Stupid Nub Question

[eNc]

Umm is it possible to write a statement in C++ similar to
a get statement in Turing where you can actually get a sentence or a word from the user ? eg..

code:

var a : string := "" put "Enter your name" get a

like cause i can't get more than 1 char from the "user"

--Thanks

code:

string stuff;   cout<<"Enter stuff:"<<endl;   cin>>stuff;

or for multiple words

code:

char stuff[255];   cout<<"Enter stuff:"<<endl;   cin.getline(stuff,255);

Start out with the basic framework of a C++ program:

code:

int main() { }

Then you need the string library and the iostream library so you can deal with strings and input and output.

code:

#include <string> #include <iostream> int main() { }

Now, you'll want an equivalent for:

code:

var a : string := ""

code:

#include <string> #include <iostream> int main() {    std::string a = ""; }

And then an equivalent for:

code:

put "Enter your name"

code:

#include <string> #include <iostream> int main() {    std::string a = "";    std::cout << "Enter your name" << std::endl; }

And an equivalent for:

code:

get a

code:

#include <string> #include <iostream> int main() {    std::string a = "";    std::cout << "Enter your name" << std::endl;    std::cin >> a; }

And just for fun, in Ruby

code:

puts "Enter your name" a = gets.strip

And Python...

code:

import sys print "Enter your name" a = sys.stdin.readline().strip()

Perl...

code:

print "Enter your name\n"; chomp(my $a = <STDIN>);

O'Caml

code:

let _ =    print_endline "Enter your name";    let a = read_line () in       print_endline a;;

Don't use char arrays when you should use std::string.

code:

#include <string> #include <iostream> int main() {    std::string line = "";    std::getline(std::cin, line); }

havent used getline much (or at all), wasnt aware it took std::strings

wtd holy you kno so many languages!

Well, there are a few I didn't list there, and my knowledge of O'Caml is just starting to come together. Yet it's an incredibly nifty language. For instance:

code:

let plus1 = (+) 1;; plus1 3;; (* Same as... *) 1 + 3;;

Or a more practical example. The Printf module has a fprintf function similar to C's. But what if, for writing error messages out I don't want to always write:

code:

open Printf Printf.fprintf stderr "%s\n" error_msg;;

I can instead write:

code:

open Printf let print_err = Printf.fprintf stderr "%s\n";; print_err "Oops...";;
