replace,replace_if,replace_copy,repace_copy_if

代码如下：

#include<iostream>
#include<algorithm>
#include<string>
#include<vector>
#include<functional>
using namespace std;
int main(){
	vector<int>v;
	for(int i=0;i<10;++i){
		v.push_back(i);
	}
	replace(v.begin(),v.end(),5,555); //把5换成555
	copy(v.begin(),v.end(),ostream_iterator<int>(cout," "));
	cout<<endl;

	replace_if(v.begin(),v.end(),bind2nd(greater<int>(),5),10086);//把大于五的都换成10086
	copy(v.begin(),v.end(),ostream_iterator<int>(cout," "));
	cout<<endl;

	replace_if(v.begin(),v.end(),not1(bind2nd(modulus<int>(),2)),222);//把偶数换成222
	copy(v.begin(),v.end(),ostream_iterator<int>(cout," "));
	cout<<endl;
	system("pause");
	return 0;
}

#include<iostream>
#include<string>
#include<vector>
#include<algorithm>
#include<functional>
using namespace std;
int main(){
	int a[]={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20};
	vector<int>v(a,a+20);
	replace_copy(v.begin(),v.end(),ostream_iterator<int>(cout," "),10,1000);
	cout<<endl;

	replace_copy_if(v.begin(),v.end(),ostream_iterator<int>(cout," "),not1(bind2nd(modulus<int>(),3)),333);//够能被3整出的换成333
	cout<<endl;

	replace_copy_if(v.begin(),v.end(),ostream_iterator<int>(cout," "),bind2nd(greater<int>(),10),1);
	cout<<endl;
	system("pause");
	return 0;
}
