Microsoft Visual C++/cli step by Step

3. 

Build the application.

4. 

Run the application several times, typing a different month each time. Verify that the applica-

tion displays the correct month name each time.

Using fall-through in a switch statement

If you omit the break statement at the end of a case branch, flow of control continues on to the next 

statement. This process is called fall-through. This can be useful to avoid duplication of code, but be 

careful not to do it accidentally.

The following example illustrates why fall-through might be useful. This example tests a lowercase 

letter to see if it is a vowel or a consonant:

char lowercaseLetter;   // Single lowercase letter, for example 'a' 

...  

switch (lowercaseLetter) 

{ 

    case 'a': 

    case 'e': 

    case 'i': 

    case 'o': 

    case 'u':  Console::Write("Vowel"); break; 

 

    default:   Console::Write("Consonant"); break; 

}

There is no break statement in the first four case labels. As a result, the flow of control passes on 

to the next executable statement to display the message Vowel. The default branch deals with all the 

other letters and displays the message Consonant.
