In Bubble sort, two consecutive elements in a given list are compared and their positions in the given list (array) are interchanged in ascending or descending order as desired. Consider the following series of numbers, which are to be arranged in ascend

sort函数用法例如：int cmp( const int &a, const int &b ){ if( a > b )return 1;else return 0;} sort(a,a+n,cmp);是对数组a降序排序 又如：int cmp( const POINT &a, const POINT &b ){ if( a.x < b.x )return 1;else if( a.x == b.x ){ if( a.y < b.y ...

C++ STL提供了类似C语言中 qsort() 的函数排序,它对向量或数组进行排序,其中数组中的项是随机排列的。 sort() 函数通常需要两个参数,第一个参数是数组/向量开始排序的位置,第二个参数是我们希望数组/向量排序的长度。第三个参数是可选的,可以在我们想按字典顺序对元素排序的情况下使用。 ...

C语言可以使用malloc函数。 C可以使用新操作员。 Malloc函数在C的stdlib中。H头文件和C的cstdlib头文件。 例如: int arraysize scanf(%d,&;arraysize) int*pointer=(int*)malloc(arraysize) 分配arraysize内存空间, pointer指向此内存空间的第一个地址。
