c++ cdi+示例

"or" is an inbuilt keyword that has been around since at least C++98. It is an alternative to || (Logical OR) operator and it mostly uses with the conditions.

“ or”是一個(gè)內(nèi)置關(guān)鍵字，至少?gòu)腃 ++ 98起就存在。 它是||的替代方法 ( 邏輯OR )運(yùn)算符，它通常與條件一起使用。

The or keyword returns 1 if the result of at least one operand is 1, and it returns 0 if all operands result is 0.

如果至少一個(gè)操作數(shù)的結(jié)果為1，則or關(guān)鍵字返回1；如果所有操作數(shù)的結(jié)果為0，則or關(guān)鍵字返回0。

Syntax:

句法：

operand_1 or operand_2;

Here, operand_1 and operand_2 are the operands.

在這里，操作數(shù)_1和操作數(shù)_2是操作數(shù)。

Example:

例：

Input:a = 10;b = 20;result = (a==10 or b==30);Output:result = 1

演示使用“ or”關(guān)鍵字的C ++示例 (C++ example to demonstrate the use of "or" keyword)

// C++ example to demonstrate the use of // 'or' operator.#include <iostream> using namespace std;int main() {int num = 20;if (num >= 10 or num <= 50)cout << "true\n";elsecout << "false\n";if (num >= 20 or num <= 50)cout << "true\n";elsecout << "false\n";if (num > 50 or num <= 100)cout << "true\n";elsecout << "false\n";return 0; }

Output:

輸出：

true true true
