Question

Write a MATLAB script file that will sum all the positive entries in V and stop summing once the sum reaches or exceeds 20(while loop). An fprintf statement should be used to display the value for the sum to prove it has reached or exceeded 20, and the number of entries to reach this value should be displayed. V = [7 9 -8 9 3 -8 -5 1 10 10 0 -7]

Reminder: don’t use the built-in function, sum. Use vector indexing

Answer 1

V = [7 9 -8 9 3 -8 -5 1 10 10 0 -7]
total = 0;
i = 1;
while i <= length(V) && total < 20
    if V(i) > 0
        total = total + V(i);
        i = i+1;
    end
end
fprintf("Value of sum is %d and number of entries added is %d\n", total, i-1)
