上面的代码会报initializer element is not constant 错误，错误原因是：

C语言初始化一个全局变量或static变量时，只能用常量赋值，不能用变量赋值！(错误就在void* v_p = p_a)

解决办法如下：定义成局部变量就OK了。

#include <stdio.h>
int a = 1314; 
int*  p_a = &a; 
int main(void) {
    void* v_p = p_a;
    return 0;
                            
Initializer provides no value for this binding element and the binding element has no default value
                            
 引起错误的TypeScript代码：test(){    const a = () => ({ a , b = 2 } = {}): number => 11;  }该编译错误的解决方法1test(){    const a = () => ({ a , b = 2 }:any = {}):
