10_36.cpp

10个比较经典的C++程序。初学者就先多学习学习别人吧。

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
int main()
{	vector<int> iVector1(5);	vector<int> iVector2(5);	vector<int> iVector3(10);
	for (int i = 0; i < 5; ++i) 	iVector1[i] = 3 * i;
	for (i = 0; i < 5; ++i)		iVector2[i] = 1 + 3 * i;
	cout<<"iVector1 is: ";
	copy(iVector1.begin(),iVector1.end(),ostream_iterator<int>(cout," "));
	cout<<"\niVector2 is: ";
	copy(iVector2.begin(),iVector2.end(),ostream_iterator<int>(cout," "));
	//使用通用算法Merge合并向量iVector1和iVector2内容，并放在向量iVector3中
	merge(iVector1.begin(), iVector1.end(),iVector2.begin(), iVector2.end(), iVector3.begin());
	cout<<"\niVector3 is: ";
	copy(iVector3.begin(),iVector3.end(),ostream_iterator<int>(cout," "));
	for (i = 0; i < 5; ++i)	iVector3[i] = iVector1[i];
	for (i = 0; i < 5; ++i)	iVector3[i + 5] = iVector2[i];
	//使用通用算法inplace_merge合并两个有序区间得到有序向量iVector3
	cout<<"\nAfter sorted, iVector3 is: ";
	inplace_merge(iVector3.begin(), iVector3.begin() + 5,iVector3.end());
	copy(iVector3.begin(),iVector3.end(),ostream_iterator<int>(cout," "));
	return 0;
