[ad_1] It creates a constant value named RADIX, which is the radix value for the non-standard type Doub. A radix for a floating-point type is the base of the exponent of its representation (usually 2, but since we don’t know what Doub is, it could also be a custom numeric class which uses a different … Read more
[ad_1] You can capture each value and use the MatchEvaluator to process the groups. string inputString = “[sex:he|she] took the dog with [sex:him|her]”; string result = Regex.Replace(inputString, @”\[(?<name>[^:]+):(?<value1>[^\|]+)\|(?<value2>[^\]]+)\]”, Evaluator); And the evaluator could replace any group with the appropriate response: private string Evaluator(Match match) { if (match.Groups[“name”].Value == “sex”) { if (m_IsMale) { return match.Groups[“value1”].Value; … Read more
[ad_1] New code that works: #include <stdio.h> #include <conio.h> #include <string.h> #include <stdlib.h> #include <time.h> int main() { int i,j=0,code,amt, key,lines=0; int id[100],stock[100],k=0; char name[100][20],product[100]; float price[100],sum; float total=0; char ipname[100][20]; int quantity[100], ch; float ipprice[100]; float ipsub[100]; FILE*fp1; fp1=fopen(“Fruit.txt”,”r”); if(fp1==NULL) { printf(“ERROR in opening file\n”); return 1; } else { while((ch=getc(fp1))!=EOF) { if(ch==’\n’) lines++; … Read more
[ad_1] &c – Is the address of c. foo returns a pointer to this local variable – c. This is bad and should not be done – as c will be out of scope – hence its address will be invalid [ad_2] solved what does int* foo (int a) return in c++ [closed]
[ad_1] I know it’s tagged c, but since you spammed it in Lounge<C++>, let me humor you with C++: Live On Coliru #include <algorithm> #include <functional> #include <atomic> #include <fstream> #include <iostream> #include <list> #include <mutex> #include <sstream> #include <string> #include <thread> #include <vector> // not thread-aware: struct Bank { struct Account { int id; … Read more
[ad_1] The line Student =Console.ReadLine(); //where I am getting an error fails because Console.ReadLine() returns a string, but you are attempting to assign it to a variable of type Student (the variable is confusingly also called Student). There is no way for the compiler to convert a string to the type Student. It looks like … Read more
[ad_1] void Bresenham(int x1,int y1, int x2, int y2, colour) ^ you forgot the type here It should be void Bresenham(int x1,int y1, int x2, int y2, int colour) ( But you are not even using this function in your code ) You should also use int main() over void main() int main() { // … Read more
[ad_1] There is no such thing as global variables in C#. This will do the trick for you. You could also try the static class with static members solution to simulate something like global variables, but that still won’t be a global variable. Try this (you’re using an attribute in the class in this solution, … Read more
[ad_1] Expression 1 – int a; int* ap = &a; Ans : This is an int pointer which will stay on the stack. Expression 2 – int a; int*ap = new a; **// syntax error** Ans: new will allocate memory in heap and this needs manual cleanup (using delete), whereas in Expression 1 it will … Read more
[ad_1] You should have scanf(“%d”,&ch); not scanf(“%d”,ch); Because the result of scanf gets stored in the variable named ch. [ad_2] solved Why does this C function not return an integer value?
[ad_1] According to this topic in DevExpress Support Center: It is not possible to render HTML content in the XRLabel control. To accomplish this task, you can use the XRRichText control and bind the HTML property of this control to the corresponding property in your DataSource. 4 [ad_2] solved Labelcontrol In Devexpress [closed]
[ad_1] This is not a C program, it is a C++ program. Rename your file to array.cpp and/or use g++ instead of gcc, and no, there is no such thing as iostream in C. The first non-C part of your program is using namespace std; there is no namespaces in C. the second part is … Read more
[ad_1] Since the task is to set a certain pin as output, the first thing you need to do is to check the board schematics to find out which microcontroller port and pin that “pin 12” corresponds to. Microcontroller ports often have a 1 letter name such as PORTA, PORTB etc. This is also the … Read more
[ad_1] *pointer nominally requires a fetch from memory, and that is generally the most expensive of the operations shown in your code. If we assume your code is compiled directly to the obvious assembly corresponding to the operations as they are described in C’s abstract machine, with no optimization, modern CPUs for desktop computers are … Read more
[ad_1] I solved this problem by using the Dispatcher: private void grid_SizeChanged(object sender, SizeChangedEventArgs e) { //text.Text = grid.Width.ToString(); Dispatcher.BeginInvoke(new Action(() => text.Text = grid.Width.ToString())); } Thank you all for “help” and negative rating. [ad_2] solved .NET bug. How to fix?
