c++ - 稍后在 {} 中添加 unsigned int 数组

Question

我可以在 C++ 中做这样的事情吗？或者我应该做什么。

unsigned int code[180];

    if ( somethings ) 
    {
      code[] = {3150,1550,400,400,400,1150,450,350,400,400,400,1200,400,400,400,1150,400,400,400,400,400,1150,400,1200,400,1200,400,350,400,1200,400,400,400,1150,400,1200,400,1200,400,350,400,400,400,400,400,400,400,1150,400,1200,400,400,400,1150,400,1200,400,400,400,400,400,1150,400,400,400,400,400,1150,450,350,400,400,400,1200,400,1150,400,400,400,1200,400,1150,400,1200,400,1150,450,1150,400,1200,400,350,450,1150,400,400,400,1150,450,350,400,400,400,400,400,400,400,1150,400,400,400,1200,400,400,400,1150,400,1200,400,1150,400,1200,400,1200,400,350,400,400,400,1200,400,400,400,350,400,400,400,400,400,400,400,1150,400,1200,400,400,400,400,400,1150,400,1200,400,1150,450,1150,400,400,350,1200,450,350,400,1200,400,400,400,350,450,350,400,400,400,1200,400,350,450,1150,400,1000};
      //irsend.sendRaw(code,sizeof(code)/sizeof(int),khz);
    }

我认为您不能在声明后使用 {...} 初始化数组。因此，使用一个临时数组来存储您的内容并将内容 memcpy 到其中(如果这是您的用例)。

unsigned int code[180];
  if ( _SOME_CONDITION_ ) 
  {      

    unsigned int temp1 [] ={3150,1550,400,400,400,1150,450,350,400,400,400,1200,400,400,400,1150,400,400,400,400,400,1150,400,1200,400,1200,400,350,400,1200,400,400,400,1150,400,1200,400,1200,400,350,400,400,400,400,400,400,400,1150,400,1200,400,400,400,1150,400,1200,400,400,400,400,400,1150,400,400,400,400,400,1150,450,350,400,400,400,1200,400,1150,400,400,400,1200,400,1150,400,1200,400,1150,450,1150,400,1200,400,350,450,1150,400,400,400,1150,450,350,400,400,400,400,400,400,400,1150,400,400,400,1200,400,400,400,1150,400,1200,400,1150,400,1200,400,1200,400,350,400,400,400,1200,400,400,400,350,400,400,400,400,400,400,400,1150,400,1200,400,400,400,400,400,1150,400,1200,400,1150,450,1150,400,400,350,1200,450,350,400,1200,400,400,400,350,450,350,400,400,400,1200,400,350,45 0,1150,400,1000};
    //irsend.sendRaw(code,sizeof(code)/sizeof(int),khz);

    memcpy(code, temp1, sizeof(temp1) / sizeof(*temp1));
  } else {
    unsigned int temp2 = {...};
    memcpy(code, temp2, sizeof(temp2) / sizeof(temp2));
  }
