Create a class Car, which contains Three data members i.e. carName (of string type), ignition (of bool type), and currentSpeed (

of integer type)
 A no-argument constructor to initialize all data members with default values
 A parameterized constructor to initialize all data members with user-defined values
 Three setter functions to set values for all data members individually
 Three getter function to get value of all data members individually
 A member function setSpeed( ) // takes integer argument for setting speed
Derive a class named Convertible that contains
 A data member top (of Boolean type)
 A no-argument constructor to assign default value as “false” to top
 A four argument constructor to assign values to all data-members i.e. carName, ignition, currentSpeed and top.
 A setter to set the top data member up
 A function named show() that displays all data member values of invoking object
Write a main() function that instantiates objects of Convertible class and test the functionality of all its member functions.

Answer:

Copy paste it.

Explanation:

#include <iostream>

#include <string>

using namespace std;

//Create a class Car, which contains • Three data members i.e. carName (of string type), ignition (of bool type), and //currentSpeed (of integer type)

class Car

{

public:

string carName;

bool ignition;

int currentSpeed;

//A no-argument constructor to initialize all data members with default values

//default value of string is "",bool is false,int is 0

Car()

{

carName="";

ignition=false;

currentSpeed=0;

}

//A parameterized constructor to initialize all data members with user-defined values

Car(string name,bool i,int speed)

{

carName=name;

ignition=i;

currentSpeed=speed;

}

//Three setter functions to set values for all data members individually

// Three getter function to get value of all data members individually

void setCarName(string s)

{

carName=s;

}

void setIgnition(bool ig)

{

ignition=ig;

}

void setCurrentSpeed(int speed)

{

currentSpeed=speed;

}

string getCarName()

{

return carName;

}

bool getIgnition()

{

return ignition;

}

int getCurrentSpeed()

{

return currentSpeed;

}

//A member function setSpeed( ) // takes integer argument for setting speed

void setSpeed(int sp1)

{

currentSpeed=sp1;

}

};

//Derive a class named Convertible

class Convertible:public Car

{

//A data member top (of Boolean type)

public:

bool top;

public:

//A no-argument constructor to assign default value as “false” to top

Convertible()

{

top=false;

}

//A four argument constructor to assign values to all data-members i.e. carName, ignition,

//currentSpeed and top.

Convertible(string n,bool i,int s,bool t):Car(n,i,s)

{

carName=n;

ignition=i;

currentSpeed=s;

top=t;

}

// A setter to set the top data member up

void setTop(bool t)

{

top=t;

}

//A function named show() that displays all data member values of invoking object

void show()

{

cout<<"Car name is:"<<carName<<endl;

cout<<"Ignition is: "<<ignition<<endl;

cout<<"Current Speed is :"<<currentSpeed<<endl;

cout<<"Top is:"<<top<<endl;

}

};

//main function

int main()

{

//creating object for Convertible class

Convertible c1("Audi",true,100,true);

c1.show();

c1.setCarName("Benz");

c1.setIgnition(true);

c1.setCurrentSpeed(80);

c1.setTop(true);

c1.show();

cout<<"Car Name is: "<<c1.getCarName()<<endl;

cout<<"Ignition is:"<<c1.getIgnition()<<endl;

cout<<"Current Speed is:"<<c1.getCurrentSpeed()<<endl;

return 0;

}

Answer:

An observation: Java does not support true multi-dimensional arrays; rather, it supports 1-dimensional arrays, where each element can itself be another 1-dimensional array. The difference is the way memory is allocated, where a[i][j] differs from a[i,j].

Suppose you have two arrays of ints, arr1 and arr2, each containing ints that are sorted in ascending order. Write a static meth
telo118 [61]
Since both arrays are already sorted, that means that the first int of one of the arrays will be smaller than all the ints that come after it in the same array. We also know that if the first int of arr1 is smaller than the first int of arr2, then by the same logic, the first int of arr1 is smaller than all the ints in arr2 since arr2 is also sorted.

public static int[] merge(int[] arr1, int[] arr2) {
int i = 0; //current index of arr1
int j = 0; //current index of arr2
int[] result = new int[arr1.length+arr2.length]
while(i < arr1.length && j < arr2.length) {
result[i+j] = Math.min(arr1[i], arr2[j]);
if(arr1[i] < arr2[j]) {
i++;
} else {
j++;
}
}
boolean isArr1 = i+1 < arr1.length;
for(int index = isArr1 ? i : j; index < isArr1 ? arr1.length : arr2.length; index++) {
result[i+j+index] = isArr1 ? arr1[index] : arr2[index]
}
return result;
}


So this implementation is kind of confusing, but it's the first way I thought to do it so I ran with it. There is probably an easier way, but that's the beauty of programming.

A quick explanation:

We first loop through the arrays comparing the first elements of each array, adding whichever is the smallest to the result array. Each time we do so, we increment the index value (i or j) for the array that had the smaller number. Now the next time we are comparing the NEXT element in that array to the PREVIOUS element of the other array. We do this until we reach the end of either arr1 or arr2 so that we don't get an out of bounds exception.

The second step in our method is to tack on the remaining integers to the resulting array. We need to do this because when we reach the end of one array, there will still be at least one more integer in the other array. The boolean isArr1 is telling us whether arr1 is the array with leftovers. If so, we loop through the remaining indices of arr1 and add them to the result. Otherwise, we do the same for arr2. All of this is done using ternary operations to determine which array to use, but if we wanted to we could split the code into two for loops using an if statement.
