A switch statement allows you to control the flow of your program similar to if and else statements, but can be easier for the user to understand.

The Switch Statement

The structure of a switch statement is the following:

switch(expression) {
    case <constant_expression>  :
    statements
    break;

    case </constant_expression><constant_expression> :

    default :
    statements
}</constant_expression>

The If Statement

An example is as follows

int x;
if ( condition ) x = 50; //If condition returns TRUE, assign 50 to X.
 

In other words, if the condition you provide returns a boolean value ( is a value that returns either TRUE or FALSE ) TRUE, then the following statements enclosed with {}’s are executed (no need if only one statement follows the if statement). Read more »
