字符串:
#include <iostream>
#include <cstdio>
#include <string>
int main()
{
using namespace std;
string str1 = "this is a string";
string str2("string");
cout << str1 <<endl;
cout << str2 << endl;
cout << str1.c_str() <<endl;
cout << str2[2] << endl;
//c++11 initiate string
char sc1[] = {"12345678"};
char sc2[] {"abcdefg"};
string str3 = {"12345789"};
string str4 {"abcdefgh"};
//operate string
cout << str1 + str2 << endl;
str1 += str2;
cout << str1 << endl;
//other char
wchar_t title[] = L"string";
char16_t name[] = u"String";
char32_t car[] = U"strings";
//raw string
cout << R"(I am "king" , "\n" , hahaha)" <<endl;
//note the strat and end
cout << R"*_(I (need) end)*_" << endl;
cout << R"_(I (need) end)_" << endl;
cout << R"+_(I (need) end)+_" << endl;
return 0;
}
本文深入探讨了C++中字符串的多种初始化方式,包括传统初始化和C++11新特性,以及字符串的操作方法,如拼接、访问字符等。同时介绍了不同字符类型,如wchar_t, char16_t, 和 char32_t,并展示了如何使用原始字符串字面量。
