C++ Switch Case - An Overview

C++ Switch Case - An Overview

Introduction:
In C++, the "switch case" statement is a powerful control structure that allows programmers to execute different blocks of code based on the value of an expression or variable. It provides a concise and efficient way to handle multiple conditional branches, enhancing code readability and maintainability.

Syntax:
The basic syntax of the C++ switch case statement is as follows:

cpp
switch (expression) {
    case value1:
        // Code block for case value1
        break;
    case value2:
        // Code block for case value2
        break;
    // Additional case statements as needed
    default:
        // Code block for handling default case (optional)
        break;
}

Explanation:

• The expression is evaluated once, and its value is compared to each case constant.
• If a match is found between the expression value and a case constant, the corresponding code block is executed until the break statement is encountered.
• If there is no match, and a default case is provided, the code inside the default block will be executed. The default case is optional.

Example:

cpp
#include <iostream>

int main() {
    int day = 3;

    switch (day) {
        case 1:
            std::cout << "Monday" << std::endl;
            break;
        case 2:
            std::cout << "Tuesday" << std::endl;
            break;
        case 3:
            std::cout << "Wednesday" << std::endl;
            break;
        case 4:
            std::cout << "Thursday" << std::endl;
            break;
        case 5:
            std::cout << "Friday" << std::endl;
            break;
        default:
            std::cout << "Weekend" << std::endl;
            break;
    }

    return 0;
