Answer:
They are both ways to identify assets (e.g., persons, animals, objects).
Explanation:
A barcode is a bit of information (usually a number) printed as a line or block pattern on a surface (e.g., a sticker).
An RFID is a bit of computer memory with an antenna.
Both can be read with the appropriate scanner device.
Answer:
a) Global
Explanation:
The scope of a variable declared outside of any function is Global.
Let us consider an example:
int g;
int add(int a,int b){
return a+b;
}
int subtract(int a,int b){
return a-b;
}
Here the variable g is defined outside any function and is accessible anywhere within the program. This is a global variable.
Variables defined within each function - a,b on the other hand have a local scope are are visible only within their respective function bodies.
Answer:
Yes, overloading is one of the methods which are popular in programming language. Overloading basically refers to the same function but different signature called function overloading or method overloading. It is the ability to define the multiples method by using the single identifier.
The overloading is important because it has the ability to design the multiple method by using similar name. It also provide the high flexibility to the programmers to call the same method in the data. overloading basically provide the high clarity in the code.
Overloading is used to achieved the compile time polymorphism.
Following are program of function overloading in c++ are:
Class abc // creating class
{
public:
int p;
void fun() // function fun with no parameter/
{
cout<<” hello “;
}
void fun(int a) // function fun with parameter
{
p=a;
cout<<p;
}
};
int main() // main function
{
abc ob; // creating object
ob.fun();// print hello;
ob.fun(6);// print 6
return 0;
}
Explanation:
In this program the function fun() have same name but different signature in the main method we create the object of class abc i.e ob. ob.fun() this statement called the function with no parameter and ob.fun(6) this statement will called the function with integer parameter.
Answer:
By presuming the question expect us to write a program to address the problem and the solution code written in Python is as follow:
- beer_name = input("Enter beer name: ")
- abv = int(input("Enter ABV value: "))
-
- if(abv > 10):
- label = "Very High"
- elif(abv >=6):
- label = "High"
- elif(abv >=3):
- label = "Average"
- else:
- label = "Low"
-
- print("Beer Name: " + beer_name)
- print("ABV value: " + str(abv))
- print(label)
Explanation:
Firstly, we can use input function to prompt user to input beer name and ABV value (Line 1 - 2).
Next, create if else if statements to check abv fallen into which range of value and then set a label accordingly (Line 4 -11). For example if abv is 4, the label will be set to "Average".
At last, print the information of beer that includes beer name, abv value and label (Line 13 - 15).
