How to create multidimensional array with an input variable?

[cppfighter]

I am trying to create a multi dimensional array with and input integer

This works

#include <stdio.h>

int main()
{
  
  int n[9][9]={{0}};
  printf("%d",n[8][8]);
  return 0;
}

But this doesn't work

#include <stdio.h>

int main()
{
  int m=9;
  int n[m][m]={{0}};
  printf("%d",n[m-1][m-1]);
  return 0;
}

How should I pass array size to a multidimensional array as avariable?

This should work

#include <stdio.h>

int main()
{
  const int m=9;
  int n[m][m]={{0}};
  printf("%d",n[m-1][m-1]);
  return 0;
}
