I deliberately made two mistakes, but the program didn't report an error when I compiled it?! [Copy link]

I deliberately made two mistakes, but the program did not report an error when I compiled it? ! In the definition of stm32f10x.h, line 10, #define GPIOBCRL *(unsigned int *)(GPIOB_BASE +0X00) line 24, uint32 CRL; I defined CRL. Question 1: In mail.c, I deliberately made the label wrong as: GPIOBCRL2 in line 16. In line 22, I deliberately made the label wrong as: GPIOB->CR. The program did not report an error when I compiled it? ! Question 2: In stm32f10x.h, I defined the structure #define GPIOB ((GPIO_TypeDef *) GPIOB_BASE) but in mail.c, after I wrote GPIOB->, the element options in the structure did not pop up automatically? ! Normally, after writing the right arrow, the element options in the structure should pop up automatically? What's going on? The original program is here. 12.28.rar (228.25 KB, downloads: 0)

Let's make a guess. If there is no error, it means that it is defined somewhere else, but you don't know it.

Is the code optimized? Can I run to the wrong place during debugging?

I suggest you consolidate your C basics twice.

Why is there an error? Your main.c is not saved. . .

Where can I see that there is no save? ?

Change else if to #elif , that's it, there's no # in the front. Thanks for everyone's responses.
