# Babylonian Method.

* --Originally published at Loading…*

In this assignment we had to:

write a function to calculate the square root of a number using the Babylonian method.

When I read it, I thought this would be a bit difficult, buuuuuuut it was pretty easy. First I investigated about this method, and this page is really good if you want to know about it. Also I found this flow diagram that helped me a lot:

So, the first thing that I did was add the **<cmath> **library. Then following the flow diagram I made my function. I established two variables, the **b **for the result, and **dif **for the diferencial. First we equate **b** with **x**, then made an operation in order to obtain the **dif, **if **dif **isn’t it less that 0.00001 the program prints the **b**, and made an other operation to give another value to **b **to get closer to the square root of **x, **and made the same until the condition is satisfy.

And here is how it works:

Hi!! Is almost the ending of this semester and I promised not to leave everything to the last minute… but here I am… doing all in the last minute.

Today I’m going to explain how I did the **#WSQ09. **To make this program I asked for help to my friend Jenifer Romero, she explained me everything, but the problem was that we did it on her Mac, so… I had to make some arrangements in order for it to work in my Windows computer.

This is what we had to do:

So for this assignment I would like to see you create a function that receives as parameter the name of a file (this would be a string value like data.txt) and your function counts the number of lines and the number of characters in the file which it returns as a single value (but with two values). You will want to look at how to create/define and return a struct value from a function and how to open and read text files line by line

The first thing I did was to add the two necessary libraries **<fstream> & <string>. **Then, for make the *“it returns as a single value (but with two values)”* part, I added a **struct **that I called

*datos*, which stores two

**int**,

*(for lines) and*

**l***(for the characters). Next, in my function (*

**c****func**) which receives the string url (or ruta) and called the struct. After that I wrote

*it associates it with the file name and opens it. I established my variables (at the final I don’t use the*

**ifstream archivo(ruta.c_str(), ios::in)****char**car, ‘cause Ken helped me to do the same with less), and wrote a

**while**for do the things until the

# #WSQ12 Estimating e 15/04/17 and WSQ12.cpp

* --Originally published at Solving Problems with Programming*

So in this fourteen week class I started with doing this WSQ12 I started reviewing in creating and calling functions in C++.#Mastery06, #Mastery07, #Mastery16 Use of recursion for repetitive algorithms, #Mastery17 When to use what type of repetition in a program, #Mastery18 Creation and use of Arrays/ Vectors in C++. Furthermore, in this stage I have all the topics of the course from 1 to 22.

What I did for this numeric program is solving the problem to the user by creating a program with writing this assignment where I will estimate the mathematical constant e. I should create a function called calculuate_e which receives one parameter called precision that should specify the number of decimal points of accuracy.

I will want to use the infinite series to calculate the value, stopping when the accuracy is reached (previous and current calculation are the same at the specified accuracy).

Hence, the resources I need it to solve this program are here:

For doing this tutorial you need to do the factorial, therefore you need to see my tutorial #WSQ06 Factorial Calculator 12/02/17 and WSQ06.cpp

And the next picture shows us how the number e is calculated with infinite series and I will do this infinite serie in c++

The following photograph shows the solution to this problem:

So in this fourteen week class I started with doing this WSQ11 I started reviewing in creating and calling functions in C++.#Mastery06, #Mastery07, #Mastery16 Use of recursion for repetitive algorithms, #Mastery17 When to use what type of repetition in a program, #Mastery18 Creation and use of Arrays/ Vectors in C++. Furthermore, in this stage I have all the topics of the course from 1 to 22 including #Mastery22 Matrixes and vectors because in this code I use a matrix with a dimension of 1.

What I did for this numeric program is solving the problem to the user by creating a program with writing a function called find_bananas which receives a single parameter called filename (a string) and returns a positive integer which is the number of times the word (string) “banana” (or “BANANA” ) is found in the file. The banana can be any case (‘BaNana’ or ‘BANANA’ or ‘banana’, etc) and they can be “stuck together” like “banAnaBANANA” (that counts as two). Create your own test file (plain text) to check your work.

Hi! I know it pass a long time without posting anything, sorry I’m in that point of the semester trying to save it.

And I know maybe this post would be more useful the last week, before the partial, but… I hope it could help you.

### 1. Distance again.

Actually I’ve already explain this code, and I do the same in this quiz, so I’m not going to explain this one, but here is my code:

### 2. T’s pyramid

This one was kind of difficult because one of my functions was wrong, but technically it’s veryyyy easy.

I only use the library **<iostream>**, but I used two functions. The first one was for print the T in each line, for this I used an **if** and a **for, **which simply is adding one T in each line of the pyramid. The second function is for print how many lines must have the pyramid, so I use two **for, **one to increase **f** (fila) while it’s smaller than **n**(the number that the user enter). And the other one to decrease **f**, when it is the same as **n** and until **f **is 1.

### 3. n!

This one I’ve already explained too, so like the first one, I’m not going to explain it. The only difference is that I made this code more simply like the one that is in the link.

### 4. Average list

This one was kind of easy. First I established the libraries **<iostream> **and **<cmath****> **and as always put the **using namespace std;. **Then, I created a **float **function named *promedio_lista *that receives the **sum **and returns the **prom. **Next, in my **int main **I established two kind of variables, in the *float *I put the array **cal[7] **(this ‘save’

So in this twelve week class I started with doing this WSQ10 I started reviewing in creating and calling functions in C++.#Mastery06, #Mastery07, #Mastery16 Use of recursion for repetitive algorithms, #Mastery17 When to use what type of repetition in a program, #Mastery18 Creation and use of Arrays/ Vectors in C++.

You can search for that method, it will be easy to find. Hence, you can have it here in the survey that we did last week:

Then, we need that this the function should receive a number and return floating point number. Obviously you should test your function, so create a main program that asks the user a value, calculates the square root and displays that.

Hence, the resources I need it to solve this program are here:
