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’
