问题 I am trying to make a simple multiply action in assembly but for some reason i do not see the registers change when the MUL function is marked. mov bx, 5 mov cx, 10 mul cx 回答1: These are called instructions , and they specify operations that are to be performed by the processor. mov is a mnemonic for mov e, while mul is a mnemonic for mul tiply. Other common instructions include add , sub , and div . I trust you can figure out what operation these specify! Most instructions take two

问题 I have these problems about polynomials and I've spent about 4 hours on this, but I just can't get it. I'm new to Python and programming and I've tried working it out on paper, but I just don't know. Write and test a Python function negate(p) that negates the polynomial represented by the list of its coeffeicients p and returns a new polynomial (represented as a list). In other words, write a function that makes the list of numbers negative. Write a Python function eval_polynomial(p, x) that

I use a tag for my view, but it still not work, i can't understand where i made a mistake, please help me. thx. So here a pictures that shows my problem: pic1 Where i've just started an Activity; pic2 Where i've just scrolled down and up

问题 I would like to multiply several columns in my data frame by a vector of values. The specific vector of values changes depending on the value in another column. --EDIT-- What if I make the data set more complicated, i.e., more than 2 conditions and the conditions are randomly shuffled around the data set? Here is an example of my data set: df=data.frame( Treatment=(rep(LETTERS[1:4],each=2)), Species=rep(1:4,each=2), Value1=c(0,0,1,3,4,2,0,0), Value2=c(0,0,3,4,2,1,4,5), Value3=c(0,2,4,5,2,1,4

For example, What should I do to do 6 x (5+5+5) and get 90 ? 回答1: Use <input type="number"> , define a global variable to store

问题 Is it possible to multiply a char by an int? For example, I am trying to make a graph, with *'s for each time a number occurs. So something like, but this doesn't work char star = "*"; int num = 7; cout << star * num //to output 7 stars 回答1: I wouldn't call that operation "multiplication", that's just confusing. Concatenation is a better word. In any case, the C++ standard string class, named std::string , has a constructor that's perfect for you. string ( size_t n, char c ); Content is

问题 I have an embedded 16 bit CPU. On this machine ints are 16 bit wide and it supports longs that are 32 bits wide. I need to do some multiplications that will need to be stored in 64 bits (e.g. multiply a 32 bit number by a 16 bit number). How can I do that with the given constraints? I do not have a math library to do this. 回答1: A suggestion in C. Note that this code probably will be easier to implement with inline assembler as carry detection in C doesn't seem that easy // Change the typedefs
