Cout按降序排列C++

Question

我需要帮助。我正在编写这个程序，需要计算.csv文件中两个整数之间的差异。找出差异是很容易的，但是当我列出差异列表时，它们没有特定的顺序。我想挑选出具有最高价值的差异和特别的结果。我会怎么做呢？

double diff; 
    int astate; 

    string line8; 
    ifstream myfile8 ("elect12.csv"); 
    //cout << endl << "Total Popular Votes for Other Candidates: "; 
    while (getline (myfile8, line)) 
    { 
     istringstream iss(line); 
     int a, b, c, d, e; 
     if (!(iss >> a >> b >> c >> d >> e)) //{ break; } 
     diff = (a-b); 
     diff = diff/d; 
     diff = diff*100; 
     astate = diff;   
     /*cout << "Obama's best state was " << line8 << ", where he won by " << diff << " points." << endl;*/ 
     cout << astate << endl; 

将差值换算成百分比。现在，& b之间的所有差异正在返回。我如何才能返回最大的差异？

对不起，如果这没有意义。

比较与以往最大的不同电流差（存储在初始化变量astate），如果它是比以前更大的规模最大，然后分配。循环后打印astate的值。
