string - C++ Users
Strings are objects that represent sequences of characters. The standard string class provides support for such objects with an interface similar to that of a standard container of bytes, but adding features specifically designed to operate with strings of single-byte characters. The string class is an instantiation of the basic_string class template that uses char (i.e., bytes) as its ...

std::basic_string - cppreference.com
The class template basic_string stores and manipulates sequences of character-like objects, which are non-array objects of TrivialType and StandardLayoutType.The class is dependent neither on the character type nor on the nature of operations on that type. The definitions of the operations are supplied via the Traits template parameter - a specialization of std::char_traits or a compatible ...

std::string class in C++ - GeeksforGeeks
As strings are represented as objects, no array decay occurs. There is a threat of array decay in the case of the character array. Strings are slower when compared to implementation than character array. Implementation of character array is faster than std:: string. String class defines a number of functionalities that allow manifold operations ...

c++ - How to trim a std::string? - Stack Overflow
What you are doing is fine and robust. I have used the same method for a long time and I have yet to find a faster method: const char* ws = " \t\n\r\f\v"; // trim from end of string (right) inline std::string& rtrim(std::string& s, const char* t = ws) { s.erase(s.find_last_not_of(t) + 1); return s; } // trim from beginning of string (left) inline std::string& ltrim(std::string& s, const char ...

5.7 — Introduction to std::string – Learn C++ - LearnCpp.com
In lesson 5.2 -- Literals, we introduced C-style string literals: #include <iostream> int main() { std::cout << "Hello, world!"; // "Hello world!" is a C-style string literal. return 0; } While C-style string literals are fine to use, C-style string variables behave oddly, are hard to work with (e.g. you can’t use assignment to assign a C-style string variable a new value), and are dangerous ...

std::string - C++ standard library - Cprogramming.com
String concatenation will work as long as either of the two strings is a C++ string--the other can be a static string or a char*. String Comparisons One of the most confusing parts of using char*s as strings is that comparisons are tricky, requiring a special comparison function, and using tests such as == or < don't mean what you'd expect.
