My 'else' statement is not working. Anyone know why?

It appears to me like a couple of your if statements do not have closing brackets. This could be the problem.

Your else if statements have no closing curly brackets

You’re actually missing 2 closing curly brackets at the end… ones for your while loop and task main.

Where should i add the brackets?

#6

Put the 2 closing curly brackets at the very bottom of the code. They correspond to the task and the while loop. All of your if and if/else have corresponding open and close brackets so they’re good.

#7

Others have done an excellent job of helping out. For anyone else having a related problem, make sure that all of your starting curly bracket and parantheses have a corresponding ending curly bracket or paranthesis. A fast way to check is by putting your cursor next to the curly bracket - your IDE should automatically highlight the corresponding one in your code.

Also, a note about debugging. If you run your code and see an error, oftentimes the error explains what is happening. When I ran your code, for example, I see the following message:

src/main.cpp:33:2: note: to match this '{'
        {       motor[motorLEFT] = vexRT[Ch3];
        ^
src/main.cpp:69:4: error: expected '}'
                }
                 ^

Even though the exact wording may be a bit confusing at times, it’s usually possible to get a good idea of what’s causing the problem. Here, it seems like my opening curly bracket on line 33 expects a closing curly bracket, which is exactly what others identified.
