C++ Introduction
Simple Operators
The assignment operator (=
):
main.cpp
It works exactly the same with the string
data type:
main.cpp
The equality (==
) and inequality (!=
) operators are used to numerically compare 2 variables:
main.cpp
Why 1 and 0? This is an alternative approach for utilizing the boolean data type. When the expression var == 9
is true
, it is represented as 1, and it means that var
is indeed equal to the number 9. Conversely, when the expression var == -9
is false
, it is represented as 0, indicating that var
is not equal to the number -9.
The inequality (!=
) operator is doing exactly the opposite:
main.cpp
Everything was clear?
