Question

This is code for c++. Any help would be great.

#include <iostream>

using namespace std;

/* 1. Create a method that prints your name

*/

/* 2. Create an overloaded method that takes an integer and prints it out

multiplied

* by itself

* Print out the argument inside the method and then call the method from main

* and print it out

* What was the typed of passing used inhere ?

*/

/* 3. Create an overloaded method that takes a double and returns it as an integer

* Call the method from main , reassign the passed in argument to the return value

* What was the typed of passing used inhere ?

*/

/* 4. Create an overloaded method that takes an address of an integer

* Pre decrement the argument

* Print it out inside the method and in the main

* What was the type of passing used inhere ?

*/

/* 5. Create a method that takes a double array and the size of the array.

* The method casts elements of the array to an integer

* Print out the result inside the method and outside

* What was the type of passing used for the array?

*/

/* 6. Create an overloaded method that takes a double array and returns it an

integer array

* Remember to use pointer and define your return array to be static

* Print out the returned array in the main method

*/

/* 7. Create a method that takes three doubles whose default values are 2.2 3.3 4.4

* The method returns the additions of the arguments and print the result

* Call the method again and pass in two arguments and print the result

* Call the method again and pass in three arguments and print the result

*/

/* 8. Create an overloaded method of the previous method that takes two integers

* with default values and assign the answer to a global variable called addition

* The method returns the additions of the arguments

* Print out the result inside the main method

*/

int main() {

// Call your methods in the main method and show your work

return 0;

}

Answer 1

Here is the code for the above assignment.

Feel free to comment on any doubts and give thumbs up.

Additionally, I have added comments for your better understanding.

Code :

#include<iostream>

using namespace std;

int addition;

/* 1. Create a method that prints your name

*/

void printName(const char* name){

    cout << "Name : "<< name << "\n";

}

/* 2. Create an overloaded method that takes an integer and prints it out

multiplied

* by itself

* Print out the argument inside the method and then call the method from main

* and print it out

* What was the typed of passing used inhere ?

* Ans : the type of passing used in here is pass by value.

*/

void overloadedMethod(int value){

    cout << "Priting out the argument : " << value << "\n";

    cout << "Printing int value by multiplied by itself: " << value * value << "\n";

}

/* 3. Create an overloaded method that takes a double and returns it as an integer

* Call the method from main , reassign the passed in argument to the return value

* What was the typed of passing used inhere ?

* Ans : the type of passing used in here is pass by value.

*/

int overloadedMethod(double value){

    return (int)value;

}

/* 4. Create an overloaded method that takes an address of an integer

* Pre decrement the argument

* Print it out inside the method and in the main

* What was the type of passing used inhere ?

* Ans: the type of passing used in here is pass by address.

*/

void overloadedMethod(int *address_of_int){

    cout << "Printing the int value after increement it by one : " << ++(*address_of_int) << "\n";

}

/* 5. Create a method that takes a double array and the size of the array.

* The method casts elements of the array to an integer

* Print out the result inside the method and outside

* What was the type of passing used for the array?

* Ans : the type of passing used for the array is pass by reference

*/

void doubleArray(double arr[], int size){

    cout << "Printing double array as an int values: \n";

    for(int i = 0 ; i < size ; ++i){

        arr[i] = (int)arr[i];

        cout << arr[i] << "\n";

    }

}

/* 6. Create an overloaded method that takes a double array and returns it an integer array

* Remember to use pointer and define your return array to be static

* Print out the returned array in the main method

*/

static int* method(double arr[], int size){

    static int* intArr = new int[size];

    for(int i = 0 ; i < size ; ++i){

        intArr[i] = (int)arr[i];

    }

    return intArr;

}

/* 7. Create a method that takes three doubles whose default values are 2.2 3.3 4.4

*/

double method1(double d1 = 2.2, double d2 = 3.3, double d3 = 4.4){

    return d1 + d2 + d3;

}

/* 8. Create an overloaded method of the previous method that takes two integers

* with default values and assign the answer to a global variable called addition

* The method returns the additions of the arguments

* Print out the result inside the main method

*/

int method1(int i1 = 2, int i2 = 3){

    addition = i1 + i2;

    return addition;

}

// main method

int main(){

    // 1. calling print name method to print name;

    printName("Your Name");

    // 2.

    overloadedMethod(5);

    // 3

    int value = overloadedMethod(2.123);

    cout << "Printing value after converting the double number to int : " << value << "\n";

    // 4

    int intNumber = 5;

    overloadedMethod(&intNumber);

    cout << "Value after calling method : " << intNumber << "\n";

    // 5

    const int arraySize = 3;

    double doubleArr[arraySize] = {2.2, 3.45, 4.56};

    cout << "Printing the double array : \n";

    for(int i = 0 ; i < arraySize ; ++i){

        cout << doubleArr[i] << "\n";

    }

    doubleArray(doubleArr , arraySize);

    // 6

    cout << "Printing array after making all elements of array int \n";

    int* arrPointer = method(doubleArr, arraySize);

    for(int i = 0; i < arraySize ; ++i){

        cout << arrPointer[i] << "\n";

    }

    // 7

    cout << "Calling method with two double values : " << method1(5.6, 6.5) << "\n";

    cout << "Calling method with three double values : " << method1(5.3, 5.6, 6.5) << "\n";

    // 8

    cout << "Calling overloaded method with two int arguments : " << method1(2 , 6) << "\n";

    cout << "Value of addition global variable : " << addition << "\n";

}
