Hello again, now I’m posting about my quiz 6 of the course. On this time, we have to create a program who can give the great common denominator between two numbers that the user enter into the program, here the instructions:

The function should receive two integers and return an integer.Obviously you should test your function, so create a main program that asks the user for two values, calculates the gcd and displays that.

It wasn’t too difficult, because we just need an if conditional and a while loop to make the cicle and find the greatest common denominator between the two numbers, and here, the code:

And the program on terminal running:

Don’t forget to look my codes on github so you can use it and learn how to make it, also you can add comments !!

Hello people.

I am here to post about the quiz that I made some days ago about two programs: One which has to:

1. Create a function called is_palindrome which receives a string as a parameter and returns true if that string is a palindrome, false otherwise. Remember that a palindrome is a word that is the same forward or backward. For full points your function must ignore case and must work with any character (not just letters). So (“Dad$dad” is a palindrome even though the D is capital and d is lower case).

On this program I learned how to use vectors and make a palindrom with it, taking the word and then taking the reverse of the word, Yeah, vectors rules.

To learn more about vectors on C:  http://www.cplusplus.com/reference/vector/vector/

Here my code:

Running:

And the second one:

1. Create a function called find_threes that receives as a parameter a list (or Vector or array for C++ students) of numbers and returns the sum of all numbers in that list that are evenly divisible by 3. Note if using vectors, you will need an additional parameter to represent the number of numbers in the array. So if the list was [0,4,2,6,9,8,3,12], the function would return 30 (0+6+9+3+12)

Here, we have to use an array to get the range of numbers that we are going to use in our function “threes”. It was a little bit difficult but with the help of other students of the class I can make it.

The code:

And running:

Hello people, I was busy for a long time but here I am. This post is about my first quiz of the second partial of the semester. It was not too difficult but I got in trouble with some parts of the code but I finally did it. Well, the instructions for the quiz were:

Create a function called euler_calc with a single parameter precision. The value of precision is used to determine when to stop calculating. Your calculation will stop when the two consecutive values estimating e differ by less than precision (remember to use absolute value when calculating the difference between two values here).

I search information on Wikipedia about the Euler number to get the idea, and I found interesting information about it: The number e is an important mathematical constant that is the base of the natural logarithm. It is approximately equal to 2.71828,[1] and is the limit of (1 + 1/n)n as n approaches infinity, an expression that arises in the study of compound interest. It can also be calculated as the sum of the infinite series.

Thanks Euler for doing our life easier and harder at the same time.

Here the code of my program.

The new thing here was the SET PRECISION function that I used to call to the user for the number of decimals that he wants to use.

It has to look like that:

#include <iomanip>      // std::setprecision

int main () {
  double f =3.14159;
  std::cout << std::setprecision(5) << f << 'n';
  std::cout << std::setprecision(9) << f << 'n';
  std::cout << std::fixed;
  std::cout << std::setprecision(5) << f << 'n';
  std::cout << std::setprecision(9) << f << 'n';
  return 0;
}

**Don't forget to use the iomanip library to run it without problem.

And the program running:
