i dont have the code right now by the way
i just need logic to make matrix with array thing
matrix in math
example
matrix a[2],b[2];
You don't need code to explain matrix math; just look up what you don't know in math before the test. :s
Is his/her question very vague and unclear?
I really could not answer the question because the question was contradictory. No idea if it is a programming or math question.
No idea what matrix operations where being discussed.
I just wondered if I was missing something, or do the rest of you think the question was too vague.

It doesn't matter. Based on past experience and how the rules are applied we can't help people pass exams anyway.
so it just depend on me anyway,
actually i still had time to studying, the exam started at13.00 in my country
do u know this code use for what
setw
and #include<iomanip.h>
tell me about that
i find it on my friend is computer, that is one of matrix he making
Why not ask your friend?
the question is too vague, maybe the reason is he/she might not be able to express the problem in a proper way...
you can create a 2x2 matrix like this...
What logic do you need???Code:int M[2][2] = {7,10,4,11};
What operations would you like to perform on the said matrix???
They should both work the same, unless there is a bug in the compiler, except that being more explicit tends to make it easier to understand and less likely that a compiler might warn about a potential bug.Originally Posted by grumpy

Because he get the c code from others, he didnt understand that
i see, its c++ thing, so its my mistake
lol, i dont know it gibberish or not
lol, what do u mean computer in your question? if u ask OS, its windows 7• Why was the computer on your friend?
• Why do you describe his computer as a matrix that he's making?
lol i didnt describe his computer, i describe the code he was making, and i wonder #include<iomanip.h> and setw()i s for what?
Ah i confused to tell what is i need, and it is over yesterday,
lol i see that, and to printing variables just using printf right
The exam was over and i cant answer the question but its not a big problem
