2.6.2.A bool value can control the if statement

#include <iostream> 

using namespace std;  

 

int main() { 

  bool b; 

 

  b = false; 

  cout <<  "b is " << b << "\n"; 

 

  b = true; 

  cout <<  "b is " << b << "\n"; 

 

  

  if(b) cout <<  "This is executed.\n"; 

 

  b = false; 

  if(b) cout <<  "This is not executed.\n"; 

 

  return 0; 

}

b is 0
b is 1
This is executed.
