freeze with apples and cout

[LB]

can som one plz help. my program crashes when it shows how many are left.

#include <iostream>
#include <limits>
using namespace std;

int main()
{
int apples;
cout << "how many apples :";
cin >> apples;
int take;
cout << "take apples";
cin >> take;
int Left = apples-take;
if(Left < 0)
{
cout << "not enough aples" << endl;
}
else if(take = apples)
{
cout << "no apples left" << endl;
}
else
{
cout << "nunber of apples: " << left;
}
cin.ignore(numeric_limits<streamsize>::max(), '\n');
}

sorry i dont know how to keep the spaces in front

What kind of apples are you using?

[chrisname]

I see the problem. "int apples" is apples, but "int take" is oranges, and you can't compare apples and oranges so the program fails on else if(take = apples).

[BHX]

Wrong, it is failing because he didn't use code tags! :P

[Catfish3]

cin.ignore(numeric_limits<streamsize>::max(), '\n');

You should use std::system("PAUSE");.

We deprecated that version of C++.

I'm taking this as a joke.

I'm seriously dying laughing right now.

Yes, this was a satirization of those threads that just make you feel like society is turning into mush. The original point of the code was to demonstrate why "using namespace std;" is bad and why your compiler won't help you fix problems with using the wrong name, but I decided to go for the satire.

What's with the random iostream include? Does your ASCII art really need to use the bathroom that much?

[Oria]

Does your ASCII art really need to use the bathroom that much?

That made me laugh a little too much... I had a couple co-workers look at me oddly.

I did have std::cout originally in there and std::cin.ignore as well, but I took those out to reduce clutter and I guess I overlooked the #include .

[Duthomhas]

I was enjoying this up until post 9. Now I'm confused. (I see no namespace error in the code. Am I just missing something really obvious?)

Hmm, std::left?

[Oria]

I tryed this:

#include <iostream>

using namespace std;

int main()
{
    int left = 5;
    cout << left << endl;
    return 0;
}

And it compile and printed 5 as expected. std::left is part of <ios>, so maybe you would need to include that to have failure?

Edit:
I was wrong, it wont fail. Heh, possibly that you declare 'left' as a variable, you can use it as a variable. I'm too lazy to try creating a conflict between std::left and the variable int left right now though.

[chrisname]

The compiler always uses the one in the innermost scope:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

#include <iostream> int left = 0; int main() { int left = 2; { int left = 4; { int left = 6; std::cout << left; } std::cout << left; } std::cout << left << ::left; return 0; }

6420

The only way they could conflict is if they were in the same scope, so if I put using namespace std; my global int left would conflict with std::left.

[LB]

@Oria have you forgotten the fact that C++ is case-sensitive? Check my first post again to see how the variable is initially declared.

[Duthomhas]

Yes, compiler will use inner scope bindings when you rebind an identifier name. Compiler that fails == bad compiler.

But also, OP uses "Left", which is not in std::

@Oria
All the standard streams headers automatically include <ios>.
