C++ 删除线性表中元素：使用 Delete 函数高效移除指定范围的值

#include <stdio.h> #define MAXSIZE 20 typedef int ElementType; typedef int Position; typedef struct LNode List; struct LNode { ElementType Data[MAXSIZE]; Position last; / 线性表的长度*/ }; List Delete( List &L, ElementType minD, ElementType maxD ); List ReadInput();

List Delete( List &L, ElementType minD, ElementType maxD ) { int i, j; for(i = 0, j = 0; i <= L->last; i++) { if(L->Data[i] >= minD && L->Data[i] <= maxD) { L->Data[j] = L->Data[i]; j++; } } L->last = j - 1; return L; }

List ReadInput() { int num,i,temp; List L = new struct LNode; scanf("%d",&num); for(i=0;i<num;i++) { scanf("%d",&(L->Data[i])); } L->last = num-1; return L; }

void PrintList( List L ) { for(int i=0;i<=L->last;i++) { printf("%d ",L->Data[i]); } }

int main() { List L; ElementType minD, maxD; int i; L = ReadInput(); scanf("%d %d", &minD, &maxD); L = Delete( L, minD, maxD ); PrintList( L ); return 0; }
