Hello everyone and welcome to my WSQ07 Blog. Well here’s where I found a little more challenging tasks, so we have to really start trying things and doing a little research if we want things to go well.

WSQ07 was more complicate for me because I’ve never seen vectors or arrays, which are the main things that we’ll need for this assignment. What we had to do was: Create a program that asks the user for 10 numbers  (floating point). Store those numbers in a list. Show to the user the total, average and standard deviation of those numbers. For the final part, we had to make our program work not for only 10 numbers, but for ‘n’ numbers.

NOTE: I made this program with arrays, so if you want to check it with vectors you may want to check someone else’s Blog, reading the chapter of the book about vectors etc.

You may want to check this things before trying to do the program:

• I started reading again our book, and as ken says it’s actually useful, not only for this topics, but for all our programming in general, I swear It’ll help you a lot, it’ll make things easier.
• Super useful information about arrays that may not be found in our book:
  Arrays
  Declare array without specified size
• You’ll need cmath library for doing the standard deviation (you don’t need it by force but it’s easier).
• Remember your for conditions and really, READ THE BOOK.

As you saw from the links I gave you about arrays, you have to declare it first, we leave it alone because we don’t know the amount of spaces (numbers) we’ll need, actually the user will give us that information. Then, inside the main you may

Hi! it’s me again, ok so in this program what we did is that we asked the user for 10 numbers and we give them the total, the average and the standard deviation. Honestly this was hard, I didnt know how to do it, but I learned the “for” loop, so that is good, I’m learning new ways to program.

here’s my code

#include
#include using namespace std;
int main (){
float lists[10], sum=0, average, stdev1=0, stdev, stdev3;
cout<<“hey! please give me 10 numbers”<<endl;
for (int i=0; i<10; i++){ cin>>lists[i];
sum=sum+lists[i];
}
average=sum/10;
for(int i=0; i<10; i++){
stdev+=pow(lists[i]-average,2);
}
stdev=sqrt(stdev/(10-1));
cout<<“the total is “<<sum<<“, the average is “<<average<<” and the standard deviation is “<<stdev<<endl;
return 0;
}

and here’s how it works:
