1.string基础操作(包括初始化,遍历,替换,增删改查等基础操作)
2.stack基础操作(包括出栈,入栈,栈顶元素的获取和弹出)
3.list 基础操作(如何高效地进行插入删除操作)
4.deque基础操作(排序和查找)
5.multiset基础操作(解决了set不能同一个值出现的问题)
示例代码1 string基础操作
#include
using namespace std;
void main11()
{
//初始化方式
string s1 = "aaaa";
string s2("aaaa");
string s3 = s2;
string s4 (10, 'a');
cout << "s1:" << s1 << endl;
cout << "s2:" << s2 << endl;
cout << "s3:" << s3 << endl;
cout << "s4:" << s4 << endl;
}
//string 的遍历
void main22()
{
//1 数组方式
string s1 = "asddfff";
for (int i = 0; i < s1.length(); i++)
{
cout << a[i] << "";
}
//2 迭代器
for (string::iterator it = s1.begin(); it != s1.end(); it++)
{
cout << *it << "";
}
cout << endl;
for (int i = 0; i < s1.length(); i++)
{
cout << s1.at(i) << "";//抛出异常
}
cout << endl;
}
//字符指针和string 转换
void main33()
{
string s1 = "aaa";
printf("s1:%s\n", s1.c_str());
//s1的内容拷贝到buf中
char buf1[128];//分配内存
s1.copy(buf1, 3, 0);//只会拷贝三个字符,不会变成c风格的字符串
cout << "buf1:" << buf1 << endl;
}
//连接字符串
void main44()
{
string s1 = "aaa";
string s2 = "bbb";
s1 = s1 + s2;
cout << s1 << endl;
string s3 = "999";
string s4 = "4444";
s3.append(s4);
cout << "s3:" << s3 << endl;
}
//字符串的查找和替换
void main55()
{
string s1 = "sdf 555 sdgdf4564dfgtysrtw4tgrsghtyju7io869i7eu5ewtgrs";
int index = s1.find("555", 0);
cout << "index:" << index << endl;//位置下标,从0开始
int offindex = s1.find("555", 0);
while (offindex != string::npos)//出现的次数,数组下标
{
cout << "offindex" << offindex << endl;
offindex = offindex + 1;
s1.find("555", offindex);
}
//案例2 替换
string s3 = "aaa bbb ccc";
s3.replace(0, 3, "AAA");
cout << "s3" << s3 << endl;
offindex = s1.find("555", 0);
while (offindex != string::npos)//出现的次数,数组下标
{
cout << "offindex" << offindex << endl;
s1.replace(offindex, 3, "555");
offindex = offindex + 1;
s1.find("555", offindex);
}
cout << "s1替换后的结果:" << s1 << endl;
}
//区间删除和插入
void main66()
{
string s1 = "hello1 hello2 hello1";
string::iterator it = find(s1.begin(), s1.end(), '1');
if (it != s1.end())
{
s1.erase(it);
}
cout << "s1删除以后的结果" <<s1<< endl;
s1.erase(s1.begin(), s1.end());
cout << "s1全部删除:" << s1 << endl;
cout << "s1长度:" << s1.length() << endl;
}
void main77()
{
string s1 = "AAAbbb";
//函数的入口地址 函数对象 预定义的函数对象
transform(s1.begin(), s1.end(), s1.begin() ,tuopper);
cout << s1 << endl;
string s2 = "AAAbbb";
transform(s1.begin(), s1.end(), s2.begin(), tulower);
cout << "s2" << s2 << endl;
}
void main()
{
main11();
main22();
main33();
main44();
main55();
main66();
cout << "hello..." << endl;
system("pause");
return;
} 示例代码2 stack基础操作
#include
using namespace std;
#include"stack"
//栈的模型
void main11()
{
stack s;
//入栈
for (int i = 0; i < 10; i++)
{
//出栈
while (!s.empty())
{
int tmp = s.top();//获取栈顶元素
cout << tmp << "";
s.top();//弹出栈顶元素
}
}
class Teacher
{
public:
int age;
char name[32];
public:
void printT()
{
cout << "age:" << age << endl;
}
};
void main22()
{
