Answer:

hope this helps. I am also a learner like you. Please cross check my explanation.

Explanation:

#include

#include

using namespace std;

int main()

{

int a[ ] = {0, 0, 0}; //array declared initializing a0=0, a1=0, a3=0

int* p = &a[1]; //pointer p is initialized it will be holding the address of a1 which means when p will be called it will point to whatever is present at the address a1, right now it hold 0.

int* q = &a[0]; //pointer q is initialized it will be holding the address of a0 which means when q will be called it will point to whatever is present at the address a0, right now it hold 0.

q=p; // now q is also pointing towards what p is pointing both holds the same address that is &a[1]

*q=1 ; //&a[0] gets overwritten and now pointer q has integer 1......i am not sure abut this one

p = a; //p is now holding address of complete array a

*p=1; // a gets overwritten and now pointer q has integer 1......i am not sure abut this one

int*& r = p; //not sure

int** s = &q; s is a double pointer means it has more capacity of storage than single pointer and is now holding address of q

r = *s + 1; //not sure

s= &r; //explained above

**s = 1; //explained above

return 0;

}

A shop will give discount of 10% if the cost of purchased quantity is more than 1000. Ask user for quantity suppose, one unit wi

UkoKoshka [18]

Answer:

The program in Python is as follows:

qty = int(input("Quantity: "))

price = 100 * qty

if qty >1000:

price = (100 - 0.10 * 100) * qty

print("Cost: "+str(price))

Explanation:

This prompts the user for the quantity

qty = int(input("Quantity: "))

This calculates the price or cost, without discount

price = 100 * qty

This checks if the quantity is greater than 1000

if qty >1000:

If yes, this calculates the price or cost, after discount

price = (100 - 0.10 * 100) * qty

This prints the calculated cost

print("Cost: "+str(price))

A7DF is the hexadecimal representation for what bit pattern?

kipiarov [429]

Answer:

1010 0111 1101 1111

Explanation:

A = 10 in decimal = 1010 in binary

7 = 7 in decimal = 0111 in binary

D = 13 in decimal = 1101 in binary

F = 15 in decimal = 1111 in binary

Therefore 0xA7DF = 1010 0111 1101 1111 in binary

Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the avera

aliya0001 [1]

Answer:

In python:

file = open("rates.csv", "r")

ratecount = 0

ratesum = 0

mylist = []

rates = file.readlines()

for nums in rates:

num = nums.rstrip('\n')

mylist.append(int(num))

for i in num:

ratesum= ratesum + int(i)

ratecount = ratecount + 1

print("Maximum Rate: "+str(max(mylist)))

print("Minimum Rate: "+str(min(mylist)))

print("Average Rate: "+str(ratesum/ratecount))

Explanation:

This opens the csv file

file = open("rates.csv", "r")

This initializes the number of rates in the file

ratecount = 0

This initializes the sum of the rates

ratesum = 0

This initializes an empty list

mylist = []

This reads the rates into lines

rates = file.readlines()

This iterates through the rates (as a string)

for nums in rates:

This removes the newline character \n in the rates

num = nums.rstrip('\n')

This appends the rates (as an integer) to the empty list

mylist.append(int(num))

The following counts the rates in the file and also sum them up

<em> for i in num: </em>

<em> ratesum= ratesum + int(i) </em>

<em> ratecount = ratecount + 1 </em>

This prints the maximum of the rates

print("Maximum Rate: "+str(max(mylist)))

This prints the minimum of the rates

print("Minimum Rate: "+str(min(mylist)))

This calculates and prints the average rate

print("Average Rate: "+str(ratesum/ratecount))
