Answer:
Length of char array: sizeof(arr)
Length of a string object: myString.length()
Explanation:
The sizeof approach is generally not recommended, since this information is lost as soon as you pass the array to a function, because then it becomes a pointer to the first element.
Answer: D) components are instances of abstraction
Explanation:
As, implicit invocation is the process by which it is used by the the software designer for styling the architecture of the software,where the event handling structured are formed in the system. The main aim of the implicit invocation is to separated the conceptual concern for maintaining or improving the ability of the software engineer. It is basically based on the notion of the broadcasting and based on the event driven. The components are the instance of the abstraction which are not used as the components in implicit invocation which are relinquished control the system over the computational performance,this is the major disadvantage of the implicit invocation.

Answer:
c. Math.pow(-2.0,15.0) to (Math.pow(2.0,15.0) -1).
Explanation:
short represents a 16-bit signed integer. short is used to save memory because it occupies less space than integers where integers occupy 4 bytes short occupies 2 bytes.
Since it is signed so first bit is used to represent the sign if 0 then positive and 1 then the integer is negative.We are left with 15 bits.
So the range is -2¹⁵ to 2¹⁵-1.
Hence the answer is option c.
Answer:
The operating system must by the use of policies define access to and the use of all computer resources.
Policies are usually defined during the design of the system. These are usually default in settings. Others are defined and or modified during installation of the addon and or third-party software.
Computer Security Policies are used to exact the nature and use of an organisations computers systems. IT Policies are divided into 5 classes namely:
- General Policies
- Server Policies
- VPN Policies
- Back-Up Policies
- Firewall Access and Configuration Policies
