顺序表按段删除

设计一个算法，从一给定的顺序表L中删除下标i~j（i<=j，包括i、j）的所有元素，假定i、j都是合法的。

c语言

#include

int deleteElemij(int sqList[], int &length, int i,int j)
{
	if (i<0 || j>length - 1)
		return 0;
	int c = j - i + 1;

	for (int n = i-1; n < length ; ++n)
		sqList[n] = sqList[n + c];
	length = length - c;
	return 1;
}

int main()
{
	int A[] = {1,2,3,4,5,6,7,8,9,10};
	int length = 10;
	deleteElemij(A, length, 3, 5);
	for (int i = 0; i < length; ++i)
		printf("%d ",A[i]);
	return 0;
}

c++

#include
using namespace std;
void del(int arr[],int &length,int i,int j)
{
	int k, delta;
	delta = j - i + 1;
	for (k = j + 1; k < length; ++k)
		arr[k - delta] = arr[k];
	length = length - delta;
}
int main()
{
	int A[] = { 1,2,3,4,5,6,7,8,9,10 };
	int length = 10;
	del(A, length, 3, 5);
	for (int i = 0; i < length; ++i)
		cout << A[i] << " ";
	cout << endl << length;
	return 0;
}
