sum from one to n

Write a loop that adds up every integer from 1 to n and prints the total.

The starter sets n to 10 and leaves a running total and a counter ready in registers. Fill in the loop body so it adds each value from 1 through n into the total. The program already prints whatever the total register holds.

what is checked

  • the total is printed on its own line
  • the program exits cleanly
  • the total is built up in the loop, not written in as a constant
