What is the purpose of the control string in a scanf function?

What is control string?

Control strings are also known as format specifiers. They are used in formatted input and output operations of the data. Remember, format specifiers are used for formatting the data, for example, in printf() and scanf() .

In what ways does the control string within a printf function differ from the control string within a scanf function?

The control string of scanf() is different than the control string of printf(). Both scanf() and printf() are control strings of C language. The scanf() function is an input command whereas printf() is an output command.

The C language does not provide an inbuilt data type for strings but it has an access specifier “ \%s ” which can be used to directly print and read strings. You can see in the above program that string can also be read using a single scanf statement.
