Answer:
Option 2 i.e., instance methods is the correct answer to the following question.
Explanation:
Because the instance method or function is the function that needed the class object to be called.
<u>For Example:</u>
//header file
#include <iostream>
using namespace std;
//define class
class Test
{
public:
//instance method
void getins()
{
cout<<"I AM Instance method";
}
};
int main()
{
//creating object
Test obj;
//calling of instance method through class object
obj.getins();
}
<u>Output</u>:
I AM Instance method

Explanation:
Duplicate tuples are not allowed in a relation because the specifications of the constraints of the regional integrity are violated, especially the main constraint that states that there can be no identical values for the attributes of two tuples at any database relation state.
Also, duplicate tuples are not allowed in a relation due to the fact that they lead to redundancy of the data base which in turn, slowing down the speed of the database when data processing such as inserting, querying, updating, deleting, etc are being performed.
Your answer would be
A. The editorial is data.
I just took this test :)
Answer:
The solution code is written in C++
- float cellPhone(int m, int tx){
- float COST_PER_MIN = 0.1;
- float COST_PER_MESSAGE = 0.2;
-
- float bill_amount = m * COST_PER_MIN + tx * COST_PER_MESSAGE;
-
- return bill_amount;
- }
Explanation:
Firstly, declare a function named cellPhone() that takes two input parameters, m and tx (Line 1).
Since the policy of the carrier company is not given in the question, I make a presumption that the cost per minutes is $0.10 and the cost per message is $0.20 (Line 2- 3).
Next, apply the formula m * COST_PER_MIN + tx * COST_PER_MESSAGE to calculate the total bill (Line 5) and return the bill_amount as function output (Line 7).
