void main(){
     char str1[20],str2[20],ch;
     int i;
     clrscr();
     printf(\"*****Strings Copy Function*****\\n\\n\");
     printf(\"Enter string1: \");
     scanf(\"%s\",str1);
     printf(\"\\n\\nUsing Inbuilt Function\");
     strcpy(str2,str1);
     printf(\"\\nString1 : %s\\nString2 : %s\\n\",str1,str2);

     strcpy(str2,\"\");  //empty to copy again
     printf(\"\\n\\nWithout Using Inbuilt Function\");
     for(i=0;str1[i]!=\'\\0\';i++)
    str2[i] = str1[i];
     str2[i]=\'\\0\';
     printf(\"\\nString1 : %s\\nString2 : %s\\n\",str1,str2);
