Remove numbers from string

Here given code implementation process.

//C Program
//Remove numbers from string
#include <stdio.h>

void replace(char str[],int size)
{
  
  if(size < 1) 
  {
    return;
  }

  int x = 0;

  printf("\nBefore : %s\n",str );
  
  for (int i = 1; i < size; ++i)
  {
    if( !(str[i]>='0' && str[i]<='9') )
    {
      //When get a character
      str[x]=str[i];
      x++;
    }
  }
  //Set the remain characters
  for (int i = x; i < size; ++i)
  {
    str[i]=' ';
  }
  printf("After : %s\n",str );
