C++ If statment question

hi guys, i am currently learning c++ and am curious. Are you able to use an if statement with in an if statement as long as you have { ....} separating it from int main??? Sorry if that is not written correctly, im still new. Thanks

Code:

---

if ( guess < 74 ) {
                cout << "Sorry, you guessed wrong!\n";
                cout << "Would you like a hint?\n" << "\n" << "\n" << "<y/n>";
                cin >> clue;
                        if ( clue == y )


        }

---

Code is incomplete, but it should give u an idea.

Roughly, yes, though you can do:

Code:

---

if (x)
    if (y)
        if (z)
            foo();

---

but that can be prone to incorrect maintenance when someone inserts a statement and forgets to add the braces.

Hehe, although in laser's example, you could just do:

Code:

---

if (x && y && z)
    foo();

---

It's less error prone.
But you can have as many (?) nested if statements as you wish. Everything at the first line
following the if (see example above) or within the braces (

Code:

---

{ and }

---

) are considered part of the if statement.
You can, of course, also have several if statements after each other in a function.

im sorry to bother, but could you further clarify what you mean? For instance, what is foo();

Code:

---

#include <iostream>       

using namespace std;
               
int main() {
 
       
        int guess;                   
        int clue;
       
       
        cout << "Hello Internet\n";
        cout << "Today, we are going to play the guessing game!\n";
        cout << "\n";
        cout << "You are going to pick a number from 1-100 and if you need help\n" << "Id be happy to give you clues!\n" << "\n";
       
        cout << "Pick a number: ";
        cin >> guess;
        cout << "\n";
        cin.ignore();                     
 
                if ( guess < 74 ) {
                cout << "Sorry, you guessed wrong!\n";
                cout << "Would you like a hint?\n" << "\n" << "\n" << "<y/n>";
                cin >> clue;
                        if ( clue == y )
                       
                  // Add in couts etc...

        }

        else if ( guess > 74 ) {           
        cout << "high\n";
            }

        else {
        cout << "You won the game!\n";   
        }

  cin.get();
 
  return 0;
}

here is my full code that i have right now to better clarify. im new to c++ and all coding, as in i started doing research yesterday and am loving it. I cant really explain the feeling when writing something and having it work lol. thanks

This is valid code, but I think you had better take a better look at indenting:
http://cpwiki.sourceforge.net/Indentation
http://cpwiki.sourceforge.net/User:Elysia/Indentation
And also, characters must be surrounded with '' (ie, 'y').
If you simply type y, the compiler will think it's a variable, and there's no such thing, is there?

lol, when i copy pasted, it realigns things lol. sorry

Code:

---

if ( clue == 'y' )

---

do u mean like that? I apologize again

Yes, that's right.
But I did notice you were mixing spaces and tabs. This usually creates messed up indentation when copying and pasting.
I do suggest you avoid it. Pick one.

Is this code incorrect? When i run it, if i choose y, it just says press enter to continue with out displaying the cout. Whats wrong?

Code:

---

        if ( guess < 74 ) {
        cout << "Sorry, you guessed wrong!\n";
        cout << "Would you like a hint?\n" << "\n" << "\n" << "<y/n>";
        cin >> clue;
                if ( clue =='y' ) {
                cout << "You guessed low, sorry! Try again!\n";
                }

        }

---

Code:

---

        if ( guess < 74 ) {
                cout << "Sorry, you guessed wrong!\n";
                cout << "Would you like a hint?\n" << "\n" << "\n" << "<y/n>";
                char clue;
                cin >> clue;
                if ( clue =='y' ) {
                        cout << "You guessed low, sorry! Try again!\n";
                }
        }

Try adding something such as that.
It doesn't like to read a char into an int, apparently.

That worked, thank you very much. So i have to ask what exactly it did if you don't mind.

It read the data into the local variable clue (which is char, not int).
The char clue variable hides the int clue variable in the outer scope.

ok, i get it. thanks

Use emacs. Pressing 'Tab' indents your code (if not already indented automatically), if there is a syntax error you'll see it automatically in the indentation.
There is a command 'Untabify' to convert tabs in spaces, there is a lot of flexibility in indentation etc etc etc.
Much, so much better than the Visual Studio editor or Notepad++ ....

EDIT: a link : http://www.gnu.org/software/emacs/

You can customize emacs entirely, the standard installation already supports many languages (more than visual studio's editor): html, xml, C/C++, fortran, python, java, LaTeX, bibtex

I doubt it. That's your individual opinion.
VS allows for auto indentation, can indent code you copy into it, as well.
No need for indentation "error" notification, if you just let it indent by itself.

Again, this is individual preference.

MarkZWEERS is an infidel! He has sinned against the One True Editor. May GVim have mercy on his soul.
