c++ cdi+示例

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

“ and”是一個內置關鍵字，至少從C ++ 98起就存在。 它是&& ( 邏輯AND )運算符的替代方法，它通常與條件一起使用。

The and keyword returns 1 if the result of all operands is 1, and it returns 0 if the result of any condition is 0.

如果所有操作數的結果均為1，則and關鍵字將返回1，如果任何條件的結果為0，則它??將返回0。

Syntax:

句法：

operand_1 and operand_2;

Here, operand_1 and operand_2 are the operands.

在這里，操作數_1和操作數_2是操作數。

Example:

例：

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

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

Example 1:

范例1：

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

Output:

輸出：

true true false

Example 2:

范例2：

// Input name, age, height and weight // check you are eligible for the // army selection or not?#include <iostream> using namespace std;int main() {string name;int age;float height, weight;cout << "Enter name: ";cin >> name;cout << "Enter age: ";cin >> age;cout << "Enter height (in cm): ";cin >> height;cout << "Enter weight (in kg): ";cin >> weight;if (age >= 18 and height >= 165 and weight >= 55)cout << name << " , you're selected.";elsecout << name << " , you're not selected.";return 0; }

Output:

輸出：

RUN 1: Enter name: Shivang Enter age: 23 Enter height (in cm): 172 Enter weight (in kg): 67 Shivang , you're selected.RUN 2: Enter name: Akash Enter age: 19 Enter height (in cm): 157 Enter weight (in kg): 70 Akash , you're not selected.
