In the previous section,
I have discussed how to use conditional statement in C and C++ language where I
showed only if-else statement. Now I shall show you another powerful keyword
named switch statement to control
program sequence in C and C++.
How
switch statement works
When you need to take a
decision from multiple choices and select only one choice, you can use switch
statement for that case. Say, you need to make a menu in your program. When a
user fulfills a condition, he will get a result and when he fulfills another
condition, he will find another result and so on. To handle this situation
switch is your best friend. Switch
statement works with case keyword. When a particular condition will be
fulfill within switch, the corresponding case statement will be executed like
making switch on or off in your electrical or electronics switch board.
