whats a bool

i have a question whats a bool and what does it do i read it but it dont make snes to me

bool is TRUE or FALSE...

bool returns true or false depending on the condition

for example, since i is 0 it will return true (in otherwords 1), otherwise it would return 0 if false.

Code:

---


foo()
{

    int i=0
    if( i==o)return true;
  else return false;
 
}

Actually, compiling for windows, BOOL is either TRUE or FALSE (it's an enum), whereas bool is true or false (bool, true, false are C++ keywords).

A boolean variable (bool) has only one of 2 values, it is either true or false.

oh yeah. My bad.

bool is a variable type, and variables of type bool can have one of two values: true or false. Here is an example:

Code:

---

#include<iostream>
using namespace std;

int main()
{
        bool answer;

        answer = false;

        if(answer == true)
                cout<<"You correctly answered the question.\n";
        else
                cout<<"You're answer was incorrect.\n";

        return 0;
}

was that supposed to be some kind of Sarcasm ooooooo

nope its just that im trying to understand everything i always say oooooooo i dunno why

It's a type of variables that can store one of two possible values: a bool variable can either have the value true or false (be true or false).

It isn't that much different from a a type like int. The only thing that might be strange at first is that it doesn't store a number but... uhm...one of two possible words: true or false. But don't get this wrong, it's not a string or something like that. It's not a numeric type either, but close to it.

Code:

---

int a, b;
bool somebool;

a = 1;
b = 2;
somebool = (a==b);

if (a==b) {
        cout << "(a==b) == true" << endl;
};
if (somebool) {
        cout << "(somebool) == true" << endl;
};

---

somebool would be false because a != b. That means there will be no ouput from this example code unless you set a=b.

hmmmmmm ok i get it now thnxs everyone
