[ad_1] The bitwise shift operators are the right-shift operator (>>), which moves the bits of shift_expression to the right, and the left-shift operator (<<), which moves the bits of shift_expression to the left. There are also two complex operators that can be used to assign the value directly to the value on left. These are … Read more
[ad_1] In the line char ** domain[] = new char * [rows]; char ** domain[] tries to make an array of char **. If the compiler didn’t complain about not having a valid array size in the [] and you would have a 3D structure. You want just plain old char ** for a 2D … Read more
[ad_1] x |= -(x == 0); x |= -!x; x = x ? x : 0xFFFFFFFF; if (x == 0) x = 0xFFFFFFFF; … Benchmark and choose what’s appropriate for you 4 [ad_2] solved Bithack for: if x is 0, then x should be -1, else x should be untouched
[ad_1] It would help to see how you push items onto the stack. If you’re really calling pop without a push first, well, then it’s not supposed to do anything, is it? This bit makes me nervous: Node *aux,*prev; prev = *stack; aux = prev->next; if(aux == NULL) { free(prev); return; } You set prev … Read more
[ad_1] VS doesn’t create directories for you. The view you see is “filters”. Organization on the disk is flat unless you tell it otherwise, and it’s moderately painful. The project on github will reflect the directory structure, not VS’s “filters”. 1 [ad_2] solved Visual Studio C++ structure on Github
[ad_1] One way to do it would be to have a new property on your myClass public class myClass { private string _setString; public string setString { get { return _setString; } set { AuditTrail += value; _setString = value; } } public string AuditTrail{get;set;} } Then in your main method you’d put: Console.WriteLine(AuditTrail); 0 … Read more
[ad_1] This is a simple logical error and a problem of “infinite recursion” because the CurrentState property is attempting to set itself. The solution is simple. Currently you have this (simplified) public State CurrentState { set { // … CurrentState = state.Whatever; // … } get { return ???; /// ??? => I don’t know … Read more
[ad_1] You never assign an initial node. This is the kind of problem that a sheet of paper, a pencil, and two minutes of drawing arrows and boxes should solve, and until you’re fluent in dynamic allocation get used to doing a lot of that. This: if(start==NULL) { p->next=NULL; p->prev=NULL; // NOTE: start is still … Read more
[ad_1] Use this would help: string value = “24.7%”.Trim(); Value = value.Replace(“%”, “”); decimal Value = decimal.Parse(value); string decimalValue = Value.ToString(“0.00″); string actualValue=decimalValue +”%”; [ad_2] solved Converting string to Percent with 2 decimal points [closed]
[ad_1] I am interpreting the following to constitute your question. If writing a speed-intensive app that involves lots of calculations as such, should I rely on the optimization by compiler or on register? If multi-thread, will register cause any problem? First of all, if you are aiming for (and trying to measure) efficiency of a … Read more
[ad_1] You didn’t connect your SqlConnection and SqlCommand. Just define your connection as a second parameter like; SqlCommand CheckExp = new SqlCommand(“SELECT Experience FROM Player WHERE UserID=@uid”, connection); Or you can assing your SqlCommand.Connection property like; CheckExp.Connection = connection; 4 [ad_2] solved ExecuteReader: Connection property has not been initialized. Browser Game [closed]
[ad_1] Because sometimes you cannot look things up on the web. Imagine a sales management app that calculates the discount on a sale. You cannot google that to find the answer. But if you write the app and it returns a discount of 10,000,000$ on an order of 100$ then that’s probably wrong. What he … Read more
[ad_1] This is an X-Y problem. I really doubt you want to flip all the bits in a PNG format file, simply because there are other fields in the file besides the bitmap bits. Also, unless the image is pure black & white, there is more to the color bits than inverting the bits. That … Read more
[ad_1] INN = 9 / 2; will assign 4.0 to INN. Replace it with INN = 9.0 / 2.0; to assign 4.5. Explanation: Because both 9 and 2 are integers, 9 / 2 always results in an integer division, the result of which is an integer too. Thus the result must be rounded, and is … Read more
[ad_1] Age::~Age() is a destructor. It does the exact opposite work of a constructor, that is it destroys the object when its scope is over.
