The getchar function in the stdioh library reads a single c

The getchar ) function in the stdio.h library reads a single character from the user and returns it as a value of type char). The ctype.h header file contains several useful functions for working with char values, including the following: . isspace (c) -Returns true if the character c is any kind of space (including a newline or a tab character) and false otherwise. isalpha (c) -Returns true if the character c is a letter (uppercase or lowercase) and false otherwise. . isdigit (c) -Returns true if the character c is a digit (0 through 9) and false otherwise. islower (c)-Returns true if the character c is a lowercase letter and false otherwise. isupper (c) -Returns true if the character c is an uppercase letter and false otherwise. . tolower (c) -Returns the lowercase version of the provided character c. toupper (c) -Returns the uppercase version of the provided character c. A syntactically correct C program has been provided in the file A4P2_2016_Template.c (posted on CourseSpaces). As written, the template program reads a single line of text from the user and prints each character on a line by itself. The result of a sample run of the unmodified template is shown below Enter a line of text: Hello World Character: H Character e Character: 1 Character: 1 Character: o Character: (space) Character: W Character: o Character r Character 1 Character: d
