switch statement problem
i have code like this
char c = pkt_->data[3];
switch (c)
{
case 0x03:
ret="R";
break;
case 0xf6:
ret="F";
break;
case 0xf7:
ret="f";
break;
default:
break;
}
while debugging i can see that value of c is 0xf7, but it is not going to execute that case statement and always going to default case. what could be the problem.

That code should work.
How do you know that it is failing?
Does it work when c is 0x03?
What is your declaration for the variable 'ret' ?

it is not executing case 0xf7:
if i write case -9:, it works. but above code works on linux.

I thought that was a pretty excellent answer. Neither jhance nor myself thought of it immediately. I wonder why nrusinh gave SteH a grade of C.

ret="R";
what is ret? If a char, then you are writing improper code. It should be:
ret = 'R';
