MIPS Programming

Use the MARS simulator to write and test a MIPS assembly language program that extends your [login to view URL] program from an earlier assignment as follows: • Name the new program avggrade.asm. • Continuously extract grades from standard input until a negative value is entered. • Compute the integer average for all grades entered (truncated). • Determine the corresponding letter grade (’A’, ’B’, ’C’, ’D’, ’F’) using the common ranges. • Print the average and corresponding letter grade to the terminal.
