Cout按降序排列C++
问题描述:
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?Cout按降序排列C++
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。
答
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。
+1
@DominickAlcantara类似的东西,但也许'diff> astate'。 –
+0
是否意味着使用 if(astate> diff)? –
cout内循环是有罪的 –
你必须保存最大的差异yoursef –
并在外侧的循环,显示它 –
