Explanation:
The statement is true. In object-oriented programming, an abstract class is a class that cannot be instantiated on its own and can only serve as a base for other classes. Subclasses of an abstract class must provide definitions (implementations) for all the abstract methods declared in the superclass. Failure to do so will result in a compilation error. Therefore, to instantiate a subclass of an abstract class, all the abstract methods must be implemented in the subclass.

Explanation:
The fourth-stroke engine cycle is a kind of motor that performs four distinct thrusts while rotating a rotor. The first is the inlet, where the piston starts at the top did centre. The second stage is compression, which begins at bottom dead centre and involves the engine compressing the mixture with air in preparation for ignition. The third stage is ignition, which initiates the cycle's second revolution. Finally, the pistons return to The top dead center from Bottom did center during the exhaust.
Answer: 1. Urgent assistance needed 2. Immediate help required 3. Urgent request for help 4. Please help immediately The option "Urgent assistance needed" is the most direct and explicit in conveying the urgency of the situation, making it the most suitable for urgent requests. The option "Immediate help required" also conveys a strong sense of urgency, although it is slightly less direct than the first option. The option "Urgent request for help" clearly indicates the need for urgent assistance, but it may be perceived as slightly less urgent compared to the first two options. The option "Please help immediately" is still urgent but may be considered slightly less urgent or forceful than the other options, as it includes a polite request along with the sense of urgency. Ultimately, the choice of which composition to use depends on the specific context and the desired tone of the request for help.

b. If the end of file is encountered, 0 is returned.
Explanation:
A read function is one of the functions used in computer programming. A read function is used to read an information or data that was written before into a file.
If any portion of a regular file before to the end of file has not been written and the end of file is encountered the read function will return the bytes with value 0.
If read function has read some data successfully, it returns the number of bytes it read.
