A Boolean data type is a data type that can be either one of these two values: true or false. It was originally added to the C++ language by the ISO/ANSI(International Standards Organization/American National Standards Organization) committee in 1998. The expressions are named after the English mathematician George Boole, who formulated rules for mathematical logic. Boolean expressions also end up with a value of either true or false. Boolean expressions are used in branching and looping statements. In programming, a boolean can be used with conditional statements (statements that only happen when the right condition is met).
Examples
An example of a boolean in pseudocode:
if (Boolean_Expression)
{
Yes_Statement_1
...
Yes_Statement_Last
}
else
{
No_Statement_1
...
No_Statement_Last
}
Boolean data types can also be used with other booleans inside of conditional statements using a conjunction operator. For example:
if (Boolean_Expression1 and Boolean_Expression2)
{
Yes_Statement_First
...
Yes_Statement_Last
}
else
{
No_Statement_First
...
No_Statement_Last
}
It can also be used with a disjunction operator:
if (Boolean_Expression1 or Boolean_Expression2)
{
Yes_Statement_First
...
Yes_Statement_Last
}
