What I needed to do:

Write 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.

Thanks to this tutorial and this post.

So what I did was:

1. I imported the library of fstream
2. In the first function I did a for loop where if i is smaller than the length then with the function to lower the program will change all the letters to lower case.
3. I also did an infinite loop (That’s why it has a 1 as a condition) this loop will only stop if you break it and in this I find the number of bananas of each line, and the program saves that info.
4. Then at the end there is a break to end the infinite loop
5. This function will return the number of bananas in each line
6. Then in the next function I open the text file and read it and I made a counter that counts the accumulating bananas in each line of the text
7. Finally in the int main I have a final counter and this will use the last functions and the return values will be returned.

The last WSQ was to use SciLab for data analysis and to display data for example in charts.

This time I’m not going to explain each thing step by step because there is a pdf that explains everything I will do.

you can make a lot of things like: Obtain the sine, cosine, logarithm etc. of a number, also you can make functions which start with “function” and end with “endoffucntion” and it is very similar to c++.

So this is an example of what I learned with SchiLab of data analysis:

Here I did an analysis if the vectors had equal values, I did a sequence from 20 to 10 where each time there is a -2 (is a loop) and I obtained the value of e/2.

Example of a graph:

I graphed this curve and the linspace is where you put values where the value of x is the smallest, the biggest and the number of values calculated  between them.

The WSQ of last week was to make a program that could read a file and return how many lines and how many characters does it have.

This links were very useful for the use of structs, how to count the lines in a file and to count how many characters .

So what I did was:

1. I included the fstream library ,so that I can read the file, and the string library so that I can use the getline function.
2. Then I created my struct, I named it Results and I declared my two integers that my function will return at the end, which are sum (the number of characters) and number_lines (number of lines).
3. Then I created my function and I wrote Results (to make reference to my struct) and then I named it printResults and in the parameters I wrote Results(the struct)”&” w, which means that any variable that has “w.” will be directed to the struct.
4. I declared my variables that the function will return (sum and number_lines).
5. Then I declared the ifstream “file” and the name of my file in parenthesis which is “TextFile.txt”.
6. Then I did an if loop and the condition was that if the file was open then i would do the following:
7. A while loop and in the condition I included a getline (function that counts the number of lines) and inside the getline the parameter are the ifstream file and the string line.
8. Then inside that loop I did number_lines++, which means that it will give me how many lines by repeating the loop while there are more lines.
9. Then I declared an integer called NumOfChars and I assigned it to the length of the string line (line.length()) (length is another function of the  string library).
10. Then I

What we needed to do in this assignment was to use the first program we did and make functions ( like the addition, difference, division, etc.).

This assignment was easy because I only needed to do simple functions.

1. So the first thing I did was to make my functions, I named them Sum, Difference, Product, Division and Remainder.
2. Then in the parameters I included the integers a and b.
3. And in the return value I put (a+b), (a-b), (a*b), (a/b) and (a%b).
4. Then I made the int main
5. Then I asked the user for two integers and then I printed the results of each function.

Here is my code:

#include <iostream>
using namespace std;

int Sum(int a, int b){return (a+b);}
int Difference(int a, int b){return (a-b);}
int Product(int a, int b){ return (a*b);}
int Division(int a, int b){return (a/b);}
int Remainder(int a, int b){return (a%b);}

int main()
{
int a, b;
cout<<“Please enter two integers:”<<endl;
cin>>a>>b;
cout<<“The sum of these integers is: “<<Sum(a,b)<<endl;
cout<<“The difference between the integers is: “<<Difference(a,b)<<endl;
cout<<“The product of the integers is: “<<Product(a,b)<<endl;
cout<<“The division of the integers is: “<<Division(a,b)<<endl;
cout<<“The remainder of the division of the integers is: “<<Remainder(a,b)<<endl;
return 0;
}

When I run it, it gives something like this:

This week the activity I needed to do was create a program that would ask the user for two numbers, the lower bound and the upper bound, and the program would give the user the sum of all the numbers from the lower bound to the upper bound.

I had some trouble with this because I was a little confused because every program from my classmates or on the internet were different so when Ken explained it in class I understood.

So what I did was:

1. Named 3 integers, x,y and sum.
2. I equaled sum to 0.
3. Then I asked the user for the lower and upper bound.
4. I used a while loop so if the user gave me a higher number in the lower bound the program would ask the user to enter the numbers in the right order.
5. After that I used a condition where if the integers where in the right order there would be a for loop.
6. In the for loop is like instructions, it is stated that while the int i that is equaled to x is less or equal to y the second number , i will increase.
7. And then I equaled sum to i.
8. Finally I printed the sum of the range.

The code:

#include <iostream>
using namespace std;
int main ()
{

int x, y, i, sum=0;
cout<< “Let’s to the sum of all the numbers in a range.”<<endl;
cout<< “Please give me the lower bound: “<< endl;
cin>> x;
cout<< “Please give me the upper bound: “<<endl;
cin>> y;

while (x>y){
cout<<“Please enter the numbers in the right order (from small to big).”<<endl;
cout<< “Please give me the lower bound: “<< endl;
cin>> x;
cout<< “Please give me the upper bound: “<<endl;
cin>> y;
}

if(x<=y){
for(int i=x; i<=y;
