C++/Data Type/Bool
Define and use bool value
#include <iostream>
using namespace std;
int main()
{
bool outcome;
outcome = false;
if(outcome)
cout << "true";

}
Demonstrate bool values.
#include <iostream>
using namespace std;
int main() {
bool b;
b = false;
cout << "b is " << b << endl;
b = true;
cout << "b is " << b << endl;
if(b) // control the if statement
cout << "This is executed.\n";
b = false;
if(b)
cout << "This is not executed.\n";
// outcome of a relational operator is a true/false value
cout << "10 > 9 is " << (10 > 9) << endl;
return 0;
}
