The following code compares the strings alphabetically:

For example:

1. "bite" is greater than "apple" even though length of bite
is less than apple. ( it is greater lexicographically)

2. "It is good" is lower than "It is great".

CODE -->

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

void strings_compare(char [], char []);

void main()
{
char str1[50], str2[50];
clrscr();
flushall();
printf("String 1 : ");
gets(str1);
flushall();
printf("String 2 : ");
gets(str2);
strings_compare(str1,str2);
getch();
}

void strings_compare(char str1[], char str2[])
{
int i=0,j=0,flag1=0,flag2=0;
printf("\nString 1 : ");
puts(str1);
printf("\nString 2 : ");
puts(str2);
printf("\n");
while(str1[i] != '\0' || str2[j] != '\0')
{
if(str1[i] < str2[j])
{
flag1 = 1;
break;
}
if(str1[i] > str2[j])
{
flag2 = 1;
break;
}
else
{
i++;
j++;
}
}

if(flag1==1)
{
printf("\n\ns1 : %s is lower than s2 : %s",str1,str2);
}
else if(flag2 == 1)
{
printf("\n\ns1 : %s is greater than s2 : %s",str1,str2);
}
else
{
printf("\n\nBoth strings are equal...");
}
}
