==A switch statement in action==

<source lang="cpp">
#include <iostream>
using namespace std;
int main(void)
{
char grade;
cout << "Enter your grade: ";
cin >> grade;
switch (grade)
{
case "A":
cout << "Your average must be between 90 - 100"
<< endl;
break;
case "B":
cout << "Your average must be between 80 - 89"
<< endl;
break;
case "C":
cout << "Your average must be between 70 - 79"
<< endl;
break;
case "D":
cout << "Your average must be between 60 - 69"
<< endl;
break;
default:
cout << "Your average must be below 60" << endl;
}
return 0;
}

</source>

==Deliberately falls through the case==

<source lang="cpp">
#include <iostream>
using namespace std;
int main(void)
{
char choice;
cout << "Choose your car\n";
cout << "S \n";
cout << "L \n";
cout << "D \n";
cin >> choice;
cout << "Extra features purchased\n";
switch (choice)
{
case "D":
cout << "D\n";
case "L":
cout << "L\n";
break;
default:
cout << "None\n";
}
return 0;
}

</source>

==Switch: falling-through behavior==

<source lang="cpp">
#include <iostream>
using namespace std;
int main(void)
{
char grade;
cout << "Enter your grade: ";
cin >> grade;
switch (grade)
{
case "a":case "A":
cout << "Your average must be between 90 - 100"
<< endl;
break;
case "b":
case "B":
cout << "Your average must be between 80 - 89"
<< endl;
break;
case "c":
case "C":
cout << "Your average must be between 70 - 79"
<< endl;
break;
case "d":
case "D":
cout << "Your average must be between 60 - 69"
<< endl;
break;
default:
cout << "Your average must be below 60" << endl;
}
return 0;
}

</source>
