It may have only been Visual C++ 6.0 or something, but I think I remember needing to add curly braces after a switch's case label to declare variables, is this still true with VS2010 and C++?
ex:
switch( 1 )
{
case 1:
{
int a; //<-- ok
}
break;
case 2:
int b; //<-- not ok?
break;
}I only ask because I'm kind of under the weather and am in the middle of some updates to a project.
Jump to PostNo. You can declare variables in the main function.
int main() { int a, b; <rest of program here> return 0; }Switch statement is a "flow of control" like the if-else statement, while loop, for statement, etc.

Also, with a switch statement. The code will continue to run until a break statement is found or until the end of the switch statement. You do not need additional brackets except the overall brackets that made the switch code block.
switch(c){ // beginning of switch code block
case 1:
dothisfunction();
break;
case 2:
dothatfunction();
break;
default:
cout <<"What are you doing?\n";
} // end of switch code blockWe're a friendly, industry-focused community of developers, IT pros, digital marketers, and technology enthusiasts meeting, networking, learning, and sharing knowledge.
