Explanation:
Programmers are professional who build computer softwares.
Creating a lookup relationship to indicate that a person has an employer is the data model used to track the data of a developer creating an enhancement to an application that will allow people to be related to their employer. This data model allows for 25people per object.
Answer:
// C++ program to demonstrate inheritance
#include <iostream>
using namespace std;
// base class
class Animal {
public:
void eat() {
cout << "I can eat!" << endl;
}
void sleep() {
cout << "I can sleep!" << endl;
}
};
// derived class
class Dog : public Animal {
public:
void bark() {
cout << "I can bark! Woof woof!!" << endl;
}
};
int main() {
// Create object of the Dog class
Dog dog1;
// Calling members of the base class
dog1.eat();
dog1.sleep();
// Calling member of the derived class
dog1.bark();
return 0;
}
Answer:
- import java.util.Scanner;
- public class Main {
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
- System.out.print("Please enter two characters: ");
- String inputStr = input.nextLine();
-
- if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
- System.out.println("Biology");
- }
- else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
- System.out.println("Computer Science");
- }
- else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
- {
- System.out.println("Information Technology and Systems");
- }
- else{
- System.out.println("Invalid major");
- }
-
- int num = Character.getNumericValue(inputStr.charAt(1));
-
- if(num >= 1 && num <= 4){
- switch (num){
- case 1:
- System.out.println("freshman");
- break;
- case 2:
- System.out.println("sophomore");
- break;
- case 3:
- System.out.println("junior");
- break;
- case 4:
- System.out.println("senior");
- break;
- }
-
- }
- else{
- System.out.println("Invalid year status");
- }
-
- }
-
- }
Explanation:
The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.
The part 2 is to validate the year status to make sure it only fall within the range of 1-4 (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.
