Equality of strings using recursion

Problem statement

Write a c program to check weather two given strings are equal or not using recursion

#include<stdio.h>
int compair(char str1[],char str2[]);
int main()
{
  char str1[20],str2[30];
  int y;
  printf("enter string 1 ");
  scanf("%s",str1);
  printf("enter string 2 ");
  scanf("%s",str2);
  y=compair(str1,str2);
  if(y==1)
    {
      printf("strings arte same \n");
    }
  else
    {
      printf("string are different \n");
    }
  return 0;
}
int compair(char str1[],char str2[])
{
  if(*str1!=*str2)
    {
      return 0;
    }
  if(*str2=='\0'&&*str1=='\0')
    {
      return 1;
    }
  else if(*str1==*str2)
    {
      return compair(str1+1,str2+1);
    }

}
