10 PRINT “HELLO WORLD”
20 END

 




First year in College
program Hello(input, output)

begin
writeln(‘Hello World’)

end.




Senior year in College
(defun hello

(print

(cons ‘Hello (list ‘World))))




New professional
#include <stdio.h>
void main(void)

{

char *message[] = {“Hello “, “World”};
int i;

for(i = 0; i < 2; ++i)
printf(“%s”, message[i]);

printf(“\n”);

}




Seasoned professional
#include <iostream.h>

#include < string.h>

class string
{

private:

int size;

char *ptr;

public:
string() : size(0), ptr(new char(”)) {}

strcpy(ptr, s.ptr);

}
