conditional-statements

How should I write such an if statement in assembly? if ((a == b AND a > c) OR c == b) { ... Platform: Intel 32-bit machine, NASM syntax. Update For variable types and value, use whatever is more easy to understand. Integers would works fine for me, I guess. In generic assembly, it will be basically something like this ( a in ax , b in bx , c in cx ): cmp bx, cx jeq istrue cmp ax, cx jle isfalse cmp ax, bx jeq istrue isfalse: ; do false bit jmp nextinstr istrue: ; do true bit nextinstr: ; carry on If there's no false bit, it can be simplified to: cmp bx, cx jeq istrue cmp ax, bx jne nextinstr

I'm having a bit of an issue by using Conditional Statements in PHP separated by HTML code. This is the type of code I'm trying to write. This is a profile page and it should only be seen by the user whose profile it is (i'm using session variables for checking that) : <?php if(check if user is logged in) ?> <display users profile in html> <?php else ?> <display an error> But this doesn't work. I also tried using the shorthand notation by putting a : at the end of the if and using the endif statement, but it didn't work. ( On an earlier project , the : method worked for foreach and endforeach

This question already has an answer here: How to test multiple variables against a value? 22 answers I am a total beginner and have been looking at http://en.wikibooks.org/wiki/Python_Programming/Conditional_Statements but I can not understand the problem here. It is pretty simple, if the user enters y it should print this will do the calculation although I get a syntax error on IF answer=="y" answer = str(input("Is the information correct? Enter Y for yes or N for no")) proceed="y" or "Y" If answer==proceed: print("this will do the calculation"): else: exit() Even once you fixed the mis-cased

Unable to understand. Why output is "equal" code: if (-3 == ~2) Console.WriteLine("equal"); else Console.WriteLine("not equal"); output: equal Because two's complement bit-arithmetic makes it so Cribbed from the wikipedia page and expanded: Most Significant Bit 6 5 4 3 2 1 0 Value 0 0 0 0 0 0 1 1 3 0 0 0 0 0 0 1 0 2 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 -1 1 1 1 1 1 1 1 0 -2 1 1 1 1 1 1 0 1 -3 1 1 1 1 1 1 0 0 -4 So you get: 0 0 0 0 0 0 1 0 = 2 1 1 1 1 1 1 0 1 = -3 And as you can see, all the bits are flipped, which is what the bitwise NOT operator ( ~ ) does.

I have a create statement for some models, but it’s creating a record within a join table regardless of whether the record already exists. Here is what my code looks like: @user = User.find(current_user) @event = Event.find(params[:id]) for interest in @event.interests @user.choices.create(:interest => interest, :score => 4) end The problem is that it creates records no matter what. I would like it to create a record only if no record already exists; if a record does exist, I would like it to take the attribute of the found record and add or subtract 1. I’ve been looking around have seen

How do I make a: if str(variable) == [contains text]: condition? (or something, because I am pretty sure that what I just wrote is completely wrong) I am sort of trying to check if a random.choice from my list is ["",] (blank) or contains ["text",] . You could just compare your string to the empty string: if variable != "": etc. But you can abbreviate that as follows: if variable: etc. Explanation: An if actually works by computing a value for the logical expression you give it: True or False . If you simply use a variable name (or a literal string like "hello") instead of a logical test, the

I was wondering what is the performance benefit of using condition variables over mutex locks in pthreads. What I found is : "Without condition variables, the programmer would need to have threads continually polling (possibly in a critical section), to check if the condition is met. This can be very resource consuming since the thread would be continuously busy in this activity. A condition variable is a way to achieve the same goal without polling." ( https://computing.llnl.gov/tutorials/pthreads ) But it also seems that mutex calls are blocking (unlike spin-locks). Hence if a thread (T1)
