Answer and Explanation:

Open your text editor and open new file. Save new file file as lastname_firstname_cities.py. The program will open the file cities.txt downloadfile hence :

dfile= open(cities.txt, "r")

If we write this into our lastname_firstname_cities.py file it will open our cities.txt downloadfile in read mode and text mode(by default unless we specify binary mode which is for images)

Explanation:

The grade must be calculated based on following pattern:

Average Mark RangeGrade91-100A181-90A271-80B161-70B251-60C141-50C233-40D21-32E10-20E2

Calculate Grade of Student in C++

To calculate grade of a student on the basis of total marks in C++ programming, you have to ask from user to enter marks obtained in 5 subjects. Now add marks of all the 5 subjects and divide it by 5 to get average mark. And based on this average mark, find grade as per the table given above:

// C++ Program to Find Grade of Student // -------codescracker.com------- #include<iostream> using namespace std; int main() { int i; float mark, sum=0, avg; cout<<"Enter Marks obtained in 5 Subjects: "; for(i=0; i<5; i++)

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

  C                   N                   Y              FALSE

   D                   Y                   Y             TRUE

def summation (num1, num2):

i = 0

for x in range (num1 : num2 + 1):

i += x

return i

print ( summation(l, r))

Answer:

Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed.

The scenario defines a top-down approach to data warehouse design as "Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed".

In the "Top-Down" method system, a data warehouse exists defined as a subject-oriented, time-variant, non-volatile, and integrated data storage for the entire business data from various sources exist validated, reformatted, and saved in a normalized (up to 3NF) database as the data warehouse.

Therefore, the correct answer is option b) Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed.

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.

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.

function processNumbers(alist){

var Ourarray= new array(alist);

Ourarray.foreach(

if(isNaN()){

Console.log( "An element in the list is not a number."};

break;

}

}

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.
