Which of the following is NOT a useful strategy when making an informed purchase ?

Answer:

3 Reasons to Use Cash and 3 Reasons to Choose Credit

Credit and debit cards have become so ubiquitous, you'd be forgiven for thinking physical cash is just a couple years away from being declared obsolete and worthless by the government.

Well, as it turns out, the death of dead presidents is greatly exaggerated, as over $1.25 trillion still circulates around the United States alone.

Way too many people use cash for it to ever go away completely, regardless of how much plastic gets wiped every day.

Easier to Watch and Control Your Spending

Actually seeing the cash you owe, as opposed to simply staring at a generic card with no monetary value of its own, can remind you to spend less overall, since all of a sudden the money is real, and real valuable at that.

Financial guru Ramit Sethi, for example, lost his credit card, and spent nothing but cash until a replacement came. He reported spending 18% less when forced to watch his green wad dwindle in real-time.

Some Places Still Don't Take Plastic (or Require a Minimum Purchase Amount)

Amazingly, over half of all small businesses won't take cards, likely because they can't afford the fees.

It's always good to keep at least some cash on you in case you need to make a purchase from one of these places.

Explanation:

3 Reasons To Use Cash (and 3 Reasons To Choose Credit)

Credit and debit cards have become so ubiquitous, you'd be forgiven for thinking physical cash is just a couple years away from being declared obsolete and worthless by the government.

Well, as it turns out, the death of dead presidents is greatly exaggerated, as over $1.25 trillion still circulates around the United States alone.

Way too many people use cash for it to ever go away completely, regardless of how much plastic gets wiped every day.

So why in the world would anydiv still pay with Georges and Bens? Here are a few good reasons why:

Less Chance of Identity Theft

Few things are scarier than hearing that the store you regularly swipe your card at just had a security breach, and that some anonymous criminal may have your identity at their disposal.

Paying cash eliminates that issue -- chunks of metal and pieces of paper stacked in a register tells fraudsters absolutely nothing, while the information sent to vulnerable computers via your bank card can reveal everything.

Easier to Watch and Control Your Spending

Actually seeing the cash you owe, as opposed to simply staring at a generic card with no monetary value of its own, can remind you to spend less overall, since all of a sudden the money is real, and real valuable at that.

Financial guru Ramit Sethi, for example, lost his credit card, and spent nothing but cash until a replacement came. He reported spending 18% less when forced to watch his green wad dwindle in real-time.

Some Places Still Don't Take Plastic (or Require a Minimum Purchase Amount)

Amazingly, over half of all small businesses won't take cards, likely because they can't afford the fees.

It's always good to keep at least some cash on you in case you need to make a purchase from one of these places.

Even if they accept cards, some of these businesses might only do so if you spend X amount, in order to override the fee.

If you entered the store to spend more than the minimum amount, then swipe away. But if you only want a loaf of bread, and they want you to spend $10 before they'll accept your card, just pay for your bread with bread.

That all being said though, there are several cases where plastic owns cash. Here are a few of those:

Online Purchases

Increasing amounts of items can now only be purchased online and with a credit card, or at the very least are extremely difficult to cover with cash.

Plane tickets, while still technically available at a travel agent's physical office, are usually much, much cheaper online, where you can't obviously use cash. The same thing goes for e-books, MP3s, subscriptions to streaming sites, and the like.

The more you shop online, the more reliant you will become on cards in your everyday life.

types (like Savings Account, Checking Accounts).

The Output: Report on Number of Savings Account, Number of Checking accounts and their

total balances, avregae balance, maximum and minimum balance etc

Processing:

Read the file data

Consider valid account data

Separate different accounts

Calculate the sum of their balances

Calculate the average balnace for each type of account

Display the information

Solution:

1.The application should be able to read the csv file.

2.All the error checking should be done as per defined rules

3.The report should be generated in the defined format

4.Data display precisions need to be followed.

5.Interactive errors should be reported with proper messages

6.Integrity of the data should be maintaied while saving the data.

7. Calculation of the averageAccountBalance = (Sum of all the balances of a particular type of account)/(number of that type of account)

8. TotalAccountBalance = Sum of all the balances of each type of account.

9. To find maximum start with a default value and then traverse all the accounts and update the maximum value as per the comparison results

and same for minimum.

Input Validation:

1.Check for the filename (maximum length is 10 chars besides the csv extension)

2.account number (12 digits, first three entries are alphabets)

3.Name (Only alphabets are allowed)

4.Phone Number (7 digits must follow the format xxx-xxx-x)

pesudoCode:

Input filename

open the file

declare accounts[] array

Read the data in accounts and update numOfAccounts

declare numOfAccounts, numOfSavingActs, numOfCheckingActs, totalBalanceSavings, totalBalanceChecking, averageBalanceChecking

averageBalanceSavings, maximumSaavings, minimumSavings, maximumChecking, minimumChecking

for i = 1 to n:

if (Validate(account[i])):

if account[i].type == "Savings":

numOfSavingActs++

totalBalanceSavings = totalBalanceSavings + account[i].balance

if account[i].balance > maximumSavings:

maximumSavings = account[i].balance

if account[i].balance < minimumSavings:

minimumSavings = account[i].balance

if account[i].type == "Checkings":

numOfSavingActs++

totalBalanceSavings = totalBalanceSavings + account[i].balance

if account[i].balance > maximumSavings:

maximumSavings = account[i].balance

if account[i].balance < minimumSavings:

minimumSavings = account[i].balance

What is the difference between a syntax error and a logical error?
RoseWind [281]
A syntax error can be a simple mistake as a typo or an extra space. A logical error has to do with the code structure, and if it makes sense.

Hope this helps!

i have a bag of trail mix . one half of the bag is peanuts. 1/4 of the bag is chocolate candies , and 1/4 of the bag is died fru
Lelu [443]
In our bag, 1/2 is peanuts, 1/4 is chocolate and 1/4 is dried fruit.

The likelihood of drawing a chocolate therefore is 1/4. 

The likelihood of drawing a peanut is 1/2 and the likelihood of drawing a dried fruit is 1/4.

Thus, D is the correct answer because the 1/4 likelihood of drawing a chocolate is less than the 1/2 chance of drawing a peanut.
