问题描述

在c ++中是否有类似string.contains()的东西?

Is there anything like string.contains() in c++?

推荐答案

我无法确切回答，因为您的帖子中有关于除了名称，"string.contains()"的作用是什么.我建议看一下std :: string :: find()看看是否合适.

干杯，

I can''t answer definitively as there''s clue in your post as to what "string.contains()" does apart from the name. I''d suggest looking at std::string::find() and see if that fits the bill.

如果使用boost libary，则可以这样使用包含".
示例:
#include< boost/algorithm/string.hpp>
使用名称空间std;
使用命名空间boost;
字符串str1("hello");
字符串str2("el");
bool结果= contains(str1，str2);

在boost :: algorithm中找到有用的东西.

干杯.

If you use boost libary, you can use "contains" like this.
Example:
#include <boost/algorithm/string.hpp>
using namespace std;
using namespace boost;
string str1("hello");
string str2("el");
bool result = contains(str1, str2);

Find something usefull in boost::algorithm.

Cheers.

我记得，在大学一年级实践考试中，我不得不开发一个函数来找出所需的字符串是否存在.

为什么问这个问题?

如果是家庭作业，最好自己动手做.

I can remember, in university first year practical exam I had to develop a function to find out whether the desired string exists or not.

Why are you asking this question?

if it is a homework better do it yourself.
