Reason for getting garbage value in C

I'm running this code and getting some garbage value while printing *ptr. What could be the possible reason and how can I avoid getting that?

# include <stdio.h>
int main()
{
  int test = 1; 
  int *ptr = &test;
  *ptr++ = 10; 
  test++; 
  printf("\nThe value is %d", *ptr);
}

The statement *ptr++ increments the pointer which could not be valid for your program. Rewrite the statement as *ptr = 10;

You moved ptr with ptr++. Why?

Don't do that.
