How can I do this? 😭

Question

Write a program that allows you to input students' scores and weights. The program should then calculate a weighted average and score based on the data inputted by the user. 

Answer 1

In python just use input function and then do a math.

Answer 2

Hi Iva
Which programming language do you want to do this? (mention in tags please)
Do you have a question related to the coding part or understanding the mathematical formula of weighted average?
If you have a half-ready code to share, maybe we can help out how to complete it.

Answer 3

Sorry I am not very good with CPP, hopefully someone more competent can jump in :)

Answer 4

Hi Iva

Actually I gave this a try and I think this is now working as intended :)
A few points I want to add, in addition to the comments in the code:
* in the sample below the arrays of scores and weights are defined in the code and not from user input. I am not sure how this could be done correctly in Sololearn.
* you need to know in the beginning how many values will be in the array because the variables must be declared accordingly...
* I assumed that the sum of weights is 1 -- however if this is not true then the result must be divided by the sum of weights.

Answer 5

Thank you Tibor 😊🤗

Answer 6

Hi Tibor, c++ I need.. yes for the coding part, #include <iostream>
using namespace std;
int main()
{int n; int M; int S; int A[n]; int i;
cin>>A[i];
i++;
for(i=0; i<n; i++)
{ S=S+A[i];
M=S/n;
Cout<<"average ="<<M<<endl;
} return 0;
}
