Cursor positioning by using arrow keys for getch in C

Question

I am very beginner in C and would like to code something which gets name from user and rearrange it with backspace, cursor(by using arrow keys).

In the program, when user writes his name and press ESC it has to stop the program and print the name on the screen.

So far, I was able to do ESC and Backspace parts with usign getch() and their ASCII codes, but I'm having problem on moving cursor by using arrow keys when user tries to rewrite or rearrange his name.

Here is my code:

#include<stdio.h>
#include<conio.h>

int main() {
  int i, k = 0;
  char character;
  char samplearray[100];

  printf("Enter your name:
");

  while (1) {
    character=getch();

    if (character != 0x1B && character != 0x8 && character != 0x4B) {
      samplearray[k] = character;
      k++;
      printf("%c", character);
    }

    else if (character == 0x8) {        //Deleting procces in name and it works without any problem.
      samplearray[k];
      k--;
      system("cls");
      printf("Enter your name:
");
      for (i = 0; i <= k; i++) {
        printf("%c", samplearray[i - 1]);
      }
    }

    else if (character == 0x4B) {        //Having a problem on this part.
      samplearray[k] = character;
      k--;
      printf("", samplearray[k]);
    }

  else
    break;
  }
  printf("
Your name is: 
");
  for (i = 0; i <= k - 1; i++) {
    printf("%c", samplearray[i]);
  }
  getch();
  return 0;
}
