C Program Code For Comparing two Strings On The Basis of Their ASCII value Without strcmp function, custom made STRCMP function

/* The Following C Program code defines a self made srtcmp function which compares between 2 strings. The user is asked 2 strings, the program compares them & displays the result on the basis of ASCII weightage */

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>

int newstrcmp(char *s1, char *s2)
{
int r=0;
while(*s1!='\0'||*s2!='\0')
{
 if(*s1!=*s2)
 {
 r=(int)(*s1-*s2);
 return r;
 }
 s1++;
 s2++;
}
return r;
}

int main()
{
  char s1[100], s2[100];
  int d;
  printf("\nEnter the First String:");
  gets(s1);
  printf("\nEnter the Second String:");
  gets(s2);
  d=newstrcmp(s1,s2);
  if(d<0)
  printf("\nSecond String %s have Bigger ASCII Weightage",s2);
  else if(d>0)
      printf("\nFirst String %s have Bigger ASCII Weightage",s1);
  else
      printf("\nBoth Are Equal String!");
  getch();
  return 0;
}
