C - switch case statement in C Programming with example.

Switch statement in C When you want to solve multiple option type problems, for example: Menu like program, where one value is associated with each option and you need to choose only one at a time, then, switch statement is used. Switch statement is a control statement that allows us to choose only one choice among the many given choices.

The body of a switch statement is known as a switch block. A statement in the switch block can be labeled with one or more case or default labels. The switch statement evaluates its expression, then executes all statements that follow the matching case label. You could also display the name of the month with if-then-else statements.

However a problem with the switch statement is, when the matching value is found, it executes all statements after it until the end of switch block. To avoid this, we use break statement at the end of each case. The break statement stops the program from executing non-matching statements by terminating the execution of switch statement.

You've declared s as an integer but attempt to use it as a character and character array. You should probably declare it is char s; and then use it consistently as just a single character -- which does mean that you can't check for XL.You could, however, just check for X in your switch. If you absolutely must check for XL, then you'll need to use either a character array or std::string.

A switch statement can be nested. When nested, the case or default labels associate with the closest switch statement that encloses them. ANSI C requires at least 257 case labels be allowed in a switch statement. The default for Microsoft C is that the Microsoft extensions are enabled.

Switch statements serve as a simple way to write long if statements when the requirements are met. Often it can be used to process input from a user. Below is a sample program, in which not all of the proper functions are actually declared, but which shows how one would use switch in a program.

The switch statement is used to perform different actions based on different conditions. Use the switch statement to select one of many blocks of code to be executed. This is how it works: First we have a single expression n (most often a variable), that is evaluated once. The value of the expression is then compared with the values for each.

The switch statement is an enhancement to the 'if' statement. If you have multiple expressions that need to be evaluated in one shot, then writing multiple 'if' statements becomes an issue. The switch statement is used to evaluate an expression and run different statements based on the result of the expression.

The switch statement tests the variable against a set of constants. The switch statement contains multiple case labels. The switch case must include 'break' keyword to stop the execution of switch case. The default case executes when no case satisfies the expression. A nested switch statement is allowed.
