IamTeen:
This?

I used mtnNumbers.setPrefix() function to switch from 0813 and mtnNumbers.setLastNumbers() to change the numbers ending.
mtnNumbers.printNumbers() function did the printing.

Nice!

IamTeen:
Boss, I'm still a learner sir.
Can use mtn.prefChanger() to change 0813.
I forgot converting mtn.prefChanger argument to string...i did in earlier version.
Can use mtn.gen() to generate numbers and ending of choice. I chose 4457.
If no number is specified, it prints without condition.

Good. Can you do this without the pre-knowledge that the sum of the numbers is 10**7? That's the essence of the question, the same thing you did here can be done using Python range but such solution is trivial.

QUESTION


Write a program that converts Roman numerals to Hindu Arabic numerals (0123456789). That's when a user enters a Roman digits like ix or "IX" it should print 9. Visit the internet and download the charts of Roman digit and their corresponding Arabic ones and study the chart. See chart below.


NOTE:

I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1000

These 7 numerals must be handled separately. The remaining numerals follow a certain pattern. See whether you can understand the pattern by studying these two patterns and implement an algorithm for that:

(1)

IX = -1 + 10 = 9
XL = - 10 + 50 = 40
XC = - 10 + 100 = 90

(2)

VI = 5 + 1 = 6
XX = 10 + 10 = 20
LX = 50 + 10 = 60

MrsQ:
Hello Guys, i'm new on this thread but i'll like if i can get directions.
I'm about to start out a career in programming( I have no IT knowledge) and from my research i found out taking comptia A+ course and subsequently getting certification is the starting point.....correct me if am wrong, please. My question is I want to take this course at HIIT plc is it a good idea? whats your opinion about them? Thank you.

You can be a self-taught programmer like me. Perhaps, it works for me because I studied Mathematics in the university. But I don't know whether you have a foundational knowledge of Mathematics. If you don't have it, self-teaching may not work for you because you are likely to get lost at the sight of a simple algorithm and programming problems. If that's the case then you need a tutor or take the said course. Programming is never complete without basic knowledge of Mathematics and logic.
You can go ahead and take the course, if you a need a tutor I can help. Consider joining our new WhatsApp group

TIPS

It is never beneficial to browse the Internet for solutions. It is never advisable because it will render you unproductive and turn you into programming dummy. If you encounter any difficulty in solving programming problems. Browse for How to to do certain things in your programming language in the Internet. Never browse for the Solution itself.
If a certain algorithm or method/formula is required, visit Wikipedia to learn more about the algorithm, like the case of Horner Scheme.

Once again welcome!

I'm still waiting to see the solutions to these problems.

AdolphBrian:
Here's my resolution

Things seem to be working fine though I can't prove everything with that screenshot alone. Run it and print out certain prefixed-numbers that end with certain 4-digit numbers.

QUESTION

In the beginning, at the birth of computing, there were no programming languages. Programs looked something like this:

001100010000000000000000001100010000000100000001001100110000000100000010010100010000101100000010001000100000001000001000010000110000000100000000010000010000000100000001000100000000001000000000011000100000000000000000

That is a program to add the numbers from 1 to 10 together and print out the result: 1 + 2 + ... + 10 = 55. How tedious could this be? This is difficult to understand and write without errors by human beings, but unfortunately that's the only language computer understands the so-called machine language. A we know Computer understands only 0 and 1 and nothing more. Luckily we now have high level languages that human beings can understand and write without errors and compilers/interpreters that can translate the high level languages to the machine language.
As far as computing is concerned the most important things are the two bits: 0 and 1 the so-called binary notation any other things can be converted from from binary notation.

(1 ) Write a program that converts a given number from decimal to binary notation.

(2) Write a program that converts a given number from binary to decimal notation.

(3) Write a program that converts a given number from decimal to hexadecimal notation.

(4) Write a program that converts a given number from hexadecimal to decimal notation.

(5) Modify question number (2) by:

Writing a program that converts a binary number to decimal using the Horner scheme(a.k.a Horner Method )
Search Wikipedia for details on Horner Method.
Horner method is fast and code-efficient. This is how Horner scheme works.
1001 (base two) = ((1 × 2 + 0) × 2 + 0) × 2 + 1 = 2 × 2 × 2 + 1 = 9 (base 10)

Modified.
Add me to the WhatsApp group

Perfect!

