Question

Can I use the switch statement for non-integer types?

Answer 1

Starting from C++17, you can use the switch statement with non-integer types, such as characters and enumerated types.

Here's an example code snippet to demonstrate the usage of the switch statement:

#include <iostream>

int main()
{
    int choice;
    std::cout << "Enter a number (1-3): ";
    std::cin >> choice;

    switch (choice)
    {
        case 1:
            std::cout << "You chose option 1.\n";
            break;
        case 2:
            std::cout << "You chose option 2.\n";
            break;
        case 3:
            std::cout << "You chose option 3.\n";
            break;
        default:
            std::cout << "Invalid choice.\n";
            break;
    }

    return 0;
}
 

In this example, the user is prompted to enter a number. The switch statement checks the value of choice and executes the corresponding code block based on the entered value. If an invalid choice is entered, the default case is executed.
