Strings are objects that represent sequences of characters. The standard string
class provides a simple, safe and versatile alternative to using explicit arrays of char
s when dealing with text and other sequences of characters. The C++ string
class is part of the std
namespace and was standardized in 1998.
std::string s;
std::string s(“Hello”);
std::string s = “Hello”;
std::string s1(“Hello”);
std::string s2(s1);
std::string s1(“Hello”);
std::string s2(s1, 0, 4); // Copy 4 characters from position 0 of s1 into s2
std::string s1(“Hello World”);
std::string s2(s1, 5); // Copy first 5 characters of s1 into s2
std::string s(5, ‘a’); // s contains aaaaa
