Switch Statements in C++

While switch statements have been with C++ since day one, the decision to make them default their control flow to a fall through state makes them hard to troubleshoot.Switch statement is a control statement that allows us to choose only one choice among the many given choices. It is a control statement used to make a selection between many alternatives.

 
   
#include < iostream>
using namespace std;
int main() {
    int a = 1;

    switch (a) {
        case 1:
            cout << n1 << "My Choice is 1";
            break;
        case 2:
            cout << n1 << "My Choice is 2";
            break;
        case 3:
            cout << n1 << "My Choice is 3";
            break;
        default:
            // Variable "a" doesn't match any case
            cout << "Invalid! The Choice is not correct";
            break;
    }
    return 0;
}