Sixtytwo62:
You mean something like this??

I think this is near to perfection. But it is printing 12-digit numbers? Can you screenshot the very beginning of the output? Your coding skill is needed. Have you been added to our WhatsApp group?

modestbrowser:
Will add options for adding second semester results 2.
And calculating CGPA

Wow! This is great. The output looks really appealing. I think I will start studying JavaScript. Please share the source code on the WhatsApp group.

I sent a picture to question 2... Didn't u see it bro

Let me check it.

modestbrowser:
Okay Asin.
Just tell me you don't want to rate it

Please note that you are there already. I said you should modify your algorithm to be print the whole number. It should be like
0813 000 3431
0813 001 3431
0813 002 3431
...etc
I hope you understand me now. Have you joined our WhatsApp group?

modestbrowser:
What u think of my attached picture though.
i.length can show the total number.
Plus JavaScript isn't fit for it.
Will do with python and send

Okay.

modestbrowser:
I try?
That the GPA... NOT CGPA

TYPO ON THE HTML


Number one question:

Solving with JavaScript.

One could easily do.
For(var i=1000000; i<9999999; i++){
Console.log("numPref"+i)}
The problem there is the zeros.
Lemme see it sha....
Plus printing this alone hangs my browser console

I never intended the problem to be solved on the pre-knowledge that the the total number is 10 000 000. Your program itself should be able show the total number.

Sixtytwo62:
I had to break out of loop when the counting reach 200 to take a screen shot. It was impossible at first, as each count updates the screen, throwing me to the bottom continuously.

How can one know that such program outputs the correct phone numbers? I mean how many numbers are you going to manually test to verify that the program is printing correct numbers. That's not how I intended the program to display. Check my previous screenshots on how the output should appear. Your phone can display all the numbers that end with "3431" but it cannot display all the result. Please modify the program.

modestbrowser:
You said CGPA is never rounded up or down
But u rounded yours up

There's no valid calculation in the question. I just used 3.00 to show how the output should look like.

modestbrowser:
I've done second one.
Will post shots soon

That's great. I would like to see the screenshots. And remember that GPA and CGPA are never rounded up or down. That's if you have 3.6795 or 4.5437 in your calculation, then CGP must be 3.67 or 4.54 and NOT 3.68 or 4.50 respectively.

modestbrowser:
But you have time to reply.

My brother I'm shocked that some people can lie in ignorance and hypocrisy. I created this thread to help build Nigerian future programmers. Anyone experienced programmer should sacrifice a little time at least once in a while to help build our future programmers here. If such a person is really experienced then it should not take more than few minutes to come up with an algorithm to solve such problem. Programming is not done by an endless I can's and I will's programming is done by actual implementation.

asalimpo:
Actually this is toy stuff to an experienced hand. It will b tedious but not something to take up much time. Max a few hours. Nothing when compared to projects that chew up months of time. It's unfortunate what nl is despite being a programmer section. It lacks facilities for programmers!

I really need experienced programmers. Please consider dropping your number here so that I can add you to our WhatsApp group. Thanks

modestbrowser:
Let me solve your questions

Okay. Please after solving it consider sharing the screenshots of the sample run of the program. Thanks

hitan:
07061836156

I have added you.

asalimpo:
I could code it up but I'm presently very busy and I don't code in Python.
It's straightforward enough that one can plot the algorithm offhead .
As for the combining d prefix and the tails (I.e the 7 digit numbers) to form a new number,11,digits, all you need is simply string concatenation. Phonenum=Prefix+ tail;
Use a loop to run thru the collection of prefixes to do the same.

Okay! When you are less busy consider writing the codes and check if everything works fine. Initially, I thought the problem was trivial but as I began to approach it, I later found out that it was not that trivial. That is the reason I'm emphasizing on writing the code to get the feel of it yourself.

As improbable as it might seem to you, the basic principles of writing
computer programs have not changed all that much in the past 15 years.
Programming languages change, technologies get modernized, integrated
development environments get more and more advanced but the
fundamental principles of programming remain the same. When
beginners learn to think algorithmically, and then learn to divide a problem
instinctively into a series of steps to solve it, as well as when they learn to
select the appropriate data structures and write high-quality programming
code that is when they become programmers. Once you acquire these skills,
you can easily learn new languages and various technologies.
