Strings are used for storing text/characters. Unlike many other programming languages, C does not have a String type to easily create string variables. Instead, you must use the char type and create an of characters to make a string in C.
char greetings[] = "Hello World!"; // a string stored in greetings array.
Note that you have to use double quotes (""). To write a string.
To output the string, you can use the printf() function together with the format specifier %s to tell C that we are now working with strings:
char greetings[] = "Hello World!";
printf("%s", greetings);
All the array actions can be performed because it's an array of chars.
We can create a string with a set of characters.
char greetings[] = {'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd', '!', '\0'};
printf("%s", greetings);
Why do we include the **\0** character at the end? This is known as the "null terminating character", and must be included when creating strings using this method. It tells C that this is the end of the string.
The difference between the two ways of creating strings is that the first method is easier to write, and you do not have to include the \0 character, as C will do it for us.
We should note that the size of both arrays is the same: They both have 13 characters (space also counts as a character by the way), including the \0 character.
