getline help

[jp01cf01]

Ok, so the way I understand it, getline is used to get user input that may contain spaces, but I'm not entirely sure of how it works. I tried looking it up on this website, but in my code, it kinda skips past it and goes back to it.
like:

string word;
getline (cin, word);
cout << "display text\n";

that displays the output, and then asks for input. I know I'm doing something wrong, but I dont know what...

[jp01cf01]

I dunno if i'm being annoying by doing this so soon, but bump .-.

After the getline(cin, word);, the first line you input at console gets loaded into the string word. Then you can output word using cout.

[jp01cf01]

But, shouldnt it try to do that before it goes on to other parts of the code?

[Code Assassin]

Alright. Try This:

#include <iostream>
#include <string>
using namespace std;
int main (void)
{

string word;
getline (cin, word);
cout << word;
return 0;

}

If the problem still continues, please show all of your syntax(if any).

[jp01cf01]

string action;
do
{
getline(cin, action);
cout << action;
if (action == "Attack")
{
break;
}
else if (action != "Run Away")
{
cout << "Nope. Try Again.\n";
cin >> action;
}
}while (action != "Attack" && action != "Run Away");

This displays "Nope. Try Again." and then asks me for input, when i type "Run Away", it only displays " Away" and continues to say "Nope. Try Again"

[jp01cf01]

Anybody? DX

[aruawons]

Your logic seems messed up. Assuming the only acceptable commands are "Attack" and "Run Away", here's the code:

string action;
do
{
  getline(cin, action);

  if (action == "Attack" || action == "Run Away")
    cout << action << endl;

  else
    cout << "Nope. Try Again." << endl;
} while (action != "Attack" && action != "Run Away");

[jp01cf01]

Thanks for that, you got my Run Away command up and running :P I dont know what I was thinking when I typed that up xD I still have it displaying "Nope. Try Again." the first time it goes through the loop though O_o

[aruawons]

The "Nope" sentence won't be displayed unless your input action is illegal (i.e. neither "Attack" nor "Run Away"), since the "if else" statement is mutually exclusive.

[jp01cf01]

But I dont input anything, much less anything illegal, yet it still displays it. Do you want to see the entire function?

[aruawons]

If you don't input anything, a NULL character is loaded into action, which is ILLEGAL. =)

[jp01cf01]

then how do I keep it from doing that DX

[aruawons]

Any reason you don't want to input a command? If there is such a circumstance, you might need a "if else" statement before the loop.

[jp01cf01]

Wait, what? No, I'm saying that before it even asks me for input, it displays the "Nope" sentence

[aruawons]

Post that particular segment of codes here so that I can take a look. Shouldn't be a big problem.

[jp01cf01]

cout << "What will you do?\n";
cout << "\nAttack\nRun Away\n\n";
string action;
do
{
getline(cin, action);
if (action == "Attack" || action == "Run Away")
{
break;
}
else
{
cout << "Nope. Try Again." << endl;
}
} while (action != "Attack" && action != "Run Away");

[aruawons]

Works totally fine to me. I think you have some misunderstanding of the semantics, but I don't know which part.

[aruawons]

Maybe you tend to hit the Enter button every time before inputting a string?.. XD

[jp01cf01]

No, I don't think thats it... maybe it has something to do with something else that surrounds it... is there anything wrong with this?:

while (pEnemy->m_eCHp > 0 && pHero->m_hCHp > 0)
{
cout << "What will you do?\n";
cout << "\nAttack\nRun Away\n\n";
string action;
do
{
getline(cin, action);
if (action == "Attack" || action == "Run Away")
{
break;
}
else
{
cout << "Nope. Try Again." << endl;
}
} while (action != "Attack" && action != "Run Away");

if (action == "Run Away")
{
cout << "You ran away.\n";
break;
}

if (pHero->m_hSpd >= pEnemy->m_eSpd)
{
int damage = pHero->performAttack(pEnemy);
pEnemy->m_eCHp = pEnemy->m_eCHp - damage;
pHero->Name();
cout << " dealt " << damage;
cout << " damage to ";
pEnemy->Name();
cout << endl;

if (pEnemy->m_eCHp <= 0)
{
break;
}

damage = pEnemy->performAttack(pHero);
pHero->m_hCHp = pHero->m_hCHp - damage;
pEnemy->Name();
cout << " dealt " << damage;
cout << " damage to ";
pHero->Name();
cout << endl;

if (pHero->m_hCHp <=0)
{
break;
}

cout << "\nYour Hp: " << pHero->m_hCHp;
cout << "\nEnemy Hp: " << pEnemy->m_eCHp << endl;
}
else if (pHero->m_hSpd < pEnemy->m_eSpd)
{
int damage = pEnemy->performAttack(pHero);
pHero->m_hCHp = pHero->m_hCHp - damage;
pEnemy->Name();
cout << " dealt " << damage;
cout << " damage to ";
pHero->Name();
cout << endl;

if (pHero->m_hCHp <=0)
{
break;
}

damage = pHero->performAttack(pEnemy);
pEnemy->m_eCHp = pEnemy->m_eCHp - damage;
pHero->Name();
cout << " dealt " << damage;
cout << " damage to ";
pEnemy->Name();
cout << endl;

if (pEnemy->m_eCHp <= 0)
{
break;
}

cout << "\nYour Hp: " << pHero->m_hCHp;
cout << "\nEnemy Hp: " << pEnemy->m_eCHp << endl;
}
}
