有的内置函数需要添加头文件,请自行搜索增加记忆
//int->string #includeint x1 = 312; string s1 = to_string(x); cout << s1 << endl;
//string->int #includestring s2 = "123456"; int x2 = std::stoi(s2); cout << x2 << endl;
//char->string char c[80] = "1a2b3d4d"; string s3 = c; cout << s3 << endl;
//string->char string s4 = "qwertyuiop"; char *c2 = new char[80]; strcpy(c2, s4.c_str()); cout << c2 << endl; delete c2; c2 = nullptr;
//char->int #includechar c[80] = "258963"; int x3 = atoi(c); cout << x3 << endl;
//int->char 曲线救国: int->string->char
