Lesson 10: The bool (Boolean) type

NOTE: for a fast copy, follow these steps in order:

Click anywhere in a text box below (result will be a blinking vertical line in the text box)
Hit ctrl + A on the key board (the "ctrl + A" means hit Ctrl and A at the same time)
(The result should be that all the text inside the text box lights up in blue)
Hit Ctrl + C (Nothing significantly happens that is visible) and now its copied to the clipboard and your ready to paste it anywhere

small char programs


Boolean types can hold either true or false
#include <iostream>
using namespace std;

int main()
{
 bool smart=true;
 cout << smart;
 cin.get();
 return 0;
}

#include <iostream>
using namespace std;

int main()
{
 bool smart=false;
 cout << smart;
 cin.get();
 return 0;
}


If the value is set a number that is not equal to 0 the boolean value will be set to true
#include <iostream>
using namespace std;

int main()
{
 bool smart=13;
 cout << smart;
 cin.get();
 return 0;
}


If the value is set to 0, the boolean value will be considered false.
#include <iostream>
using namespace std;

int main()
{
 bool smart=0;
 cout << smart;
 cin.get();
 return 0;
}
