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
