您可以这样使用比较器函数: vector<string> v = {"345366", "029323", "38239"};std::sort(v.begin(), v.end(), [](const std::string &s1, const std::string &s2) -> bool { return std::atoi(s1.c_str()) > std::atoi(s2.c_str()); });for(auto i : v) cout << i << en...
A temporary vector that this function doesn’t use. Passnil. __N The number of elements in the vector. __Order A value that specifies the sort order. Pass1to specify ascending order, or-1for descending order. Discussion The following code sorts the indices into an array in ascending order...
std::sort(myvector.begin(), myvector.end(), std::greater<int>()); // descending is to use std::greater() std::cout << "myvector contains:"; for (std::vector<int>::iterator it = myvector.begin(); it != myvector.end(); ++it) ...

BOOL Sort( int wOption = SORT_ASCENDING, BOOL bMissingValuesSmall = TRUE, vector<uint> & vnIndices = NULL, SORTCNTRL cntrl = 0 ) ParameterswOption [input] Set the sorting order and way. Default is SORT_ASCENDING. Combination of the following bits: SORT_DESCENDING, // descending sort ...
myvector contains: 12 26 32 33 45 53 71 80 3个参数的情况 sort(first,last,comp); 第三个参数comp主要用来指明排序顺序,即升序还是降序。 比如在数组中: // C++ program to demonstrate descending order sort using // greater<>(). #include <bits/stdc++.h> using namespace std; int main() {...
由于你的问题是关于“c排序方法sort”,我将基于C++的 std::sort 函数来回答,因为这是在C系语言中广泛使用的标准排序方法。 1. 解释C++中的排序方法 std::sort std::sort 是C++ STL中的一个算法,用于对容器(如数组、std::vector 等)中的元素进行排序。它使用高效的排序算法(通常是快速排序、堆排序或插入...
'descend' results in descending order The MODE option is not valid for lexical sorting. The result is in Y which has the same shape and type as X [Y,I] = CSORT(X,METHOD,DIM,MODE) also returns an index matrix I. If X is a vector, then Y = X(I). ...
