To compare the given two string using pointers Using C

# include <stdio.h>
# include <conio.h>
void main()
{
char *str1, *str2 ;
clrscr() ;
printf("Enter the first string : ") ;
scanf("%s", str1) ;
printf("\nEnter the second string : ") ;
scanf("%s", str2) ;
while(*str1 == *str2 && (*str1 != '\0' || *str2 != '\0'))
{
str1++ ;
str2++ ;
}
if(*str1 == '\0' && *str2 == '\0')
printf("\nThe given strings are equal") ;
else
printf("\nThe given strings are not equal") ;
getch() ;
}

RUN 1 :
~~~~~~~
Enter the first string : cse
Enter the second string : ece
The given strings are not equal
RUN 2 :
~~~~~~~
Enter the first string : mech
Enter the second string : mech
The given strings are equal
