Problems using MPLAB XIDE [Copy link]

In MPLAB X IDE, can't a switch statement use a variable after a case? switch(Displacement[5]) { case Displacement[0]: Run_Section = 0; // break in acceleration section; Like above, the error is as follows Interrupt.c:297:9: error: case label does not reduce to an integer constant case Displacement[0]: I remember that some compilers can use this, does MPLAB not allow this?

It is not OK to follow a case with a variable, but it is OK to follow a logical condition.

I have the impression that case cannot use variables and can only be judged by integers, so that the compiler can generate efficient optimized code. Otherwise, it is better to use if-else directly.

But you can do this in Keil

Here are the Keil pictures and codes.
