hamyarragma : I'd like to better understand how all this works. In the United States at least, Visa and MasterCard branded debit cards look like any visa/mastercard but have the word DEBIT clearly displayed on the front. From my understanding, they will work where at any merchant who accepts Visa or MasterCard electronically, (not those who make imprints of the card though?), and will be processed by Visa and MasterCard the same way as a credit card with one of those brands (you often have to sign for your purchase). I assume they can be used abroad in this fashion too. There is also the PIN point of sale type of transaction, where the interchange fees are lower. Some merchants (e.g. Costco) only accept cards this way. Are these transactions processed by VISA and MasterCard, or some other way (PLUS, Cirrus, or ACH?) Furthermore, can these cards be used abroad for PIN POS transactions (other than at ATMs)? In addition, will Visa or Mastercard debit cards issued abroad work in the United States at merchants for PIN-based purchases, or must they then be processed as credit cards by the merchants? I know in many countries (chiefly Europe) MasterCard operates a separate network, Maestro, where cards are accepted through Cirrus ATMs worldwide in addition to merchants who accept Maestro, but not at merchants who accept only MasterCard and not Maestro specifically. Visa has something similar (I think it's called Visa Electron)

But am I correct to say Maestro terminals will not accept non-Maestro Cirrus network cards, and MasterCard debit accepting terminals (with PIN POS capability) will not accept Cirrus cards that do not display "MasterCard" and "DEBIT" on them?

Do Visa and MasterCard issue any other types of Debit cards, other than the ones mentioned above?

I'm curious about this.

Spummakem : I have old windows7 pc and trying to buy new one. I don't know if it is possible to transfer all the application software's such as Microsoft office, Photoshop, expression web, etc. all those licensed programs which needs product key or serial number to download in PC. If it is possible, how can I transfer them all?

brlad1ley : Hello

It's not possible to make a transfer. You need to install the software on your new pc.

Nenrycesy : You need to use the original installer. Most Adobe products have a way for you to deauthorize them and release the key for use on another machine. If you can't find this, contact Adobe's customer service.

GradGuirer : This is the last question in my programming homework (and I am very lost):

• The following algorithm may be used to determine the number of bits that are used to represent
an unsigned int:
1. Starting with an unsigned int initialized to 1, keep multipying it by 2 until it equals 0.
2. The number of times you multiply it by 2 is related to the number of bits used to represent
the unsigned int’s.
• Write a function that determines the number of bits that are used to represent an unsigned int
on the computer that executes the program.
• Your function has to be compatible with the following main routine.

#include <iostream>
using namespace std;
//Function definition goes here
int main(void)
{ cout << "The unsigned int size is " << intSize()
<< " bits on this computer\n";
return 0;

Any tips would be helpful! Thanks!

Jennitin79 : And what exactly are you lost on?

You're given the exact algorithm on how to do it, and you're even given the start and end of the program. You just have to write the middle.

HireeLarp : Here you go. The steps in your problem spell out what to do. I've translated them to C/C++ for you below. (compiled and ran too )

unsigned int i=1; /* start with an unsigned int init'd to 1*/
int count=0;

while (i != 0) { /* while it does not equal 0 */
count++; /* number of times you multiply by 2 is number of bits */
i = i*2; /* keep multiplying it by 2 */
return(count); /* return number of bits */

Chidaimampham : here is the easy way...

unsigned intSize(){
return CHAR_BIT* (sizeof (unsigned));

another way is:

unsigned j=1;
j<<=1;// just count how many times you have to shift j left to get to 0

Obseshach : Using functional decomposition, design and write a C++ program that inputs a series of 24 hourly temperatures
from a file, and you will create your own input data file with necessary data for your test cases. You will output
a bar chart (using stars) of the temperatures for the day. The temperature should be printed to the left of the
corresponding bar, and there should be a heading that gives the scale of the chart. The range of temperatures
should be from –30 to 120. Because it is hard to display 150 characters on the screen, you should have each star
represent a range of 3 degrees. That way, the bars will be at most 50 characters wide. Here is a partial
example, showing the heading, the output for a negative temperature, and the output for various positive
temperatures. Note how the temperatures are rounded to the appropriate of stars.
Temperatures for 24 hours:
-10 0 10 20 30
-20 *******?
0 ?
2 ?*
5 ?**
10 ?***
20 ?*******
30 ?**********
[ Notes ]
1) While the program specified 24 input temperatures, your program should work regardless of
how many data in the input file.
2) You will need to write the output to the screen and also to an output file.

This what i have so far

#include <iostream>
#include <cmath>
#include <string>
#include <iomanip>
#include <fstream>
using namespace std;

int main(){
ifstream inFile;
int temp;
int i;

cout <<"Temperatures for 24 hours"<<endl<<endl;
for(int i= -10; i<30;i+=10){
//cout<<" ";Erase this
cout<<" ";


cout << endl;// This make a new line. Comment it out too see what happens
// When you comment it out, your stuff is posted right after the 10 ("C:\\Dev-Cpp\\sources.txt");
if (!inFile) {
cout << "Unable to open file";
return 13;
// terminate with error

while(inFile >> temp){

while(temp <-30 || temp >120);

//once we have the temperature between -30 to 120 range, we need to do some logic to draw the stars and bar
//look at example at see how they explained it

if (temp ==0 || temp ==1 || temp==2){
cout<< "|"<<endl;

else if (temp >=3){
//for the numbers from 3 to 120
//NUMBER OF STAR = floor((temp+1)/3)
int number_of_star =floor(static_cast<float>((temp+1)/3));
string print="|";
for(int i =0; i < number_of_star; i++){


else if(temp <=-1){
//for the number from -30 to -1
//NUMBER OF STAR = ceil((temp-2)/3))

float x = (temp-2)/3;
int number_of_star = ceil(x);
number_of_star *=-1;

string print="";
for(int i=0; i < number_of_star; i++){
print +="|";

igorisbar : " functional decomposition" means what it says - you need to work out the components of the overall task and write them as functions. You shouldn't have a line of code until you've designed the whole task.
