I'm about to hit the screen with my keyboard as I couldn't convert a char to a string, or simply adding a char to a string.
I have an char array and I want to pick whichever chars I choose in the array to create a string. How do I do that?
string test = "oh my F**king GOD!"
const char* charArray = test.c_str();
string myWord = charArray[0] + charArray[4];
thats how far I got with it. Please help.
string myWord;
myWord.push_back(test[0]);
myWord.push_back(test[4]);
You don't need to use c_str() here.
basic_string& operator=(charT c). I think I would use that. Like, myWord += test[0].
+ in the function declaration?no need to convert to c_str just:
string test = "oh my F**king GOD!";
string myWord;
myWord += test[0];
myWord += test[4];
Are you restricted in some way to use C++ functions only? Because, for this purpose I use the old C functions like sprintf
You need to also need to remember that a C++ string is quite similar to a vector, while a C string is just array of chars. Vectors have an operator[] and a push_back method. Read more here You use push_back and do not convert to c string.
So your code would look like this:
string test = "oh my F**king GOD!"
string myWord;
myWord.push_back(test[0]);
myWord.push_back(test[4]);
operator[].
string myWord; myWord += charArray[0]; myWord += charArray[4];Cat PlusPlus's way is better, I'm just saying that you can use concatenation for that too.
