Detailed description of strtol Functions

Long int strtol (const char * nptr, char ** endptr, int base );
This function converts the nptr parameter to the Growth integer number based on the base parameter.
The base parameter ranges from 2 to 36, or 0. The base parameter indicates the base mode,
For example, if the base value is 10, the base value is 10, and if the base value is 16, the base value is 16.
When the base value is 0, 10 is used for conversion.
The character is converted in hexadecimal notation, And the '0' prefix is not '0x'
8-in conversion will be used. At the beginning, strtol () will scan the nptr parameter.
Character string, skip the leading space character until it meets a number or positive or negative sign
Start conversion, and end conversion when a non-number or string ends ('\ 0,
And return the result. If the endptr parameter is not NULL
The character pointer in the terminated nptr is returned by the endptr.
