MIPS Code as follows:

.LC0:

        .ascii  "Enter the limit:\000"

.LC1:

        .ascii  "Enter the name of \000"

.LC2:

        .ascii  "th student:\000"

.LC3:

        .ascii  "Enter the mark:\000"

.LC4:

        .ascii  "Menu\000"

.LC5:

        .ascii  "1.Minimum\000"

.LC6:

        .ascii  "2.Maximum\000"

.LC7:

        .ascii  "3.Median\000"

.LC8:

        .ascii  "4.Enter your choice:\000"

.LC9:

        .ascii  "Minimum Marks among 5 subject is:\000"

.LC10:

        .ascii  "Maximum Marks among 5 subject is:\000"

.LC11:

        .ascii  "Median among 5 subject is :\000"

.LC12:

        .ascii  "Wrong Choice\000"

Write a MIPS Assembly Language program which runs interactively to convert between decimal, binary, and hexadecimal. 1. Request input data type. 2. Request input data. 3. Request output data type. 4. Output the data. The suggested approach was to take the input data as a string. But I am really lost as to how to process the string and then converting it to another data type. Thanks for the help!

In MIPS only!! make a program that multiplies a user input by 15. YOU CAN ONLY USE ADDITION AND BITSHIFT OPERATIONS. Also very important, make sure its correct by using the mult and mflo operators (!More Important, explain to me how that's done!) . make sure to display user input and display the output. !!!please put comments on each line of what's happening!!!

(MIPS Assembly Language): Write the following sequence of code using *native* MIPS instructions: x = x - y[0] + y[1]; In memory x, y are stored beginning at 0x010000cc. Use registers $s1 for x,  and $s2 for the base address of y. Make sure your code includes all necessary declarations such that it could run in SPIM.

Write an assembly program that reads characters from standard input until the “end of file” is reached. The input provided to the program contains A, C, T, and G characters. The file also may have new line characters (ASCII code 10 decimal), which should be skipped/ignored. The program then must print the count for each character. You can assume (in this whole assignment) that the input doe not contain any other kinds of characters.  the X86 assembly program that simply counts...

Without using move or li, write MIPS assembly language using MARS simulator to print a half pyramid depending on a value n of a user input. Such that if n = 5 were entered the following would be printed: 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5
