Sample Question 2

In the Nigerian Federal universities, the grading system is used to calculate the performance of the students. In one particular university the grading system is as follows:

Course code: This is the shorthand representation of the course name. For instance, in the university "An Introduction To Calculus" is given the course code MTH121.

Credit hour: This is the contact hour or weight assigned to the course, as an example MTH121 is given the credit hour of 4.
Workload: Workload is the sum of all the credit hours of the courses offered by the student in a semester. Students are allowed a minimum of 15 units and maximum of 24 units per semester.

Letter grade: These are the letters attached to a score bracket. A scores within a particular range is given the same letter grade: For instance the score bracket in % of the university is given as follows: (70-100) = A, (60-69) = B, (50-59) = C, (45-49) = D, (40-44) = E and (1-39) = F.
Grade points: These are the point values assigned to eache letter grade. For instance, in the same university the grade points are as follows:
A = 5, B = 4, C = 3, D = 2, E = 1 and F = 0.

Quality point: The quality point is the product of credit hours and its corresponding grade point. This means multiplying the credit hour by its grade point. In our example, if a student scores 75 (A) in MTH121 the grade point will be 4 * 5 = 20.

Grade Point Average(GPA): This is calculated as follows, GPA = Total quality point/total workload for the semester

Cumulative Grade Point Average(CGPA): Mathematically, this is expressed as CGPA = (First semester GPA + Second semester GPA) / 2.

If you are still confused about grading system, browse the internet for details.
Note: the grading system may vary in different universities, but the algorithm for calculating GPA (grade point average) and CGPA (cumulative grade point average) remains the same.

Write a program that can calculate the GPA of any semester and the CGPA of the session, your program should be able to allow one to write the result to file and read result from file as well. You may consider making the output visually appealing by using string methods. For instance the output may appear like this:

MTH121----------------------A
PHY121---------------------- B
CHM121-------------------- D
.
.
.
GPA ------------------------3.00

I try?
That the GPA... NOT CGPA

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

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

OP, No system I had to use my phone.

The list of possible numbers beginning with the same prefix and ending with the same suffix continues....
My phone is freezing as the counting continues.

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.

Tested on more phone numbers.

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.

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.

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.

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

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?

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?

Stop saying you work on projects that takes months without solving a breeze project.... And yes, you were bragging! the context you used to buttress your point was a bragging context.... A showoff context, typical of those with nothing to place on the table when it matters.
I bet most of this your socalled big projects involves building a wordpress blog or setting up a simple E-com website...

Sorry dude but I'm above biting your bait.
As for you saying I'm bragging, you are simply misinterpreting my statements. I do work on multi month projects. I have never brought that up here ,I only mentioned it to make a point,about the nature of the quiz the op posed. I've seen devs who work on multi year projects. 10+ years! So working on multi month stuff is child's play to them. I never had the thought in my mind that they were bragging. About what? The work took 10yrs. That's it! None of them brought up the issue cuz they were comparing code sizes but they brought it up as a side issue,to illuminate a point. Maybe u r intimidated by hearing me say I work on multi month stuff,get over it . It's typical in this industry and any true coder will in time do projects that spans months or years.

Welcome to Coding Ask and Answer!


Coding Ask and Answeris a place to learn programming by solving problems. Though you may be guided on difficult algorithm, you must learn to struggle with the problem yourself. Anyone can ask questions and answer questions. If you who successfully tackle any problem do us a favour by sending to the group some screenshots of the sample run and a description of the algorithm used.

Here, no one is going to teach you how to develop website or mobile/desktop apps. If need such things consider joining other groups for assistance
Coding Ask and Answer is a place for programmers to consult, share ideas, and solve programming problems. Here we solve problems only!
Solutions from any language is acceptable since any program can easily be translated into other languages once the algorithm is understood.

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!

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)

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.
