Answer:
False
Database management systems are expected to handle binary, unary and ternary relationships.
Explanation:
Unary Relationship: It is a recursive relationship which includes one entity in a relationship which means that there is a relationship between the instances of the same entity. Primary key and foreign key are both the same here. For example a Person is married to only one Person. In this example there is a one-to-one relationship between the same entity i.e. Person.
Binary Relationships: It is a relationship involving two different entities. These two entities identified using two relations and another relation to show relationship between two entities and this relation holds primary keys of both entities and its own primary key is the combination of primary keys of the both relations of the two entities. For example Many Students can read a Book and many Books can be obtained by a Student.
Ternary Relationships: is a relationship involving three entities and can have three tables. For example a Supplier can supply a specific Part of many Mobiles. Or many Suppliers may supply several Parts of many Mobile models.
Answer:
#include <iostream>
using namespace std;
void miles_to_km(float &miles)//function to convert miles to kilo meters.
{
miles=miles*1.6;
}
int main() {
float miles;
cout<<"Enter the miles"<<endl;
cin>>miles;//taking input of the miles..
miles_to_km(miles);//calling function that converts miles to km..
cout<<"The number of km is "<<miles<<endl;//printing the km.
return 0;
}
Output:-
Enter the miles
54
The number of km is 86.4
Explanation:
I have created a function miles_to_km of type void which has the argument miles passed by reference.In the function the variable miles is converted to kilo meters.Then in the main function the function is called with the value prompted from the user.Then printing the changed value.
Answer:
- public class Square {
- public static boolean isPerfectSquare(int n){
- int sqrt_n = (int) Math.sqrt(n);
- if(sqrt_n * sqrt_n == n ){
- return true;
- }else{
- return false;
- }
- }
- }
Explanation:
Firstly, use sqrt method from Math package to calculate the square root of input n (Line 3). Cast the result to integer and assign it to sqrt_n variable.
Next, square the sqrt_n and check if it is equal to input n (Line 4). If so, return true, if not, return false (Line 4-8).
I believe your answer would be:
1: Open the command prompt window. Do this by clicking the "Start" button, and then selecting "Run." In the window that appears, type "cmd" into the text box and click the "OK" button.
2: Release the computer's current IP address. To do this, type "ipconfig /release" into the command prompt window and press Enter.
3: Acquire a new IP address. Do this by typing "ipconfig /renew" into the command prompt window and pressing Enter. This should assign the computer a new IP address, which will be different from the previous address.
4: Cycle your modem's power. If the above steps don't work, you can try renewing your IP address by cycling your modem's power. Turn off both your computer and your modem (and your router, if you have one). Wait at least 5 minutes, then turn everything back on. If your computer is set to receive an IP address dynamically (the most likely configuration), you should be assigned a new IP address automatically.
5: Check to make sure your IP address has changed. To do this, you can log on to a number of different websites that tell you your IP address.
Hope I helped, if so may I get brainliest and a thanks?
Thank you, Have a good day! =)
Answer:
Following are the calling of the given question
public static void main(String[] args) // main function
{
int store; // variable declaration
store = sum(32,15,"san"); // Calling of sum()
System.out.println(" TheValue returned by sum() : "+store); // display
}
Explanation:
Following are the description of the above statement
- Here is the name of function is sum() In the sum() function definition there are 3 parameter in there signature i.e two "int" type and 1 is "string" type .
- In the main function we declared the variable store i,e is used for storing the result of sum() it means it storing the result of value that is returning from the definition of sum() function .
- After that calling the function by there name and passing three parameter under it sum(32,15,"san"); and store in the "store" variable.
- Finally print the value by using system.out.println ().
