Answer:
Application Programming Interface.
Explanation:
Application Programming Interface(API) is a collection of function, routines, procedures and the protocol which are used create a software application.The main role of API is that it defined or specified how the components of software will interact.
The objective of the Application Programming Interface that it the manufacturer or develop software that is running on system or device. The advantage of using the Application Programming Interface is that we can develop a better program in a very manner by using the API.

Explanation:
Hacking is simply gaining access into a computer through weaknesses that were found in the network system.
We have mainly 5 stages In ethical hacking which although must not be followed sequentially but could produce greater results if it was followed.
These stages includes
1. Reconnaissance
2. Scanning
3. Gaining access
4. Maintaining access
5. Covering tracks.
Answer:
The answer is "option B".
Explanation:
An OTB stands for an over-target baseline, it is a new management benchmark when an original target can't have coincided and new goals for management purposes are required.
- It is also known as a reference to the foundation for calculating or constructing.
- It is an understanding between the client and the contractor that the cost base, which is not part of the original contract budget, should include an extra budget
Answer:
Following are the code to method calling
backwardsAlphabet(startingLetter); //calling method backwardsAlphabet
Output:
please find the attachment.
Explanation:
Working of program:
- In the given java code, a class "RecursiveCalls" is declared, inside the class, a method that is "backwardsAlphabet" is defined, this method accepts a char parameter that is "currLetter".
- In this method a conditional statement is used, if the block it will check input parameter value is 'a', then it will print value, otherwise, it will go to else section in this block it will use the recursive function that prints it's before value.
- In the main method, first, we create the scanner class object then defined a char variable "startingLetter", in this we input from the user and pass its value into the method that is "backwardsAlphabet".
Answer:
The following are the code in the C++ Programming Language.
//define header file
#include <iostream>
// using namespace
using namespace std;
//define a class
class Accumulator
{
//set private access modifier
private:
//declare integer type variable
int sum;
//set public access modifier
public:
//define constructor
Accumulator (int sum)
{
//refer the same class as instance variable
this->sum = sum;
}
//define integer type function
int getSum()
{
//return the value of sum
return sum;
}
//define void type function
void add (int value)
{
//variable sum is increased by the argument value
sum += value;
}
};
Explanation:
<u>The following are the description of the code</u>.
- Firstly, set the required header file and namespace then, define a class 'Accumulator' and inside the class.
- Set private access modifier then, declare an integer data type variable 'sum'.
- Declare a class constructor whose name is the same as the class name 'Accumulator()' and pass integer data type argument 'sum' in its parameter that refers to the same class as instance variable.
- Define a integer data type function 'getSum()' that return the value of the variable sum.
- Finally, define a void type function 'add()' and pass the integer data type argument 'value' in its parameter in which the variable sum is increased by the argument value
.
