An enumerated data type in C ++
enum
int
double
float
char
"False" in C ++ takes the form and means:
one of the two values of type bool
lack of communication with the processor peripherals
the temporary suspension of the computer
the need to perform a "warm start"
errors when entering information
"True" in C ++ takes the form and means:
1
lie
the result of the correct compilation of the program
the absence of errors when entering information
the absence of errors in the derivation of the information
The result of a logical operation in C ++ is
true - true or false - false
