Compiler Warning (level 1) C4804
'operation' : unsafe use of type 'bool' in operation
This warning is for when you used a bool
variable or value in an unexpected way. For example, C4804 is generated if you use operators such as the negative unary operator (-) or the complement operator (~
). The compiler evaluates the expression.
Example
The following sample generates C4804:
// C4804.cpp
// compile with: /W1
int main()
{
bool i = true;
if (-i) // C4804, remove the '-' to resolve
{
i = false;
}
}
