Answer:

// you are doing calculations.

Explanation:

Here we add the single line comment i.e you are doing calculations by // forward slash. If you are making a comment more then the single line its better to use /* comments statements */.

For example:

/* print welcome on screen

print in nextline */

Following are the program in c++ language.

#include<iostream> // header file

using namespace std; // namespace

int main() // main method

{

int a=9,b=89; // variable declaration

// you are doing calculations.

int c=a+b;

cout<<c; // display c

return 0;

}

Output:98

You have been hired by an educational software company to create a program that automatically calculates the sum of each place-v

Vinvika [58]

Hi, you haven't provided the programing language, therefore, we will use python but you can extend it to any programing language by reading the code and the explanation.

Answer:

n1 = int(input("First numeber: "))

n2 = int(input("Second numeber: "))

for i in range(5):

r1 = n1%10

r2 = n2%10

print(r1+r2)

n1 = n1//10

n2 = n2//10

Explanation:

First, we ask for the user input n1 and n2
We create a for-loop to calculate the sum of each place-value of two numbers
We obtain the last number in n1 by using the mod operator (%) an the number ten this way we can always take the last value, we make the same for n2
Then we print the result of adding the last two numbers (place value)
Finally, we get rid of the last value and overwrite n1 and n2 to continue with the process

For the question below, refer to the following recursive factorial method.

Mashcka [7]

Answer:

(d) 6

Explanation:

When we call factorial(3) first it will check if it greater than 1 since it is greater then return 3*factorial(2) will be called on factorial(2) it will again check that 2>1 since it is greater then return 2*factorial(1) will be called.In factorial(1) we have is not greater than 1 so it will return 1.return 2*factorial(1) will return 2 and 2 that is returned by factorial(2) will be multiplied with 3.So it will return 6.

A) How could you modify Shelve with a technique discussed in class so that you can create Shelve instances that contain // Tools

Kay [80]

Answer:

See explanation

Explanation:

A “shelf” is a dictionary-like object. A shelf is an arbitrary Python objects, that is; anything that the pickle module can handle. This includes recursive data types and objects containing lots of shared sub-objects. It must be noted that the keys are ordinary strings.

(A). modification to Shelve can be done by following this instructions;

(1). Do not redefine built-in functions,(2). grab shelved item, mutate item, write mutated item back to shelf.

The number (2) instructions is during iteration over shelved items.

(B). CREATING FUNCTIONS THAT TAKES IN TWO SHELVES;

import shelve

d = shelve.open(filename) # open -- file may get suffix added by low-level

# library

d[key] = data # store data at key (overwrites old data if

# using an existing key)

data = d[key] # retrieve a COPY of data at key (raise KeyError if no

# such key)

del d[key] # delete data stored at key (raises KeyError

# if no such key)

flag = key in d # true if the key exists

klist = list(d.keys()) # a list of all existing keys (slow!)

# or, d=shelve.open(filename,writeback=True) would let you just code

# d['xx'].append(5) and have it work as expected, BUT it would also

# consume more memory and make the d.close() operation slower.

d.close() # close it

<em>For many users, uploading files is quite a bit slower than downloading files. This is usually normal, because most high-speed Internet connections, including cable modems and DSL, are asymmetric — they are designed to provide much better speed for downloading than </em><em>uploading.</em>
