C-string

A string is a one-dimensional array of characters that can be terminated using a null character (‘\0’). The string or character array is used to manipulate the text such as words or sentences. The \0 (termination character) is the most important in the string as it is the only method to identify the end of the string. A string can be defined as a one-dimensional array of characters; whereas, an array of strings is a two-dimensional array of characters.
