Me and my 2.8+ million lines of code

I wrote a 2700 line program to generate 2.8 million lines of if/and statements, which it now happily spams into my command prompt, via cout<<. The problem is that my command prompt apparently doesn't remember all 2.8 million lines (I think the buffer max is like 999 lines), is there a way I can output my newly generated code somewhere that I can read it, and then cut and paste it into my compiler -- Notepad perhaps?

write it out to a a file

I'm no expert but...

won't that take an awful long time to compile?

Salem really sums it up...

>>> Sounds like you need a better approach

... what on Earth are you trying to do?

2.8 million lines? Why? What are you trying to do?

Hm, 2.8 million if's? Ouch. Wouldn't it be better to find some way to use a loop or something? Or maybe a better test condition or something?

Also, I don't think Notepad can handle 2.8-million line files. It choked on a 2Kb file or something for me, and 2.8 million lines is going to be something like 28Mb...

You're a freak.

Hunter2:

2KB choked it??????

If you right-click on a file you will see view(lister).

That works in notepad. Bigger files will be put in wordpad.

I did it with a 600 MB file.. so HA! you need a new hardrive.... try the Alien 4

if you are under linux console try this ./executablename >dumpfile and you will have all the output send to dumpfile

You can do that under Windows as well, as Salem suggested.

>it choked on 2kb??
Oops, memory lapse. It choked on 100k actually, but the end result is still the same, notepad won't handle a 28Mb file. And yes, I know that Wordpad will handle large file sizes; no need to boast about your harddrive handling a 600mb textfile or whatever it was, I've had wordpad handle a 30.2Gb textfile. So... :) I'll just keep my cheap no-name brand econosaver harddrive that I got for a few pennies ;)

I don't know what you're doing, but have you at least considered a Switch...case statement, if you can't think of any other ways to do it? Because 2.8 million lines of nothing but if statements is ridiculous.

lol yah uh, gimme a url to a good tutorial on switch ive never used it before

Try this. Things aren't always that hard to find; and cprogramming.com has a lot of good tutorials for the basics.

Code:

---

cin>>input;       

  switch (input)       

  {         

  case 1: playgame();

          break;

---

if input is:

char input[256]

and case 1=playgame

then how would the above be rewritten?

You can't.
char[256] is a pointer to a char, and if you did a switch, you would be checking the address of a char (the 1st element of an array of chars). So input would be interpreted as something like 23847981 (the address of the first char), instead of whatever the user typed in. You could do:

Code:

---

switch(*input)
{
}

---

But that would only check the first letter of input, so you still have to use strcmp(input, "asdf") to check the input of a string.

i guess im asking for how exactly strcmp would look in that. All I can do with strcmp is

Code:

---

if (!strcmpi("n", command) || !strcmpi("no", command))

---

and i have no idea how it would fit into a switch statement

Hmm, not sure what you're asking, but it would be easier to just check if the first letter is 'n', since that's pretty similar to what you're doing:

Code:

---

if(command[0] == 'n')

---

easy money....

Switch case statement are like if statements, except easier to handle multiple stats with one char, int, flaot, etc.

like:

Code:

---


int choice;
cin >> choice;
switch (choice)
{
  case '1' : cout << "you choose 1\n";
  break;
  case '2' : cout << "You choose 2\n";
  break;
  defualt : cout << "please press a real button\n";
  break;
}

---

opposed to:

Code:

---

if (choice == '1')
{
 cout << "You choose 1\n";
}

else if (choice == '2')
{
 cout << "You choose 2\n");
}

else
{
  cout << "please press a real key\n";
}

---

See? Hope that helps.

Sorry, didn't see the previous coding here... :eek:

By the way:

Code:

---

int choice;
cin >> choice;
switch (choice)
{
  case 1 : cout << "you choose 1\n";
  break;
  case 2 : cout << "You choose 2\n";
  break;
  defualt : cout << "please press a real button\n";
  break;
}

---

The quotes would screw up the result, 'cuz then it would check for the ascii values of '1', '2', while the input stored in choice is in integer form.

if i dont have the ' ' around it it get errors.

Then something must be screwy with your compiler... putting ' ' around the letter only changes the letter into an ascii value, which is an int anyways. Besides, what error are you getting?

But what If im not entering an integer? Then

case 1 doesnt mean anything

Code:

---


char input;
cin >> input;

switch(input)
{
      case 'n':
                  cout << "You pressed n";
                  break;
      case 'p':
                cout << "You pressed p";
                break;
      default:
                cout << "You didn't press n or p";
}

---

switch statements can only deal with ints or chars, no arrays or floats.

oh - someone should write a tutorial that explains that, thanks

You should buy a reference book, they're invaluable resources.

Get Primer C++, its one of the BEST out there.
