Answer: Naming the function
Explanation:
The first item for defining the function is the naming of the function. In the function, the first line is known as header and rest of the function is known as body of the function.
The function name is the first step while defining the proper function as we can define the actual function name on which the program are rest based.
We can define a function from which the each value from the set of the components are basically associated with the second component in that particular function.
I believe you can blur the background of the image you are taking of.
Answer:
Phishing.
Explanation:
Networks and computer systems in a network are susceptible to cyber attacks. A cyber attack is a networking term that describes a situation where a network is penetrated by a malicious process or program induced by an attacker or attackers.
A cyber attacker's sole intention is to steal information needed to achieve a malicious and devastating action to a client's personal assets. An example of such attacks is phishing.
Phishing is an attack that collects client's personal information at an imposter website after receiving an email from a person masquerading as an employee from a bank.
Signal processing deals with the analysis and operation of a. mechanical signals b. electrical signals c. biological signals. These can be b. digital c. analog which vary across a range of values or b. digital with only two possible values.
Explanation:
- In signal processing, a signal is a function that conveys information about a phenomenon. In electronics and telecommunications, it refers to any time varying voltage, current or electromagnetic wave that carries information.
- A signal may also be defined as an observable change in a quality such as quantity...
- A signal can be audio, video, speech, image, sonar and radar-related
- Signal processing deals with the analysis and operation of mechanical signals, electrical signals and biological signals.
- The value of the signal is an electric potential which is voltage is also a signal.
- The term analog signal usually refers to electrical signals. Analog signals may also be other mediums such as mechanical, pneumatic or hydraulic.
- An analog signal signifies a continuous signal that keeps changes with a time period. A digital signal signifies a discrete signal that carries binary data and has discrete values. Analog signals are continuous sine waves. Digital signal is square waves
Answer:
public class Calculator {
public double add(int a, int b){
return a+b;
}
public double substract(int a, int b){
return a-b;
}
public double multiply(int a, int b){
return a*b;
}
public double divide(int a, int b){
if(b>0){
return a/b;
}
else{
System.out.println("Cannot divide by zero");
}
return -1;
}
}
Explanation:
- Using Java Programming Language, the class Calculator is created. There are no fields (Instance variables) and no constructors since these are not required by the question.
- Four methods (functions) are created: add, substract, multiply and divide as specified in the question.
- Note the use of the if statement in the divide() to handle case of illegal division (by 0)
