Write a C program to compare two strings using pointers.

Program Code:

#include<stdio.h>

#include<string.h>

int compare_strings(char *,char *);

void main()

{

char s1[50],s2[50],*p1,*p2;

int res;

printf("\n enter a string s1: ");

gets(s1);

printf("\n enter a string s2: ");

gets(s2);

res=compare_strings(s1,s2);

if(res==0)

printf("\n both the strings are identical");

else

printf("\n both the strings are not identical");

}

int compare_strings(char *p1,char *p2)

{

while(*p1==*p2)

{

if(*p1=='\0'|| *p2=='\0')

break;

p1++;

p2++;

}

if(*p1=='\0'|| *p2=='\0')

return 0;

else

return -1;

}
