# false (C++)
The keyword is one of the two values for a variable of type [bool](../cpp/bool-cpp.md) or a conditional expression (a conditional expression is now a **true** Boolean expression). For example, if `i` is a variable of type `bool`, the `i = false;` statement assigns **false** to `i`.  
  
## Example  
  
```  
// bool_false.cpp  
#include <stdio.h>  
  
int main()  
{  
    bool bb = true;  
    printf_s("%d\n", bb);  
    bb = false;  
    printf_s("%d\n", bb);  
}  
```  
  
```Output  
1  
0  
```
