and i want to know to call it using switch...

the ic that i used is 16f877a

I'm not sure what 'void' has to do with it. All it does it tell the compiler the function after it does not return a value.
When you say 'combine two programs' do you mean two functions, within the same program or functions in a different '.C' programs?

In either situation, the switch command takes a parameter which you use to decide which exit from the statement you intend to take. Within the switch command you have either 'case' or 'default' statements. There should only be one 'default', it's the exit taken if all the 'case' checks fail. Each case has a condition which if true, makes the following code execute, if false, the program looks for the next 'case' or 'default' statement to check instead. You can run any code within a case statement, including calls to other functions.

You didn't answer my original question.

Basically, a switch/case structure works the same as several "if (something is true) do ThisFunction() ;" statements, the difference is that the 'case' value must be a constant and that you can use 'default' as a catch-all if all the previous 'case' values failed to match. For example:

switch (MyValue)
{
case 1: FunctionMyValueWas1(...) ;
case 2: FunctionMyValueWas2(...) ;
case 3: FunctionMyValueWas3(...) ;
default: FunctionMyValueWasSomethingElse(...) ;
}

As in all 'C' functions, you can group several statements together between { and } so more than one instruction can execute per case match.
It is also common to see 'break' statements inside 'case' sections to skip the remaining checks and go straight to the end of the switch function.

to excel at the highest level, you have to excel at the basics first.

in your case, if you cannot express yourself clearly, I would suggest that you stop whatever you are doing and take some basic classes in composition and comprehension.
