Today we are going to talk about the C++ boolean datatype that stores either a 0 or 1 to represent 0 for _false _and 1 for anything true.
This kind of flag is used extensively in programming in general and we will look at another very basic program to understand its simple usage.
#include <iostream>
int main()
{
bool my_bool = true;
std::cout << my_bool << std::endl;
return 0;
}
We see that we are creating a bool and assigning it a _true _value or _1 _value and printing it.
Let's compile and link.
g++ -o 0x04_asm64_boolean_primitive_datatype 0x04_asm64_boolean_primitive_datatype.cpp
Let's run.
./0x04_asm64_boolean_primitive_datatype
We simply see the following.
1
It successfully echoed 1 to the terminal stdout. Very simple.
Next week we will debug this very simple example.
