Hello, Young Padawans!

This time I bring you the third most difficult WSQ (in my opinion).

The WSQ09 ask us to open a text file, count how many lines doest it has, and how many characters.

When I first saw it I say “Whaaaat?! How am I supposed to do so?”. But with the help of Ken and my friend Adal, I found the way.

Well, first of all, is very important that you do some research by your own in google, about how to open files and about structures (are very handy in this assignament). Remember, as Ken said: “Stack Overflow and cplusplus.com are your friends”.

A structure is a format that let you storage several variables, even of different types, inside one concept.

And, you will also need the library <fstream>

As you can see in my code, I made a struct named “info” in wich, I saved 2 variables of “int” kind.  After you research, you may see that there are some commands that let you do the exat thing you wanted to do, just like open the file, conunt the lines, and so and so. I hope yu get the syntaxis of this code.

Hello, Young Padawans!

I know it´s been a lot since I wrote a blog. But, here am I. Then, let´s begin.

This time I bring you the WSQ07, wich involves the use of Arrays. An Array is a set of characters (numbers in this case) wich give every character a number and an order. In order to use them we use: “[]”.

This WSQ ask us to take a list (array) data, sum its numbers, the average of them, and the standard Deviation.

The Standard Deviation is basically, the average of difference between each number and the actual average. You can read this information here:

https://en.wikipedia.org/wiki/Standard_deviation

First, I will put the photo of my code, then I will explain it.

As you can see, it´s all about “fors”. So, you first make a loop with a variable “i”, wich starts in 0 and add one to it until is lower than 10. You just have to add a variable to sum all the terms for every loop.

Then, to get the average, just divide the summatory of that variable by 10. And for the satandard deviation just follow the formula.

After you think about it, you realize it is quite simple.

“Funciones y arreglos”

En este programa hice una función que calcula el promedio de un determinado rango de números elegidos por el usuario. Para lograr esto declare un Array que me permite darle un valor numérico a cada posición del arreglo el cual puedo delimitar con un “for” y una variable como limitante llamada “Cuantos” en este código.

Dentro de la función float PromList(){} hacemos la operación matemática sumando todos los valores de cada posición de los arreglos y dividiéndolos entre la variable Cuantos, para obtener el promedio.

Codigo:

#include <iostream>
#include <cmath>
using namespace std;

int arreglo[100];
float Promedio = 0;
float PromList();

int main() {
cout << “Este programa Calcula el promdio de una lista” << endl;
cout << PromList();
return 0;

}
float PromList(){
int Cuantos;
cout << “Cuantos numeros ingresara?” << endl;
cin >> Cuantos;

for(int i = 0; i<Cuantos; i++){
cout << “Para posicion [” << i << “] Numero # = “;
cin >> arreglo[i];
}
for(int i = 0; i<Cuantos; i++){
Promedio = Promedio + pow(arreglo[i], 1)/Cuantos;
}
cout << “El promedio de los numeros ingresados es : ” << Promedio << endl;

return Promedio;
}//Alvaro_246

En este programa hacemos una pirámide con alguna altura determinada por el usuario, Para ello utilizamos 2 for (int=0; i<Altura; i++) que son los que se encargan de hacer un Loop que determina la cantidad de caracteres que tendrá como base. Esto se encuentra dentro de una funcion llamada int Triangulo(){}

Este es mi codigo:

#include <iostream>

using namespace std;
int Triangulo();

int main (){
cout << “Este programa dibuja una piramide de alguna altura en especifico” <<endl;
cout << Triangulo() << endl;

return 0;
}
int Triangulo(){

int Altura;
cout << “Ingresa la altura de la piramide” <<endl;
cin >>Altura;

cout<<endl;
cout<<endl;

for(int i = 0; i<Altura; i++){
for(int j=i+1; j>0; j–)
cout << “TTT”;

cout << endl;
}
return 0;
}//Alvaro_246

Good evening to all who are reading this.
This course seemed a bit strange at first because the methodology used by Professor Ken seemed a little outside the TEC line, but now I realize that it is very well implemented by Professor Ken, I can tell you about the teacher , Is great in all aspects, as a student more, yes, never misses classes hahaha, I thank the teacher for teaching us the program in a fun and non-restrictive way like the other teachers who give it.
Is a totally different course, but if you think that by doing nothing you are going to learn, you are totally wrong, this course is programming and as such you have to dedicate your time to go over the tasks that the teacher proposes. In conclusion I give it a 100!

This #wsq12 consisted in calculating the eulers constant and print the number with the precision that the user wants. In order to do this program I saw other student posts and saw the function “setprecision” which made the rest pretty easy. The program is below.
