In Cloud9, create a new file called function. cpp. If you aren't sure how to create a new .cpp file in the Cloud9 environment, refer Slide 24 of the Cloud9SetUpSlides (Links to an external site.). In this new file write a function called swapInts that swaps (interchanges) the values of two integers that it is given access to via pointer parameters. Write a main function that asks the user for two integer values, stores them in variables num1 and num2, calls the swap function to swap the values of num1

#include <iostream>  

using namespace std;  

void swapInts(int* x, int* y) {

*x = *x + *y;

*y= *x - *y;

*x = *x - *y;  

}

int main(){    

int num1, num2;

cout << "Before swap:";

cin>>num1;  cin>>num2;

swapInts(&num1, &num2);  

cout<<"After swap:"<<num1<<" "<<num2;

}      

Explanation:

The function begins here:

This line defines the function

void swapInts(int* x, int* y) {

The next three line swap the integer values

*x = *x + *y;

*y= *x - *y;

*x = *x - *y;  

}

The main begins here:

int main(){  

This line declares two integer variables

int num1, num2;

This line prompts the user for inputs before swap

cout << "Before swap:";

This line gets user inputs for both integers

cin>>num1;  cin>>num2;

This line calls the function

swapInts(&num1, &num2);  

This prints the numbers after swap

cout<<"After swap:"<<num1<<" "<<num2;

}

i would first let him be aware that a cover letter is official and confidential and it requires a proper formatting so that the employer doesn't have hard time when going through it. he should write it in paragraphs of about two to four sentences and use proper grammar a , spelling and proper punctuation. i will also advice him not to be emotional and not also to use images.then base his attention to the details of the job described and not other things. that is he be specific to the responsibilities and to the employers requirements. on this he should make sure that the letter reflects how good he is for the requirements detailed by the employer

the letter should not be too long nor too short.
