Strings

In all programs seen until now, we have used only numerical variables, used to express numbers exclusively. But in addition to numerical variables there also exist strings of characters, that allow us to represent successions of characters, like words, sentences, names, texts, et cetera. Until now we have only used them as constants, but we have never considered variables able to contain them.
In C++ there is no specific elemental variable type to store strings of characters. In order to fulfill this feature we can use arrays of type char, which are successions of char elements. Remember that this data type (char) is the one used to store a single character, for that reason arrays of them are generally used to make strings of single characters. LEARN MORE>>
