Is if(TRUE) a good idea in C?

Question

In the C programming language, it is my understanding that variables can only be defined at the beginning of a code block, and the variable will have the scope of the block it w

Answer 1

Since you can just make the scope block without the if, that's a better idea.

void foo() {
     ... Do some stuff ...
     {
         char a;
         int b;
         ... Do some more stuff ...
     }
     ... Do even more stuff ...
}
