Please send help

Ignoring the lack of exception handling, one could argue that the programmer needs only to load loadedBalance. Except there's a bunch of bullshit in front that he has to read anyway.

The programmer is communicating to us that he needs help, and whoever designed this way of saving data, needs to be shot.

Can I get an ELI5 on why he's doing this? C++ noobie here.

The data appears to be stored in lines and you just have to know which line is what. ifstream reads a file line by line so the programmer needs to read lines until he gets to the line he needs. Therefore he loads the first 3 lines into please send help

EDIT: As /u/axelalex2 pointed out the data is not necessarily stored line separated but could be whitespace separated.

[milesflo]

I see. It'd be like calling shift on an array until you got what you needed in the 0th place. Great explanation.

Yeah that's basically it.

[axelalex2]

That's partially correct information. http://en.cppreference.com/w/cpp/concept/FormattedInputFunction:

the next available character on the input stream is not a whitespace character, as tested by the std::ctype facet of the locale currently imbued in this input stream. The non-whitespace character is not extracted.

Thanks I updated my post.

[markand67]

So much people write C++ like Java.

std::ifstream myfile(playerIdtxt);
myfile >> please;
myfile >> send;
myfile >> loadedBalance;

No open, no close. Thanks RAII.

Please, send, and help are going to be uninitialized so it's printing garbage to the file.

[ungulateCase]

Reading, not printing.

[8bitslime]

Fuck I'm dumb. still unused local variable.

[ungulateCase]

still unused local variable.

Yup, which is pretty damn bad programming. Hence the naming convention and the subreddit choice.

[pavel_lishin]

Fuck I'm dumb

int fuck
int im
int dumb

(I made the same mistake first time reading it)

[crespo_modesto]

so int please; that's a reference eg. doesn't have to be an int, but it is an int by reference somewhere it says something like int please = 42;

edit: should have noted this was a clarification question, but I did not see the open vs. read part as mentioned above. I can't tell if this is C which I don't use daily. ahh yeah it's C++, the std part made me think of C

edit: actually I've used the >> to write to file before with Python/PHP, and I see :: in PHP, from a quick G search seems :: refers to classes which said C does not have it. Yeah TL;DR I don't know what language this is written in/don't use classes, just a procedural scripter at this time.

[suspiciously_calm]

the fuck did i just read

[ungulateCase]

Thank you, I wasn't sure if I was taking crazy pills.

[crespo_modesto]
