Q:

How to write the content of an array into a text file?

How to write the content of an array to a text file?
Is it possible?
Below is my code:
x=0;
y=0;
//copy to real array
if(nRow == 0){
    for(i=nTCol; i>=0 ; i--){
        nPanelMap[nRow][x] = nTempMap[i];
        x++;
    }

}
if(nRow == 1){
    for (i=nTCol; i>=0 ; i--){
        nPanelMap[nRow][y] = nTempMap[i];
        y++;
    }
}
k=0;

for (i=nTCol; i>=0 ; i--){
    array [k] = nPanelMap[nRow][x];
    k++;
    array [k] = nPanelMap[nRow][y];
    k++;

}
j=0;
for (i=nTCol; i>=0 ; i--){

    nPanelMap[nRow][j] = array [k];
    j++;
}
nRow++;

I would like to print out arrays x, y, k, and j and write them into a text file.
The purpose of doing this is to ensure that the data passing is correct.

A:

Yes, you can write into a text file. 
#include <iostream>
#include <fstream>
using namespace std;

int main () {
  const int size = 5;
  double x[] = {1,2,3,4,5}; 

  ofstream myfile ("example.txt");
  if (myfile.is_open())
  {
    myfile << "This is a line.\n";
    myfile << "This is another line.\n";
    for(int count = 0; count < size; count ++){
        myfile << x[count] << " " ;
    }
    myfile.close();
  }
  else cout << "Unable to open file";
  return 0;
}

To write array data use this.
for(int count = 0; count < size; count ++){
            out_myfile << x[count] << " " ;
}
