创建结构实例数组[C]

问题描述：

我正在为嵌入式系统实验室创建一个有限状态机。编译器（我正在使用ARM的Kiel）抱怨我尝试声明一个struct实例的数组。我做错了什么？创建结构实例数组[C]

我的代码（部分）：

struct State { 
    unsigned long OutCars; 
    unsigned long OutWalk; 
    unsigned long Time; 
    unsigned long Next[8]; 
}; 

typedef const struct State SType; 


SType FSM[11] = { 
    {0x0C, PF1, 100, {goW, goW, waitW, waitW, waitW, waitW, waitW, waitW} }, 
    {0x14, PF1, 50, {goW, goW, goS, goS, goWa, goWa, goWa, goWa} }, 
    {0x21, PF1, 100, {goS, waitS, goS, waitS, waitS, waitS, waitS, waitS} }, 
    {0x22, PF1, 50, {goS, goW, goS, goW, goWa, goW, goWa, goW} }, 
    {0x24, PF3, 100, {goWa, off1, off1, off1, goWa, off1, off1, off1} }, 
    {0x24, OFF, 50, {on1, on1, on1, on1, on1, on1, on1, on1} }, 
    {0x24, PF1, 50, {off2, off2, off2, off2, off2, off2, off2, off2} }, 
    {0x24, OFF, 50, {on2, on2, on2, on2, on2, on2, on2, on2} }, 
    {0x24, PF1, 50, {off3, off3, off3, off3, off3, off3, off3, off3} }, 
    {0x24, OFF, 50, {on3, on3, on3, on3, on3, on3, on3, on3} }, 
    {0x24, PF1, 50, {goWa, goW, goS, goS, goWa, goW, goS, goS} }, 
};

错误消息：

...

TableTrafficLight.c(155): error: #67: expected a "}"

{0x0C, PF1, 100, {goW, goW, waitW, waitW, waitW, waitW, waitW, waitW} },

...

编辑：原来我已经结束我的发言#define用分号。哎呀。学过的知识。关闭括号之前

没有什么错，你已经显示的代码。（当然，你还没有展示如何定义所有这些常量。）我建议将该代码和关联的定义放在一个单独的文件中，然后尝试自行编译该文件。通常，C编译器发出的错误消息是由文件中较早的错误（例如缺少分号）引起的。 – user3386109

编译器错误/警告引用特定的源代码行（此处为155）。你应该总是清楚这是哪一行。 – alk

@alk错误消息下显示的行似乎是数组初始值设定项的第一行。 – user3386109

答

删除最后一个逗号（除去为高亮）：

SType FSM[11] = { 
    {0x0C, PF1, 100, {goW, goW, waitW, waitW, waitW, waitW, waitW, waitW} }, 
    {0x14, PF1, 50, {goW, goW, goS, goS, goWa, goWa, goWa, goWa} }, 
    {0x21, PF1, 100, {goS, waitS, goS, waitS, waitS, waitS, waitS, waitS} }, 
    {0x22, PF1, 50, {goS, goW, goS, goW, goWa, goW, goWa, goW} }, 
    {0x24, PF3, 100, {goWa, off1, off1, off1, goWa, off1, off1, off1} }, 
    {0x24, OFF, 50, {on1, on1, on1, on1, on1, on1, on1, on1} }, 
    {0x24, PF1, 50, {off2, off2, off2, off2, off2, off2, off2, off2} }, 
    {0x24, OFF, 50, {on2, on2, on2, on2, on2, on2, on2, on2} }, 
    {0x24, PF1, 50, {off3, off3, off3, off3, off3, off3, off3, off3} }, 
    {0x24, OFF, 50, {on3, on3, on3, on3, on3, on3, on3, on3} }, 
    {0x24, PF1, 50, {goWa, goW, goS, goS, goWa, goW, goS, goS} }, //remove this comma 
};

变为：

SType FSM[11] = { 
    {0x0C, PF1, 100, {goW, goW, waitW, waitW, waitW, waitW, waitW, waitW} }, 
    {0x14, PF1, 50, {goW, goW, goS, goS, goWa, goWa, goWa, goWa} }, 
    {0x21, PF1, 100, {goS, waitS, goS, waitS, waitS, waitS, waitS, waitS} }, 
    {0x22, PF1, 50, {goS, goW, goS, goW, goWa, goW, goWa, goW} }, 
    {0x24, PF3, 100, {goWa, off1, off1, off1, goWa, off1, off1, off1} }, 
    {0x24, OFF, 50, {on1, on1, on1, on1, on1, on1, on1, on1} }, 
    {0x24, PF1, 50, {off2, off2, off2, off2, off2, off2, off2, off2} }, 
    {0x24, OFF, 50, {on2, on2, on2, on2, on2, on2, on2, on2} }, 
    {0x24, PF1, 50, {off3, off3, off3, off3, off3, off3, off3, off3} }, 
    {0x24, OFF, 50, {on3, on3, on3, on3, on3, on3, on3, on3} }, 
    {0x24, PF1, 50, {goWa, goW, goS, goS, goWa, goW, goS, goS} } 
};

嗯，没有。 C规范特别允许使用逗号。 – user3386109

@ user3386109：“*允许使用逗号。*”仅限于C99。 – alk

试过了，但他现在已经有效了。另外，编译器没什么好说的。谢谢指出，但可能是这个问题。 – proprol
