How to type the symbol representing or in c++

The symbol for "or" in C is the double vertical bar (||). The logical OR operator is used to combine two Boolean values: if at least one operand is true, the result is true; otherwise, the result is false. It is left associative and has lower precedence than the logical AND operator.

The symbol that represents "OR" in C

The symbol that represents the logical "OR" operation in C language is Double vertical bar (||).

Logical OR operation

The logical OR operation (also called logical disjunction) is a Boolean operation that operates on two Boolean values , and returns a Boolean value. The result of the OR operation is true if at least one operand is true; otherwise, the result is false.

Use of "||" symbol

In C, you can use the double vertical bar (||) operator to combine two Boolean expressions:

<code class="cpp">bool result = condition1 || condition2;</code>

If condition1 or condition2 is true, then result is true; otherwise, result is false.

Examples

Here are some examples of using the "||" operator:

<code class="cpp">// 如果 x 大于 0 或 y 等于 10，则为真
bool isTrue = (x > 0) || (y == 10);

// 如果字符串不是空或不等于 "none"，则为真
bool isValid = (!str.empty()) || (str != "none");</code>

Note

• The "||" operator is left-associative, which means it evaluates from left to right.
• The "||" operator has lower precedence than the "&&" (logical "AND") operator.
