针对你遇到的“error: #20: identifier "bool" is undefined”错误,以下是一些可能的解决步骤: 确认编程语言和上下文: 首先确认你正在使用的编程语言。如果是C语言,bool类型不是内建类型,需要通过包含特定的头文件来定义。 查看出现错误的代码段,确认bool类型的使用环境。 包含定义bool类型的头文件: 如
usb-driver\STM32_USB-FS-Device_DriverV3.1.1\src\usb_core.c(45): error: #20: identifier "FALSE" is undefined 在stm32f103.h中添加 typedef enum {FALSE = 0, TRUE = !FALSE} bool; 就没有错误了

more point, the return type of deleteNode is a bool, it has a value of true or false It not be compared with NULL, in fact it is sufficient to just put: if !name.deleteNode(inputOne, inputTwo, inputThree) ) Oct9, 2013 at 6:19am elite zero (106) yeah i changed that...
