+The **`scanf()`** (scan formatted string) function reads a user input and then converts that input into a value that it assigns to a variable.
 
 ## Syntax
 
 ```pseudo
-scanf(string, &variable, &variable2, ... &variableN)
+scanf(string, &variable, &variable2, ..., &variableN)
 ```
 
 The `scanf()` function takes a format specifier string as input, along with a variable for each format specifier in the string. The format specifier string acts as a template that the function will use to convert the user input into values for the variables.
 
-For a short list of format specifiers you can use in the input string, see the 'Format Specifiers' table in the [printf()](../printf/printf.md) documentation.

 > **Note:** `scanf()` does not have any intrinsic validation of the user input. This can cause errors if the user input does not match the format specifiers in the string.
 
 ## Examples
 
+In the following example, the format specifier `%d` tells the function to expect an integer, then assigns it to the variable `yourNumber`:
