Typically, rather than dealing with individual characters, we want to work with complete words, sentences, and texts, which are composed of a sequence of characters.

One way to do that is to use an array of char's like this:

cpp

main

copy
1234567
#include <iostream> int main() { char word[10] = {'C', 'o', 'd', 'e', 'f', 'i', 'n', 'i', 't', 'y'}; std::cout << word << std::endl; }

You can see that initialization is quite tricky. Additionally, to add something to this text, you will need to redefine the array with more allocated memory. Fortunately, in C++, there is a string class that makes this process much easier.

So you can assign to a string any text within double quotes " ". Also, adding more text to a string is as easy as using the .append() method. Here is an example:

cpp

main

copy
12345678910
#include <iostream> int main() { std::string word = "Codefinity"; std::cout << word << std::endl; word.append(".com"); std::cout << word << std::endl; }

Besides .append(), there are many other methods of a string to allow you efficiently operate with text data. Here is the table with some. They will be discussed in more detail in later chapters.

Task

  • Create a string variable and store the name 'Alex' in it.
  • Output its value to the console.
