一般來說,
一個軟體工程師將按如下幾個階段成長下去:
*****高中時代*****
10 PRINT "HELLO WORLD"
20 END
*****大學新生*****
program Hello(input, output)
begin
writeln('Hello World')
end.
*****高年級學生*****
(defun hello
(print
(cons 'Hello (list 'World))))
*****新來的程式設計師*****
#include
void main(void)
{
char *message[] = {"Hello ", "World"};
int i;
for(i = 0; i < 2; ++i)
printf("%s", message);
printf("\n");
}
*****經驗豐富的程式設計師*****
#include
#include
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[size + 1];
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[size + 1];
strcpy(ptr, chrs);
}
return(*this);
}
int main()
{
string str;
str = "Hello World";
cout << str << endl;
return(0);
}
*****學徒等級的HACKER*****
#!/usr/local/bin/perl
$msg="Hello, world.\n";
if ($#ARGV >= 0) {
while(defined($arg=shift(@ARGV))) {
$outfilename = $arg;
open(FILE, ">" . $outfilename) || die "Can't write $arg: $!\n";
print (FILE $msg);
close(FILE) || die "Can't close $arg: $!\n";
}
}
else
{
print ($msg);
}
1;
*****中級HACKER*****
#include
#define S "Hello, World\n"
main()
{exit(printf(S) == strlen(S) ? 0 : 1);}
*****老練的HACKER*****
% cc -o a.out ~/src/misc/hw/hw.c
% a.out
*****魔法HACKER*****
% cat
Hello, world.
^D
*****專案組長*****
10 PRINT "HELLO WORLD"
20 END
*****部門經理*****
mail -s "Hello, world." bob@b12
Bob, could you please write me a program that prints "Hello, world."?
I need it by tomorrow.
^D
*****總經理*****
% zmail jim
I need a "Hello, world." program by this afternoon.
