sort()函数是c++、java里对数组的元素进行排序的函数，该函数在c++中包含于algorithm库中。定义和用法 sort()方法用于对数组的元素进行排序。包含于头文件algorithm。函数原型 包含两个参数时，参数分别为需要排序数组开始的地址和结束的地址;包含三个参数时，参数分别为需要排序数组开始的地址，结束的地址和用于比较两...

template<classRandomIt,classCompare >constexprvoidsort( RandomIt first, RandomIt last, Compare comp ); 以一定排序规则排序指定范围内的元素,但是算法不具有稳定性,如果元素的值是相同的话不保证它们的相对顺序保持不变。 参数说明 first , last -要排序的元素范围。
