Replace return using tab for standard input

Question

I wrote a C ++ program to input values ​​for an NxN matrix. Typically, you can enter an integer and press the Return key for NxN times. But I would like the cursor to move the tab length for each value entered by the user. This is done for the line, and then a new line is displayed for input for the next line. I know the use of curses.h for such an implementation, but have not figured out how to implement it.

Thank.

#include <ncurses.h>
#include <iostream>

using namespace std;

int main()
{
  char ch[10];
  int array[4][4];
  initscr();
  raw();
  keypad(stdscr, TRUE);
  echo();

  printw("Enter elements a 4x4 array: \n");
  for(int i=0;i<4;i++) {
    for(int j=0 ; j<4; j++) {
      getstr(ch);
      array[i][j]=atoi(ch);
      addch('\t'); // This is executed after the newline return is received
      refresh();
    }
    addch('\n');
  }

  getch();
  endwin();
  return 0;
}

The question is missing code: what have you tried? What is the problem?

If the user has decided to press enter after each element, after each element must be entered. If he simply divides the objects into a space, he should not display anything else.
