Visual C++ - Logical or: ||

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



par1 || par2
Used keywords: ||



If the first operand is true, 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 = true
a3 = true  || false; // a3 = true
a4 = true  || true;  // a4 = true

Visual C++ .NET

Even one example in what situations we can use the operation logical or:
(b || c) || a
a || true
a>1 || a<100

Visual C++ .NET

Other pieces of example codes:
(10 >a || a<5)
a || true
j > 128 || false

You can find it in the following collections: logical operators
