Your forgot to ad #include <ctime> srand(time(NULL)) at the start of your program. This will generate a new seed everytime you run your program based on the current time. 1 solved C++ random function return same numbers [duplicate]
Instead of ch = Convert.ToChar(Console.ReadKey()); You should put it as ch = Console.ReadKey().KeyChar; Since ConsoleKeyInfo instance which is returned by Console.ReadKey() can’t be just converted into char 4 solved Throwing an exception at line16 [closed]
Can anyone explain why address operator is returning string and not the address in the following C++ program? [closed] solved Can anyone explain why address operator is returning string and not the address in the following C++ program? [closed]
I won’t attempt to wade through the whole paper, but I can explain the syntax and make some educated guesses about what’s going on. #define IX(i,j) ((i)+(N+2)*(j)) This looks to me like they’re transforming two-dimensional coordinates i,j into a one-dimensional array index. j is the row number and i is the column number, which jibes … Read more
That is a shortcut for: cv::Mat_<double> myMat_(3, 3); myMat_.at(0, 0) = 1.0; myMat_.at(0, 1) = 2.0; myMat_.at(0, 2) = 3.0; myMat_.at(1, 0) = 4.0; myMat_.at(1, 1) = 5.0; myMat_.at(1, 2) = 6.0; myMat_.at(2, 0) = 7.0; myMat_.at(2, 1) = 8.0; myMat_.at(2, 2) = 9.0; The << and the , operators are overloaded to implement that … Read more
First of all set the Label lblDraw as In frmStats form public string strNumber { get { return lblDraw.Text; } set { lblDraw.Text = value; } } Form1 if (winner != 0) this.Text = String.Format(“Player {0} Wins!”, winner); else if (winner == 0 && turnCounter == 9) { this.Text = “Draw!”; //this is where i … Read more
Here is the problem, void readStructs(tMystruct *theVar) { scanf(“%d”,theVar.id); //<——problem scanf(“%f”,theVar.length); //<——problem } You should access Structure pointer member using -> operator and also you’re missing & that will eventually cause a segmentation fault. Here is the modified code, void readStructs(tMystruct *theVar) { scanf(“%d”,&theVar->id); scanf(“%f”,&theVar->length); } solved How to pass structure by reference in C?
for(i=0;i<lim-1&&(c=getchar())!=EOF&&c!=’\n’;i++) why do we use c!=’\n’ We use c!=’\n’ to stop scanning input characters when user enters a \n (newline) character or in other words,when user hits the enter key. why have we used s[i]=’\0′ in and i++; statement in if(c==’\n’) condition i++ is used to increase the index value of the array/string for one … Read more
int (*f(float (*)(long),char *))(double) f is a function that has 2 parameters of type float (*)(long), << pointer to function long=>float char * << string and returns (int)(*)(double) << a pointer to a function double=>int 2 solved How to create an example for the complex statement? [closed]
(int)(float)(char) i; is not a definition of i. It merely is using the value for nothing. #include <stdio.h> double i; int main(void) { i; // use i for nothing (int)i; // convert the value of i to integer, than use that value for nothing (int)(float)i; // convert to float, then to int, then use for … Read more

You can use events to make your scripts “communicate” independently. First you need the gameevents. Make sure you have the script on a gameobject in your scene: using System; using System.Collections; using System.Collections.Generic; using UnityEngine; public class GameEvents : MonoBehaviour { public static GameEvents gameEvents; private void Awake() { gameEvents = this; } public event … Read more
Although this is C program. But prime number logic will be same for C and Java both Prime number Each natural number that is divisible only by 1 and itself is prime. Also, 2 is the first prime number. For example, we want to test that number 100 is a prime number or not. we … Read more
It can be done without recursion. var s = “A,B,C|1,2|a|u,v,w”; var u = s.Split(‘|’).Select(v => v.Split(‘,’)).ToList(); var buffer = new List<string>(); buffer.Add(“COMMAND “); while (u.Count > 0) { var t = from a in buffer from b in u.First() select a + ‘ ‘ + b; buffer = t.ToList(); u.RemoveAt(0); } The buffer list will … Read more
It crashes because you are accessing argv[1] which would hold a command line argument (other than the program’s name) if there was one. You should check whether argc is greater than 1. Why greater than 1? Because the first command line argument is the name of the program itself. So argc is always greater than … Read more
