如何在ASC和DESC模式下对C++数组进行排序？

Question

我有这个数组:

array[0] = 18;
array[1] = -10;
array[2] = 2;
array[3] = 4;
array[4] = 6;
array[5] = -12;
array[6] = -8;
array[7] = -6;
array[8] = 4;
array[9] = 13;

如何在C++中以asc/desc模式对数组进行排序？

Answer 1

要按升序对数组进行排序,请使用:

#include <algorithm>

int main()
{
   //...
   std::sort(array, array+n); //where n is the number of elements you want to sort
}

要按降序排序,请使用

#include <algorithm>
#include <functional>  

int main()
{
   //...
   std::sort(array, array+n, std::greater<int>());
}
