"main:" is our requisite main label that symbolizes the start of the program. First 10 fibonacci numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, "But write it in MIPS assembly!" Oh. My goal is to take user input as n and print the Fibonacci number at n. What I have so far is below. If you run this program and type this in: and hit return, the memory in the computer at the point referenced by theString will look like the following. The address "theArray($t0)" will address theArray, but offset by $t0 bytes, that is the address referenced by the label "theArray" plus the contents of register $t0. I ran this program, and look what memory contained after execution. You appear to have misunderstood the algorithm (or just implemented it incorrectly). 566), Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. The blocks are adjacent, and so are the bytes in memory.
