unsigned long long int strtoull( const char * s, char ** endptr, int base )
Converts a string in s to an unsigned long long.
A nonzero base can be supplied to force a specific radix.
endptr can be supplied in order to get a pointer to the remainder of the string.
Returns the value in the string if present, clamped to the maximum on overflow
Returns 0 if the string isn’t a number
