关于char p[] = "hello world"; char *p = "hello world";

char p[] = "hello world";      "hello world"为栈内存上，在起生命周期内可修改，一般不可被用return


char *p = "hello world";    "hello world" 位于静态存储区,不可修改

char a[] = "hello world";        char *p  = a;        cout<< sizeof(a) << endl;   // 12字节        cout<< sizeof(p) << endl;  // 4字节

 

      

void Func(char a[100])        {               cout<< sizeof(a) << endl;   // 4字节而不是100字节 }
