Suppose we wanted to make change for purchases and wanted to use the least number of coins possible. Here is a greedy algorithm:

love history [14]

Answer:

Explanation:

The following code is a Python function that takes in the amount of change. Then it uses division and the modulo operator to calculate the number of coins that make up the changes, using the greatest coin values first.

import math

def amountOfCoins(change):

print("Change: " + str(change))

quarters = math.floor(change / 0.25)

change = change % 0.25

dimes = math.floor(change / 0.20)

change = change % 0.20

pennies = math.floor(change / 0.01)

print("Quarters: " + str(quarters) + "\nDimes: " + str(dimes) + "\nPennies: " + str(pennies))

Prompt

madam [21]

Have you ever tried to learn a new language or do you have friends who've had that experience?

Yes, I tried to learn Python and I even managed to do two Discord bots which are (somewhat) functional, but I'm far to say that I've managed to lean the language completly. There are lots of things to learn on a language as Python.

I also leant PHP on my own and managed to do a website (somehow) functional.

What are some of the steps you would take to learn a new language, and what are some challenges that might arise?

The first steps in learning any computer language is learning the syntax. If you manage to do that, with the experience you gained from previous projects/languages you might be able to create something working. At times you might feel down if the project doesn't work as expected.

What are some things that can help make the process easier?

Video tutorials, experiments and searching questions and problems on Google is a very important resource.

Create a program to deteate a program to determine whether a user-specified altitude [meters] is in the troposphere, lower strat

allsm [11]

Answer:

#include <iostream>

using namespace std;

int main()

{

float altitude;

cout<<"Enter alttitude in meter";

cin >>altitude;

if(altitude<0 || altitude > 50000)

{

cout<<"Invalid value entered";

return 0;

}

else{

if(altitude<= 10000)

{cout <<"In troposphere "<<endl;}

else if(altitude>10000 && altitude<=30000)

{cout <<"In lower stratosphere"<<endl;}

else if(altitude>30000 && altitude<=50000)

{cout <<"In upper stratosphere"<<endl;}

}

return 0;

}

Explanation:

Define a float type variable. Ask user to enter altitude in meters. Store value to altitude variable.

Now check if value entered is positive and less than 5000,if its not in the range of 0-50,000 display a termination message and exit else check if it's in less than 10000, in between 10000 and 30000 or in between 30000 and 50000.

10,000 is above sea level is troposphere.

10,000-30,000 is lower stratosphere.

30,000-50,000 is upper stratosphere.
