long int strtol(const char*nptr,char**endptr,int base);

Analytical : The parameter string nptr the number base (hexadecimal number ) is converted to long int;

   nptr to: 0 X represents 1 . 6 hexadecimal string, 0 (zero ) represents a digit string 8

   endptr: If is N ULL character pointer, will encounter undesirable condition whereby the termination of the return nptr

   Base : the number of decimal used

Example: int n-strtol = ( "0x2D" , NULL , 16 ); // 16 hexadecimal string rotation 1 0 hexadecimal numbers
