程序员的进化
不知道排版有没有问题…如果把程序员分级，那么就是：
高中时期
10 PRINT "HELLO WORLD" 20 END
大学新生
program Hello(input, output) begin writeln(\'Hello World\') end.
高年级大学生
#include int main(void){printf("Hello, world!\\n");return 0;}
职业新手
#include void main(void) { char *message[] = {"Hello ","World"}; int i; for(i = 0; i < 2; ++i) printf("%s", message); printf("\\n"); }
职业老手
#include #includeusing namespace std; class string { private: int size; char *ptr; string() : size(0), ptr(new char) { ptr = 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=(constchar *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); }

黑客学徒
#!/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;
有经验的黑客
#include #define S "Hello, World\\n" main(){exit(printf(S) == strlen(S)? 0 : 1);}

大家刚开始学C的时候 都是用的这一段 一堆乱码？ 小樱 发表于 2012-1-29 17:21 static/image/common/back.gif
一堆乱码？
编程的源代码啦~~~~~~~~~~~~~~~ 天书啊..... 根本看不懂 纯乱码啊...... jianshen1015 发表于 2012-2-1 17:57 static/image/common/back.gif
纯乱码啊......
淡定，慢慢学吧，计算机语言说难是难，说容易也容易~~~~~~~~~~~~~
