Getchar?

[nolannpm]

I was trying to make a simple greeting program in which the program asks for a name then outputs "Hello, *name*" but it only prints the first letter of the input name.

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
string name;
string final_greeting;

cout<< "What's your name?";
name = getstring();
cout<< "Hello, ";
cout<< name;
cout<< "\n";

system("PAUSE");
return EXIT_SUCCESS;
}

Does that even compile? getstring() isn't a function. You probably want getline, like so:

#include <iostream>
#include <string> // use the string header if you are using strings

int main(int argc, char* argv[]) {
    std::string name;

    std::cout << "What's your name? ";
    std::getline(std::cin, name);

    std::cout << "Hello, " << name << "\n";

    // better way of pausing the console
    std::cin.sync();
    std::cin.get();
    return 0;
}

No it wouldn't compile. getstring() was something i found in a really old book. I kinda figured it wouldn't work. what is the cin. ?

I think getstring() might have been a Borland macro.

What exactly are you asking? cin is an input stream wrapper, that has a few functions that I have used here to pause the console. The sync function 'synchronizes' the program's input stream with what is actually there, effectively ignoring everything in the console. Then, the get method is simply a function that 'gets' a single character, which can be used to pause the console until 'ENTER' (a single character) is pressed.

It works same as your getstring() is supposed to do in your view.It accepts inputs values from keyboard .But it eats up all the blank spaces ie you cannot enter blank spaces for use like

Jack son(blank space b/w k and s)

so use cin.getline(size of string,name of character variable,delimiter);
