So if we sort the first column in ascending order the output will be: [[1, 4, 5], [3, 4, 2], [6, 7, 3]] Here we need to define our user-defined comparator function to do the above thing. Like we will take each element of the 2D vector (which is a 1D vector, to be ...
在C语言中,可以使用sort函数对vector进行排序。下面是一个示例代码: #include <stdio.h> #include <stdlib.h> // 比较函数,用于sort函数的第三个参数 int compare(const void *a, const void *b) { return (*(int*)a - *(int*)b); } int main() { int arr[] = {5, 2, 8, 1, 9}; int...
2.编写一个程序,随机产生10个 1∼100 的正整数,利用vector容器存储数据,并用accumulate算法求这10个随机数之和,用sort算法对它们进行排序,用c
vector sort函数 Vectorsort函数是C++中的一种排序函数,它是标准模板库(STL)中的一部分。它可以对STL的容器(container)中的数据进行排序快速、高效地比较、比较和更改大型数据集。它可以用来排序任何数据类型,包括:字符,整数,浮点数,布尔值,对象等。 Vector sort函数提供了一种简单、快速、强大的方式来对容器中的...
然后,我们可以使用这个函数与sort算法一起,对Person对象的std::vector进行排序: std::vector<Person> people = {...};std::sort(people.begin(), people.end(), comparePersons); 在英语口语交流中,你可能会说:“To sort custom types, we need to provide a comparison function that takes two arguments ...
