puts(s);
printf("string 2 is ");
puts(s1);
}
Output:
Example Program:
C program to compare two strings without using string handling functions.
#include<stdio.h>
#include<string.h>
main()
{
char a[10],b[10];
int i;
printf("enter string1 ");
gets(a);
printf("enter string2 ");
gets(b);
printf("given string are\n ");
puts(a);
puts(b);
for(i=0;b[i]!='\0';i++)
{
a[i]=b[i];
}
a[i]='\0';
printf("after copy\n ");
