你现所出错提示的意思翻译一下。

ID:914633 · 发表于 2021-7-3 18:18

书上的代码一般前面章节的函数、定义过的变量它会直接拿过来用你抄的过程中重新定义函数定义变量补全代码

我可以很负责任的告诉你，你掉坑里了，要学会读懂程序，抄来的更要仔细读懂，你这个程序看似一大堆错误，实际上就两、三种错误，一个是中英文符号的问题，这个要切记，用上中文的符号肯定出错还不好查，这是网上最常见的对付伸手党的招式，比较好的办法就是下载一个KEIL的配色方案，看颜色就知道哪里不对了，剩下的错误很好排查，你自己找吧，对今后排查错误很有帮助。

谢谢各位回复，出错提示的意思翻译出来，无非是语法错误或是非法字符；但是查不出。改了无效。

给你那么明确的回复了，竟然还搞不定，真要有心的话，你在英文输入法下逐字将所有的符号改一遍过去也不要10分钟，更何况中文符号比英文的更粗一点占位更大一点，还是比较直观的，不信你看看1：和1:有什么差别？你能仅仅选中前面的那个:而不连带着:前后的空白部分吗？
再次建议你采用keil的配色方案吧，符号出错你颜色就不一样了 http://www.51hei.com/bbs/search. ... w=keil+%C5%E4%C9%AB

是啊，显然好多中文符号。
