→Part 1: Auto-Vectorization
#* The output will contain sections that start with "Analyzing loop at vol1.c:###" where ### is a line number.
#** If the section ends with "note: not vectorized: ''reason''" then the loop is not vectorized, and the ''reason'' will explain why.
#** If the section ends with "note: LOOP VECTORIZED", then the loop was vectorized (compiled to use SIMD instructions).
# Examine the output to see which loop(s) are vectorized.
# Modify the code so that one more loop is vectorized.
