[ad_1] Why the arr[1] value is changing when changing the value of arr1[1]? This is your first question, but keep it now after answering the second. and similarly why it is changing when ((int[])o)[1] = 1000; This is your second question. Answer is by seeing what is the initial value of o variable. Object o … Read more
[ad_1] 1) You need a semicolon and the end of your prototype: float xc(float frequency, float capacitance); 2) Variable declarations don’t have “()” float f; float c; 3) arguments are separated by commas: capreac = xc(f, c); 4) argument names should match variable names: float xc(float frequency, float capacitance); { float answer; answer = (1.0/(2.0*pi*capacitance*frequency)); … Read more
[ad_1] Can we declare an interface class by making all the methods abstract using the keyword ‘abstract’ in a class in C++? [duplicate] [ad_2] solved Can we declare an interface class by making all the methods abstract using the keyword ‘abstract’ in a class in C++? [duplicate]
[ad_1] //Here First you need to upload file on application server then convert into File Stream. string auditReportUploadDocLocation = ConfigurationManager.AppSettings[“AuditReportUploadDocLocation”].ToString(); string filelocation = Path.Combine(Server.MapPath(auditReportUploadDocLocation), fuUploadDoc.FileName); fuUploadDoc.PostedFile.SaveAs(filelocation); fileName = Path.GetFileName(fuUploadDoc.PostedFile.FileName); using (FileStream fs = new FileStream(filelocation, FileMode.Open, FileAccess.Read)) { objAudAuditReportMaster = objAudAuditReportBAL.UploadAuditReportDoc(fileName, fs, Session[“AudLoginID”].ToString(), audProcessName); } //Delete the file from application server. if (File.Exists(filelocation)) File.Delete(filelocation); //After … Read more
[ad_1] is there a way to get the sign of a number (any kind, not just integer) Not for any number type, no. For an integer, you can test the most significant bit: if it’s 1, the number is negative. You could theoretically do the same with a floating point number, but bitwise operators don’t … Read more

[ad_1] Since sqlfunctions inherits from QObject, you can pass a sqlfunctions* to a function expecting a QObject*: frame->addToJavaScriptWindowObject(objJavascriptName, &obj); 1 [ad_2] solved Qt: Expose any C++ object to Javascript
[ad_1] Right shift assignment operator: num >>= 1 is the same as num = num >> 1 http://msdn.microsoft.com/en-US/library/23as4533(v=vs.80).aspx [ad_2] solved What does the “>>=” operator mean in C#?
[ad_1] The general case depends on whether the threads are wholly independent of each other. If you go multi-threaded, you must ensure that any shared resource is accessed appropriate protection. The code shown has a shared resource in the use of srand() and rand(). You will get different results in a multi-threaded process compared with … Read more
[ad_1] Learning Objective-C is an absolute minimum for iOS development. You really will be needing a Mac to develop on, but if you want to learn Objective-C before picking up a Mac then install a copy of Linux; gcc will compile Objective-C. Once you have a Mac you’ll have free access to XCode, which includes … Read more
[ad_1] I rewritten your code, removed global variables, changed formatting for easier reading, rename some variables to more explain for what they are and add function prototypes. Hope this will help you a little. There are still lot of places which should be changed, but i want to keep as close to your original code … Read more
[ad_1] A vector is a templated class that can store anything that you ask it to store when you defined it. For example: vector<int> // vector that will store any number of integers vector<double> // vector of double precision floating points vector<string> // vector of strings vector<T> // vector of Ts, being understood that T … Read more
[ad_1] parse the string into components; possibly by position, possibly with Parse, possibly with regex decide what rules you want for each output use it For example: static string SimplifyTime(string value) { var match = Regex.Match(value, “([0-9]{2})hr:([0-9]{2})min:([0-9]{2})sec”); if (!match.Success) return value; int val = int.Parse(match.Groups[1].Value, CultureInfo.InvariantCulture); if (val > 0) return val + “hr Ago”; … Read more
[ad_1] If I understand the question correctly, you could use the function in the reference as is. oldArray = GrowArray(oldArray, oldCount, newCount); It could be modified to use a local temporary and then std::swap, but this would depend a lot on the context in which it is used. 1 [ad_2] solved Reallocating an array that … Read more
[ad_1] Assembled from comments (because it was easier than finding a dupe): In modern C (that is, C from this century), all functions need a return type and the only two legal prototypes for main are: int main(void) int main(int argc, char* argv[]) An obsolescent way to write the first is int main(). On Max … Read more
