C++ 程序：带break语句的switch-case

原文：https://www.studytonight.com/cpp-programs/cpp-switch-case-with-break-statement-program

大家好！

在本教程中，我们将学习如何用 C++ 编程语言用 break 语句演示 Switch Case 的概念。

C++ switch-case:

在编程中，switch-case只是多个 if-else 块的一种替代方案。它仅在满足特定条件时用于执行代码块。break 语句用于阻止代码流进入剩余的块，从而使其在满足单个条件时直接移出开关块。

为了更好地理解，我们强烈建议您访问我们在这里的一个帖子:https://www.studytonight.com/c/programs/basic/switch-case，我们在那里详细讨论了这个概念。

#include <iostream>
#include <vector>
using namespace std;

int main()
{
    cout << "\n\nWelcome to Studytonight :-)\n\n\n";
    cout << " =====  Program to demonstrate the concept of Switch Case with break statement, in CPP  ===== \n\n";

    //variable to store the operation to be performed
    char operation;

    //variable to store the operands
    int n1, n2, result;

    cout << "\nEnter the operation you want to perform: either + or - or * or / or %: ";
    cin >> operation;

    cout << "\n\n\nEnter the two operands you want to perform the operation on: \n";
    cin >> n1 >> n2;

    //Logic of Switch case with break statement
    switch (operation)
    {
    case '+':
        result = n1 + n2;
        break;
    case '-':
        result = n1 - n2;
        break;
    case '*':
        result = n1 * n2;
        break;
    case '/':
        result = n1 / n2;
        break;
    case '%':
        result = n1 % n2;
        break;

    default:
        cout << "\n\nPlease Enter a Valid Operation from the mentioned list";
        break;
    }

    cout << "\n\nResult obtained from the given data is: " << n1 << operation << n2 << " = " << result << "\n\n\n ";
    return 0;
}
