Question

I’d like to add an int from a struct with a regular int in c++. Is there an easy way to do it? Ive searched pretty much everywhere but theres nothing on adding either two struct ints while reading in data from a binary file or adding a regular int and a struct int together.

This is the simple version of what I currently have.

 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.    

The problem is, when I output total, it only gives me the last number I tried adding int k to it and not the total.

My actual code as requested.

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;

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;
  }
