When authenticating a user's password, the password supplied by the user is authenticated by comparing the ____ of the password
Bas_tet [7]

Answer:

Hash.

Explanation:

An authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification. Smart cards, digital certificates, picture passwords, and biometrics are generally used to perform an authentication in the field of computer.

Hence, when authenticating a user's password, the password supplied by the user is authenticated by comparing the hash of the password with the one stored on the system.

In Computer science, a hash function can be defined as any function which is used to map data by accepting a block of data with variable length size or arbitrary size as input to produce a fixed size hash values or codes.

Generally, when a block of data (input) of arbitrary size is hashed, the resulting hash values or codes is usually smaller than the input data. Thus, hash functions are considered to be a compression of data and as a result, sometimes called compression functions. Basically, the block size of a hash function typically ranges from 128 bits to 512 bits.

When creating a multi-dimensional array dynamically in C/C++ the Memory Manager will go to great pains to make sure the array is
yuradex [85]

Answer:

Here the statement is false.  

Explanation:

In C/C++, we can define multidimensional arrays in simple words as an array of arrays. Data in multidimensional arrays are stored in tabular form (in row-major order).  

General form of declaring N-dimensional arrays:  

data_type  array_name[size1][size2]....[sizeN];  

data_type: Type of data to be stored in the array.  

          Here data_type is valid C/C++ data type

array_name: Name of the array

size1, size2,... ,sizeN: Sizes of the dimensions.

Foe example:

Two dimensional array:

int two_d[10][20];  

Three dimensional array:

int three_d[10][20][30];

Write the class RoadSegmet. The class inherits from Transportation Class. The Class have a vector hourlySpeeds data field which
OLEGan [10]

Answer:

The length of time on the road segment is calculated by taking it's distance and dividing by the speed at the time of departure. This length of time is then added to the departureTime parameter to get the arrivalTime.

Define a RiverSegment class that inherits from the base TransportationClass from above. This class will have a vector<double> scheduledDepartureTimes data field that will keep track of the departure time (e.g. 10.5 represents the time 10:30) of all ferries on the river. You can assume these are sorted. Additionally, there is a _speed value that is the speed of the ferry at all times (ferries tend to be consistently slow). There is a setSpeed function to change the _speed value. Additionally, there is an addDepartureTime(double hour) function to add a departure time to the vector. Make sure the time are sorted

Computing the arrival time for the RiverSegment is a little more complicated since you need to wait for the next available departure time. Once you find the next available departure time (after the departure time passed in), you need to add the length of time on the river segment. This is done by dividing the _distance by the _speed. Add the time on the river to the departure time (from the vector of departure times) and this will give you the arrive time.

note: If there is no departure time scheduled for after your planned departure, you need to take the first available departure the following day. Our solution assumes the departure times are the same every day.

TransportationLink.h

#include <string>

using namespace std;

#ifndef __TRANSPORTATIONLINK_H__

#define __TRANSPORTATIONLINK_H__

const int HOURS_PER_DAY = 24;

const int MINS_PER_HOUR = 60;

const int MINS_PER_DAY = MINS_PER_HOUR * HOURS_PER_DAY; //24 * 60

class TransportationLink {

protected:

string _name;

double _distance;

public:

TransportationLink(const string &, double);

const string & getName() const;

double getDistance() const;

void setDistance(double);

// Passes in the departure time (as minute) and returns arrival time (as minute)

// For example:

// 8 am will be passed in as 480 (8 * 60)

// 2:30 pm will be passed in as 870 (14.5 * 60)

virtual unsigned computeArrivalTime(unsigned minute) const = 0;

};
