Visual C++ - Logical and: &&

Logical and works as follows: just in case it's true if both inputs are true in all other situations the result is false. In next table you can find all possibilities:
TrueFalse False
True True True
information about the table: a, b are inputs, x is result



par1 && par2
Used keywords: &&



If the first operand is false, then the second operand is not evaluated.


Visual C++ .NET

In the source code you can find the equivalent of the above table, for easier orientation at the end of each line is a comment which shows the result.
a1 = false && false; // a1 = false
a2 = false && true; // a2 = false
a3 = true && false; // a3 = false
a4 = true && true;  // a4 = true

Visual C++ .NET

Even one example in what situations we can use the operation logical and:
a && b
a && true
10 >a && a>5

Visual C++ .NET

Other pieces of example codes:
!b && true
a && b
 b2 = x && y

You can find it in the following collections: logical operators
