(print
(cons 'Hello (list 'World))))

#include <stdio.h>

void main(void)
{
char *message[] = {"Hello ", "World"};
int i;
for(i = 0; i < 2; ++i)
printf("%s", message);
printf("\n");
}

#include <iostream.h>
#include <string.h>
class string
{
private:
int size;
char *ptr;
public:
string() : size(0), ptr(new char('\0')) {}
string(const string &s) : size(s.size)
{
ptr = new char;
strcpy(ptr, s.ptr);
}
~string()
{
delete [] ptr;
}
friend ostream &operator <<(ostream &, const string &);
string &operator=(const char *);
};

ostream &operator<<(ostream &stream, const string &s)
{
return(stream << s.ptr);
}
string &string::operator=(const char *chrs)
{
if (this != &chrs)
{
delete [] ptr;
size = strlen(chrs);
ptr = new char;
strcpy(ptr, chrs);
}
return(*this);
}
int main()
{
string str;
str = "Hello World";
cout << str << endl;
return(0);
}

i=(int)tmp[8];
tmp[8]=tmp[9];
tmp[9]=(char)i;
