When an object of a derived class is instantiated, the base class constructor initializes the base class members.

<h3>What is the meaning of basic class?</h3>

A base class is a course, in object-oriented programming terminology, from which other classes are derived.
It allows the design of other types that can reuse the code implicitly inherited from the base class (except constructors and Destructo
A class that is a parent of another class, or from which other classes can be derived, is understood as a base type.

SOVA2 [1]

Answer:

Effective guards

Explanation:

Risks appear when parts of the machine move or have the potential to move. The movements can be rotation, displacement, transverse or alternative (eg from top to bottom or from back to front).

Basic types of guards or effective protections on machines. There are in many ways, including:

- Guards, physical barriers designed as part of the machine, or added to the machine, for example envelopes (fixed or mobile), covers, shields, etc;

- Presence Detection devices, do not prevent access but stop the movement of dangerous parts before contact with them is achieved, for example light curtains, area scanners and pressure mats;

- Protection devices, do not prevent access or stop the machine but allow safer operation. For example, "dead man" or "double keypad" devices;

- Alarms and Warnings, warn staff about the dangers. They can be permanent (eg warning signs) or activated when hazards appear;

- Emergency stops, do not prevent access to dangerous parts or risk, but if activated during an emergency, they can avoid incidents or reduce them significantly.

Before selecting the type of guard, a machine risk assessment must be carried out.

What validation type would you use to check that numbers fell within a certain range? a) range check b)presence check c)check di

olga2289 [7]

Answer:

a) range check

Explanation:

Validation can be defined as an automatic computer check that is designed to ensure any data entered is sensible, consistent, feasible and reasonable.

Basically, there are five (5) main validation methods and these includes;

I. Presence check: checks that the user enters (inputs) data into the field. It ensures a field isn't accidentally left blank.

II. Length check: checks that the data entered isn't too short or too long. It ensures that the data meets the minimum characters.

III. Type check: checks that the data entered is in the right format. For example, string, integer, float, etc.

IV. Check digit: checks that the digit entered is acceptable and consistent with the rest of the digits.

V. Range check: checks that the data entered is between the accepted lower (minimum) and upper (maximum) level.

Hence, range check is a validation type you would use to check that numbers fell within a certain range.

For example, 0 < x > 1000 is a range check.
