Warning: Expression has no effect
Help please the beginner.
I'm trying to write a simple program:
If button1 and button_2 are pressed, then LED_3 lights up./media/uploads/pvo317/main.cpp
If button3 and button_2 are pressed, then LED_1 lights up.
what's wrong? The compiler produces "Warning: Expression has no effect "READ_KEY" "Warning: Expression has no effect "TEST_KEY_A" "Warning: Expression has no effect "TEST_KEY_B"
BLIM_TEST - working.
