Write the definition of a function named swapints that is passed two int variables. the function returns nothing but exchanges the values of the two variables. so, if j and k have (respectively) the values 15 and 23, and the invocation swapints(j, k) is made, then upon return, the values of j and k will be 23 and 15 respectively.

Following are the program in the C++ Programming Language.

#include <iostream>

//header file

using namespace std;

//using namespace

void swapints(int &j, int &k){

//definition of the function

int temp;

temp = j;

j = k;

k = temp;

}

// function declaration

void swapints(int &j, int &k);

int main() {

// local variable declaration:

int j = 15;

int k = 23;

std::cout << "Before the swapping, value of j : "<<j<<endl;

std::cout << "Before the swapping, value of k : "<<k<<endl;

/* calling a function to swap the values using variable reference.*/

swapints(j, k);

std::cout << "After the swapping, value of j : "<<j<< endl;

std::cout << "After the swapping, value of k : "<<k<< endl;

return 0;

}

Output:

Before the swapping, value of j : 15

Before the swapping, value of k : 23

After the swapping, value of j : 23

After the swapping, value of k : 15

Explanation:

Here, we define the header fine and namespace <iostream> and "std".

Then, we define a function named "swapints()" and pass two reference variables in parameter.

Then, inside the function, we perform the codes of swapping.

Then, we define the main() function inside it we define two integer variable "j" and "k" assign value "j" to 15 and "k" to 23 and print both the variables.

Then, inside main() function we call the function "swapints()" and pass value to its parameters.

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
