WRITE A C PROGRAM TO COMPARE TWO STRINGS ARE SAME OR NOT

#include<stdio.h>
main()
{
    char str1[10],str2[10];
    printf("Enter first string : ");
    gets(str1);
    printf("Enter second String: ");
    gets(str2);
    if(xstrcmp(str1,str2))
    printf("Both strings are same");
    else
    printf("Both strings are different");
}
int xstrcmp(char *s1,char *s2)
{
    int flag;
    flag = 1;
    while(*s1 !='\0')
    {
        if(*s1==*s2)
        {
            s1++;
            s2++;
            continue;
        }
        else
        {
            flag=0;
            break;
        }
    }
    return flag;
}
OUTPUT
Enter first string : raj
Enter second string : indra
Both strings are different
