Question

我可以在c ++中做这样的事情，或者我该怎么做。

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);
    }

Answer 1

我不认为你可以在声明后使用{...}初始化数组。因此，使用临时数组来存储您的内容并将内容存储到其中（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));
  }

Answer 2

因为你标记了这个c ++，我建议：

vector<int> code;

if( condition_1 )
    code = { 3,7,8 };
else if( condition_2 )
    code = { 9,11,34 };

等

它需要c ++ 11来编译

Answer 3

提前设置代码：

unsigned int 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};

if (strcmp((char*)data,"off") == 0) 
{
    // do stuff with the code here
    //irsend.sendRaw(code,sizeof(code)/sizeof(int),khz);
}

Answer 4

此

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};

是一个初始化，在声明后你不能在C ++中做这样的事情。正确的方法是：

const int code_if[] = { /* your numbers here */ };
int code[];
if ( /* something */ ) {
    code = code_if;
}

如果你真的需要移入数组，那么你应该像其他人已经建议的那样使用memcpy（）。

稍后在{}中添加unsigned int数组
