is it possible to use the Case with Expression

e.g


Code: 
switch (A)
	{
	case (A > 1 && A < 10):

	break;

	}
 

I'm not sure, but I think you can depending on the compiler. In VB, I can do this, so I think you can do this in VC++ as well. I don't know about other compilers though.

However in VB, I would use
Code: 
case (> 1 and <10)
You don't need to mention A in the case function as A is the variable which you are testing. Why don't you try it out and see?

The above switch statement is invalid in C and C++. The case label must consist of the reserve word, "case" followed by a constant expression and ending with a colon.

"(A > 1 && A < 10)" is not a constant expression.

hello bigdogguru,can you plz provide some useful codes in c using switch case:I am doing like

switch(period){
case 15rintf(lcd_putc,"10%%");
