Switch statement compares the value of an expression against a list of integers or character constants.The list of constants are listed using the "case" statement along with a "break" statement to end the execution. If no conditions match then the code under the default statement is executed.

   switch(expression)
     {  
       case constant1:
          Statements
          break
       case constant2:
          Statements
          break
            .
            .
      default
          Statements
     }

  #include <iostream.h>
  using namespace std;
  int main(void)
   {
    int day;
    cout << "Enter the day of the week between 1-7::";
    cin >> day;
    switch(day)
      {
         case 1:
             cout << "Monday";
             break;
         case 2:
             cout << "Tuesday";
             break;
         case 3:
             cout << "Wednesday";
             break;
         case 4:
             cout << "Thursday";
             break;
         case 5:
             cout << "Friday";
             break;
         case 6:
             cout << "Saturday";
             break;
         default:
             cout << "Sunday";
             break;
      }
    }

   Enter the day of the week between 1-7::7
   Sunday

In the above Control Structure example the "switch" statement is used to find the day of the week from the integer input got from the user.
