Using repeating loops to calculate profits

Write a program which calculate the total profit/year by the end of each month in a year, given the variable P which stores profit/month for that year:

P= [10 7 5 4 6 8 1 6 8 5 11 12]*1000

Set up a loop to calculate Ptotal(i+1)=Ptotal(i)+P(i+1), to help decide about start/end conditions, use an iteration table.

clear

clc

P= [10 7 5 4 6 8 1 6 8 5 11 12]*1000;

Ptot = 1;

for i = 1:length(P)

if Ptot(i)==1

Ptot=P

else

Ptot(i+1) = Ptot(i)+P(i+1)

end

end

disp(Sum);

Could someone help me with this, i've been stuck on this question for a while and just kind of lost? I did a similar question earlier and got the right answer but because the index is start at 0 instead of 1 is making me kind of confused on how to go about this question?

Thanks for the help!

You can follow this code for understanding about start/end conditions

P= [10 7 5 4 6 8 1 6 8 5 11 12]*1000;
Ptot(1) = P(1);
 
for i = 1:length(P)-1
    Ptot(i+1) = Ptot(i) + P(i+1);
end
disp(Ptot)      

       10000       17000       22000       26000       32000       40000       41000       47000       55000       60000       71000       83000

You can initialize Ptot(1) with P(1) and run the loop till length(P) - 1 because you are incrementing Ptot by i+1.
