Parsing strings (C)

(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt)

Examples of strings that can be accepted:

Jill, Allen

Jill , Allen

Jill,Allen

Ex:

Enter input string: Jill, Allen 

(2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts) Ex:

Enter input string: Jill Allen Error: No comma in string. Enter input string: Jill, Allen 

(3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. (2 pts) Ex:

Enter input string: Jill, Allen First word: Jill Second word: Allen 

(4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. (2 pts)
