How would I write code to add 1 the first value in memory, which will be found at 0x1001000
Store this value in the adjacent word, and also place a copy of this value in register $v0
-By default, the value 0xcafebee will be placed at address 0x1001000. Your program must add 1 to the value found at address 0x1001000. For example 0xcafebeee incremented by 1 is the value 0xcafebeef. This answer will be placed in two places:
the adjacent word space, and in register $v0.Do NOT change the .data segment. All of your work MUST be contained in .text

I have a hier block that takes as a parameter the length of the input vector that is fed to the block from a top level flowgraph and uses it internally, such as to specify the Pad Source vector size. But GRC would give me source/sink IO size mismatch error whenever the value of the parameter set in the top flowgraph does not match the initial/default value set for the parameter in the hier block. The initial value set in the hier block should not matter as it should take the value passed in from the top flowgraph. But it does not appear so in this case as GRC seems to use this initial value to determine the Pad Source vector size and hence produces an error message saying the expected input size does not match that of its source. How would I go about solving this problem? Thank you.
I would like to declare
int A[] = {1,2,3,4,5,6,7,8,9,10} in c language as mips.
Here's my code, please give me a solution.
A: .word 1,2,3,4,5,6,7,8,9,10
Is it right?
yes, it's right, then you can use A as the addresss, and A+offset to get the position of every element.
We want input type number to have the min and max values to take 001 and 009 (with leading zeros) as values in the input box.Is there a way to customize it?
I have a csv file with the following format.
Label 1, 20
Label 2, 10
Label 3, 30
.
.
.
LabelN, 5
How do I plot the second column using the labels given in the csv file as labels on the x-axis?
(Something like this, where 1891-1900 is a label)
EDIT:
Found these questions which are quite similar to mine,
Plotting word frequency histogram using gnuplot
Gnuplot xticlabels with several lines
After trying the commands given in answer 1.
set xtics border in scale 1,0.5 nomirror rotate by -90 offset character 0, 0, 0
plot "data.txt" using 2:xticlabels(1) with histogram
I'm getting a not so clean histogram because the number of labels is quite large. I've tried the formatting given in answer 2. Can anyone suggest a way to get a cleaner histogram?
You have several options:
Plot only the important labels (extremes, mean etc. for example)
Skip every 5th label or so if labels form a series
Split your graph if you must plot every single label.
Seems like case 2) applies here, and thus skipping some of the labels before plotting will make the plot look better.
You can pre-process the file to skip every 5th label (say) using something like the following script:
line_number = 0
for line in open("d1.txt", "r"):
line_split = line.split(",")
if(line_number % 5 == 0):
print line,
else:
print ",",line_split[1],
line_number += 1
You can now plot with appropriate font size
set xtics border in scale 1,0.5 nomirror rotate by -90 offset character 0, 0, 0
set xtics font ",9"
plot "d2.txt" using 2:xticlabels(1) with histogram title "legend_here"
I have an array of questions for an interactive quiz game. When you answer a question, functionally I want that question to be removed from the array (cat4Questions) so that it won't come back for the player so I tried to splice it.
I wasn't sure if it was working so I traced the array. While I was expecting "question1, question2, question3, question4" to be traced, "question1, question2, question3, question4, question5" was the result of my trace.
This is the line of code where I try to splice the array:
cat4Questions.splice(cat4Questions.length,1);
trace(cat4Questions);
You should take a look at shift() and pop() array methods.
shift()
Removes the first element from an array and returns that element. The remaining array elements are moved from their original position, i, to i-1.
pop()
Removes the last element from an array and returns the value of that element.
In your case, you probably need the pop() function to remove the last element of the array.
Arrays are zero-indexed, so you should use Array.length-1; to get the index position of the array.
cat4Questions.splice(cat4Questions.length-1,1);
trace(cat4Questions);
trace now.
You are probably going to remove items other than the last item in the array. If for example the user answers another question.
You can use this code to remove any question:
cat4Questions.splice(cat4Questions.indexOf(question), 1);
Edit
As I said in the comments below, you don't really have to look at the performance of this. But here is how to use pop instead of splice.
cat4Questions[cat4Questions.indexOf(question)] = cat4Questions.pop();
You can also remove the calls to pop and indexOf because they are not efficient either
lastQuestion = cat4Questions[--numQuestions];
cat4Questions[question.index] = lastQuestion;
lastQuestion.index = question.index;
Where question is the question to be removed, index is the index of the question (you have to keep track of that) and numQuestions is the total number of questions. This way, you never use length, indexOf, pop, splice, ...
