Section 20.6 Reading Strings from Input

The scanf() function can be used to read a string from the user input using the %s format specifier. By default, reading stops when white space (i.e. a space, return, etc.) is encountered. There are many options to modify this behavior so that the reading stops based on different conditions (if interested: Google).

The below example shows how to read a two words (a first name and a last name) from the user input and store them in corresponding strings.

Investigate 20.6.

Why is the ampersand character & missing in front of firstName and lastName in the above scanf() statement?

Hint.

Remember, a string is really an array of characters (with the null terminator placed at the end). Do you remember what an array variable really stores?.
