"Which course to take" exercises

Example 1

integer w, x, y, z
y = 0
w = 0
read x                // value coming from user    s/x/howMany/
while (y < x)        // y < x is a boolean expression, true or false
  begin
  read z
  w = w + z
  y = y + 1
  end
print w              // w is printed  sum of all the z's   s/w/sum/
end

Example 2

procedure main
integer array x[10]
integer i, j
for (i = 1 to 10 step 1) read x[i]
call test (x, 10)
end

procedure test (x, j)
integer array x[j]
integer i
for (i = 1 to j step 1)
  if (x[i] < 0) print x[i]
end
