# true (C++)
## Syntax  
  
```  
  
      bool-identifier = true ;  
bool-expression logical-operator true ;  
```  
  
## Remarks  
 This 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). If `i` is of type `bool`, then the statement `i = true;` assigns **true** to `i`.  
  
## Example  
  
```  
// bool_true.cpp  
#include <stdio.h>  
int main()  
{  
    bool bb = true;  
    printf_s("%d\n", bb);  
    bb = false;  
    printf_s("%d\n", bb);  
}  
```  
  
```Output  
1  
0  
```
