Question

我想在c ++中使用常规int从结构中添加一个int。有一个简单的方法吗？我几乎到处搜索，但是在从二进制文件读取数据或者将常规int和struct int一起添加时，没有添加任何两个struct int的内容。

这是我目前所拥有的简单版本。

 struct Add{
    int k;
    };

    int total;

    Add a;

//read in first set of number from binary file
    total += a.k; 
//add up to total, then read in second set of number from binary file.

问题是，当我输出总数时，它只给出了我尝试向其添加int k的最后一个数字，而不是总数。

我要求的实际代码。

struct TaskInit{
    int weight;
};

TaskInit t;

    int totalWeight;

    for (int i = 1; i <= noOfRecords; ++i)
    {
        afile.seekg ((i - 1) * sizeof (TaskInit), ios::beg);
        afile.read (reinterpret_cast <char *>(&t), sizeof (t));

         totalWeight +=  t.weight;

    }
   cout << totalWeight;

Answer 1

struct Add{
    int k;
    };

    int total = 0; // no indeterminate values. always init locals!

    Add a;
   // open your file here. 
  while (inFile >> a.k) {

//read in first set of number from binary file
//add up to total, then read in second set of number from binary file.
      total += a.k;
  }

添加struct int和普通int。 C ++
