Strings

As we mentioned before strings are used for storing text. Let’s explore some useful functions using this type of variables.

To concatenate 2 (or more) lines to store the result in the new variable, use the operator +:


              1234
            
string a = "Hello ";
string b = "World";
string c = a + b;
cout << c;

String variables contain functions that help perform certain operations on them.

For example, you can find the length of the string variable using the built-in function .length():


              12
            
string a = "Hello user!";
cout << a.length();

For finding the length of the line you can use the funtion .size(): a.size().

You can also concatenate strings using the built-in function .append():


              12
            
string a = "Hello ";
cout << a.append("everyone!");
