SSCANF definition and usage and analysis
The sscanf () function parses input from a string according to the specified format.

If only two parameters are passed to the function, the data is returned as an array. Otherwise, if additional parameters are passed, the parsed data is stored in these parameters. If the number of delimiters is greater than the number of variables that contain them, an error occurs. However, if the delimiter is less than the variable, the extra variable contains null.
