C++ 如何显示数组中的最高值
我写的代码有问题。我试图在void函数中获得数组的最大值,但在编译器中得到的只是第四个数组的值,而不管其他值如何。 所以现在如果我输入40,30,20,10,它将赋值10作为最高值。有人能解释一下我做错了什么吗C++ 如何显示数组中的最高值,c++,arrays,C++,Arrays,我写的代码有问题。我试图在void函数中获得数组的最大值,但在编译器中得到的只是第四个数组的值,而不管其他值如何。 所以现在如果我输入40,30,20,10,它将赋值10作为最高值。有人能解释一下我做错了什么吗 #include <iostream> #include <iomanip> #include <string> #include <string.h> using namespace std; string divName[4] =

cout问题在于比较语句中额外的分号:
if (sales[i] > highest); // <<< This semicolon
{
highest = sales[i];
division = i;
}
if(sales[i]>highest);//在findHighest函数中不需要使用两个变量。它只能与一个变量一起使用
void findHighest(double sales[4])
{
int maxIndex = 0;
for (int i = 1; i < 4; i++)
{
if (sales[maxIndex] < sales[i])
maxIndex = i;
}
cout << std::endl;
cout << fixed << setprecision(2) << "The " << divName[maxIndex] << " division had the highest sales this quarter." << std::endl << "Thier sales were $" << maxIndex;
cout << std::endl;
}
void findHighest(双倍销售额[4])
{
int maxIndex=0;
对于(int i=1;i<4;i++)
{
if(销售[maxIndex]<销售[i])
maxIndex=i;
}
这不能解决问题-如果你看看他是如何使用返回值的,他会将返回值放入数组中。Sales
是一个本地问题。这个问题似乎离题了,因为它是由输入错误引起的。请参阅此语句if(Sales[i]>最高)是的,它现在工作得很好。我不敢相信我错过了这么小的东西。非常感谢!
