CODE DRILL 1 · RUN ONLY
This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.
TASK
Write the sum loop so the complete C++ program reads n = 4 and the values 4 2 7 1 from standard input, then prints only 14.
OUTPUT
Sample14
What a finished answer prints, from the lesson. Nothing has run yet — press Run and this is replaced by your program’s own output.
