Hi guyss!! Need a bit of help

Question

I have started C++ and doing pretty well{ I mean I think so } and I want to make a calculator.
For that I want to declare a variable as a string llike we declare integer
if any one of you know this please do tell me.

Answer 1

#include <string>
using namespace std;

//can be declared with or without a value
string stringName = "value";

Answer 2

In c++, you need to include string library using #include <string> for more features on strings.
After including library you can declare string variable as follows -

string var;
var = "hello";

Above lines will declare string variable var and set its value to "hello". You can do same thing in one line as -

string var = "hello";