Teacher t1, t2, t3;
t1.age = 31;
t2.age = 32;
t3.age = 33;
stack s;
s.push(t1);
s.push(t2);
s.push(t3);
while (!s.empty())
{
Teacher tmp = s.top();//获取栈顶元素
tmp.printT();
s.top();//弹出栈顶元素
}
void main33()
{
Teacher t1, t2, t3;
t1.age = 31;
t2.age = 32;
t3.age = 33;
stack s;
s.push(&t1);
s.push(&t2);
s.push(&t3);
while (!s.empty())
{
Teacher *p = s.top();//获取栈顶元素
p->printT();
s.top();//弹出栈顶元素
}
void main()
{
main11();
main22();
main33();
cout << "hello..." << endl;
system("pause");
return;
} 示例代码 3 list 基础操作
/*
1 list是一个双向列表容器,可以高效地进行插入删除操作(左闭右开)
2 list不可以随机存取元素,所以不支持at.(pos)函数与[]操作符
#include
*/
#include
using namespace std;
#include"list"
void mian11()
{
list < int> l;
cout << "list的大小" << l.size() << endl;//测试
for (int i = 0; i < 10; i++)
{
l.push_back(i);//尾插法
}
cout << "" << l.size() << endl;
list::iterator it = l.begin();//迭代器
while (it != l.end())
{
cout << *it << "";
it++;
}
it = l.begin();//list不能随机访问
it++;
it++;
it++;
list.insert(it, 100);//100插入在哪里?
for (list::iterator it = l.begin(); it != l.end(); it++)
{
cout << *it << endl;
}
//结论:链表的结点index序号是从0号位置开始的.在3号位置插入元素,原来的三号位置,变成4号位置.
}
void main33()
{
list < int> l;
cout << "list的大小" << l.size() << endl;//测试
for (int i = 0; i < 10; i++)
{
l.push_back(i);//尾插法
}
cout << "" << l.size() << endl;
list::iterator it1 = l.begin();
list::iterator it2 = l.begin();
it2++;
it2++;
it2++;
l.erase(it1, it2);
for (list::iterator it = l.begin(); it != l.end(); it++)
{
cout << *it << endl;
}
cout << endl;
//插入和删除
l.insert(l.begin(), 100);
l.insert(l.begin(), 100);
l.insert(l.begin(), 100);
l.erase(l.begin());
l.remove(100);
}
void main()
{
//main11();
///main33();
cout << "hello..." << endl;
system("pause");
return;
}
示例代码4 deque基础操作
#include
using namespace std;
#include"deque"
#include"algorithm"
void printD(deque&d)
{
for (deque::iterator it = d.begin(); it != d.end(); it++)
{
cout << *it << endl;
}
}
void main11()
{
deque d1;
d1.push_back(1);
d1.push_back(3);
d1.push_back(5);
d1.push_front(-11);
d1.push_front(-33);
d1.push_front(-55);
cout << "头部元素" << d1.front << endl;
cout << "尾部元素" <<d1.back<< endl;
printD(d1);
d1.pop_front();
d1.pop_back();
printD(d1);
//查找-33数组下标的值
deque::iterator it = find(d1.begin(), d1.end(), -33);
if (it != d1.end())
{
cout << "-33数组下标是" << distance(d1.begin(), it) << endl;
}
else
{
cout << "没有找到值为-33的元素" << endl;
}
}
void main()
{
main11();
cout << "hello..." << endl;
system("pause");
return;
} 示例代码5multiset基础操作
#include

#include
#include"list"
#include"set"
void main11()
{
multiset setl;
int tmp = 0;
printf("请输入multiset集合的值:");

printf("请输入multiset集合的值:");
scanf("&d", &tmp);
}
for (multiset::iterator it = setl.begin(); it != setl.end(); it++)

cout << *it << " ";
}
cout << endl;
while (!setl.empty())
{
multiset::iterator it = setl.begin();
cout << *it << " ";
setl.erase(it);
}
