]'
if anyone knows what im doing wrong please help

#include<iostream>
#include<fstream>

using namespace std;
ifstream fin;
#define max1 100
#define max2 200
void display();
int intalize();
int statisticsR (int x[max1][max2]);
int statisticsC (int x[max1][max2]);


int main() {
	
	display();
	
	
	
	return 0;
	
}
int intalize(){
	int i,j;
	int x[max1][max2];
	fin.open("nums.txt");
	if (!fin) cout << "file did not open";
	while(!fin.eof()){
		for(j=0; j<4; j++){
		fin >> x[i][j];
		return x[i][j]; }
	    cout<< endl;
		i++;
}
}

void display(){
	char a, r, c;
	int num, i, j;
   
	cout<< "please enter filename."<<endl;
	intalize();
	cout << "would you like to work with rows or columns?" <<endl;
	cin>>a;
	if(a ==r) {
		cout << "what row?" <<endl;
		cin >>num;
		if(num>100) cout<< "number exceeds the array";
		i=num;
		statisticsR(x[i][j]);
	}
	if (a == c) {
		cout << "what column?" << endl;
		cin >>num;
		if (num>200) cout << "number exceeds the array";
		j=num;
		statisticsC(x[i][j]);
	}
	if (a!=r||a!=c) cout << "please choose again" << endl;
}
int statisticsR (int x[max1][max2]){
	int i, j,max, min, sum=0;
	double avg=0;
	
	for( j=1; j<200;j++){
		if (x[i][j]> x[i][j-1]) max= x[i][j];
		if (x[i][j]< x[i][j-1]) min= x[i][j];
		sum=sum+ x[i][j];
	}
	avg=sum/j;
	cout<< "max: " <<max <<endl;
	cout<< "min: "<< min<< endl;
	cout <<"avg: "<<avg<<endl;
	return avg;
}
int statisticsC (int x[max1][max2]){
	int j, i,max, min, sum=0;
	double avg=0;
	
	for( i=1; i<100;i++){
		if (x[i][j]> x[i-1][j]) max= x[i][j];
		if (x[i][j]< x[i-1][j]) min= x[i][j];
		sum=sum+ x[i][j];
	}
	avg=sum/i;
	cout<< "max: " <<max <<endl;
	cout<< "min: "<< min<< endl;
	cout <<"avg: "<<avg<<endl;
	return avg;

[Ganon11]

You call your functions like this:

statisticsR(x[i][j]);

which passes the function x[i][]j which is an integer value. But your functions are expecting a 2d array, not an integer. Try

statisticsR(x);

What Ganon11 said, plus it's good style to use capital letters for your symbolic constants (MAX1, not max1) so that they don't look like variable names.

thanks a lot. It fixed the errors in my program
