var Ourarray= new array(alist);

Ourarray.foreach(

processNumbers(alist)

From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.

What is the easiest way to deploy a C++ program to a user’s computer? a. Copy the source code to the user’s computer and then compile it b. Create a batch file that copies the program to the user’s computer and then run it c. Copy the executable file to the user’s computer d. Create an installer program and then run it on the user’s computer

Answers

Answer:

c. Copy the executable file to the user’s computer

Explanation:

When you run a c++ program, an executable file (.exe) is created in the same directory with the source file.

To deploy this program on another system, you need to transfer the executable file from the original system where the program was executed to the new system.

The program will work fine without errors.

However, do not mistake the executable file for the source file. The source file ends in .cpp.

a. In cell 15, enter a formula using the AND function that tests whether the Wireless value is equal to "Y" and whether the Discount value is equal to "Y".
b. Fill the range 16:118 with the formula in cell 15.

Answers

Solution :

'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.

Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true.  If one of the P or Q is not true, then outcome result will be false.

In the context, Kamal wishes to offer a new and more favorable contracts to the business customers who use a wireless services and receive a discount.

Therefore, using the AND operation of the customers as :

Customer     Wireless     Discount     Outcome

   A                   N                   N             FALSE

   B                   Y                   N             FALSE

Why are data silos problematic?

Answers

Answer:

Hampers collaboration

Resource wastage

Lack of data integrity

Explanation:

Data silos comes into play When different departments of an orgainiziations independently collects data needed for its operations. The finance, HR, administrative departments and so on collects their data and keeps it to themselves. As a result there is a repetitive and needless gathering and storage of already existing data, that is the data required by one group will have to be gathered again while it currently exists with another group. This leads to inefficient resource management and wastage. This practice also leads to data integrity as data stored differently across departments becomes inconsistent and less accurate over time. Team work and collaboration is gradually eroded as each group continues to hold on to its resources which poses a problem towards organizational growth.
