I want to know why this program is executing output like this " -111 111 0" briefly .

#include <stdio.h>
#include <string.h>
int main() {
  char string1[20];
  char string2[20];

  strcpy(string1, "Hello");
  strcpy(string2, "Hellooo");
  printf("Return Value is : %d\n", strcmp( string1, string2));

  strcpy(string1, "Hellooooo");
  strcpy(string2, "Hello");
  printf("Return Value is : %d\n", strcmp( string1, string2));

  strcpy(string1, "Hellooo");
  strcpy(string2, "Hellooo");
  printf("Return Value is : %d\n", strcmp( string1, string2));

  return 0;
}

strcmp() returned values are as follows:

if Return value if < 0 then it indicates str1 is less than str2

if Return value if > 0 then it indicates str2 is less than str1

if Return value if = 0 then it indicates str1 is equal to str2
