C++ 'and' Keyword

"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.

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.

Syntax

    operand_1 and operand_2;

Here, operand_1 and operand_2 are the operands.

Sample Input and Output

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

Output:
result = 1

Example 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";
    else
        cout << "false\n";

    if (num >= 20 and num <= 50)
        cout << "true\n";
    else
        cout << "false\n";

    if (num > 50 and num <= 100)
        cout << "true\n";
    else
        cout << "false\n";

    return 0;
}

Output

true
true
false

Example 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.";
    else
        cout << name << " , you're not selected.";

    return 0;
}

Output

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.
