稍后在{}中添加无符号整型数组

add unsigned int array in {} later

本文关键字：添加 无符号 整型 数组      更新时间：2023-10-16

我可以在c++中做这样的事情吗?或者我应该怎么做? 

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);
    }

我不认为你可以使用{…}。因此，使用临时数组来存储内容并将内容记忆(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));
  }

既然你标记了这个c++，我建议:

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

等。

需要c++11编译

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);
}

This

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};

将是一个初始化，而你不能在c++中做这样的事情声明之后。正确的方式应该是这样的:

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

如果您确实需要在数组中移动，那么您应该像其他人已经建议的那样使用memcpy()。
