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

void main()
{
  int i=0;
  char *str1,*str2,*str3;

  puts("Enter first string");
  gets(str1);
  puts("Enter second string");
  gets(str2);

  printf("Before concatenation the strings are\n");
  puts(str1);
  puts(str2);

  while(*str1)
  {
      str3[i++]=*str1++;
  }
  while(*str2){
      str3[i++]=*str2++;
  }

  str3[i]='\0';
  printf("After concatenation the strings are\n");
