how to define range of numbers inside a if condition in c++

To define a range of numbers inside an if condition in C++, you can use the logical AND operator (&&) to check if a variable is greater than or equal to a lower bound and less than or equal to an upper bound. Here is an example:

int num = 5; // The number to check

if (num >= 1 && num <= 10) {
    // Code to be executed if num is between 1 and 10 (inclusive)
    cout << "The number is within the range of 1 to 10." << endl;
} else {
    // Code to be executed if num is not between 1 and 10
    cout << "The number is not within the range of 1 to 10." << endl;
}

In the above example, the if condition checks if num is greater than or equal to 1 (lower bound) and less than or equal to 10 (upper bound). If num satisfies both conditions, the code inside the if block will be executed. Otherwise, the code inside the else block will be executed.

Note: The code inside the if and else blocks can be replaced with any code that you want to execute based on whether the number is within the specified range or not.
