I create a loop that would repeat itself many times a second? Trying to do extremely basic graphics with a grid and system("cls") every time I run a command, but it still looks very jumpy. I realize system calls are evil. Any way to get rid of this too.
I'm having a little trouble writing program that on remove all repeat characters and leave only the non repeated characters. This is want I have so far.
I created a very basic program which contains a vector (my vector) that holds 0, 1 and 1. This program compares each element in the vector. If the element after the one currently being compared is equal to it, it outputs "repeat found!" Now this all works perfectly, but my next step was to erase the repeated one. Everything was working up until the delete step. I get a weird error that says "vector iterator not dereferencable" .
// vector::begin/end #include <iostream> #include <vector> using namespace std; int main () { vector<int> myvector;
I have a method that changes a canvas color after set intervals, e.g. start timer, 5 seconds green, 3 seconds red, then stop. This functionality is provided in the interval method. The problem I'm trying to achieve is getting this sequence to repeat for a set number of iterations.
I tried to solve this by setting up a counter after the timer is stopped but the code keeps repeating indefinitely by starting and stopping over and over instead of the max of 6 iterations I had set. In debugging the problem, I watched the value of 'i' and when the 'if' statement is set to false. The 'if' statement gets set to false after 7 iteration as expected but the start(); keeps getting called.
void myTimer_Tick(object sender, EventArgs e) { //Assign text box string value to a time span variable. TimeSpan workTm = TimeSpan.ParseExact(wrkString, @"hh : mm : ss : fff", CultureInfo.InvariantCulture); TimeSpan restTm = TimeSpan.ParseExact(rstString, @"hh : mm : ss : fff", CultureInfo.InvariantCulture);
// update the textblock on the display // with hh, mm, ss, ms ms = myStopwatch.ElapsedMilliseconds;
Here is my code for a simple game. paste it and try it.
#include <iostream> #include <string> #include <ctime> #include <cstdlib> using namespace std; int main (void) { stringg[4],
[code]...
What they do (enter 4 actions)?
"; for (int ai = 0; ai < 4; ai++) getline(cin, a[ai]); cout << "
Where is happening (enter 4 locations)?
"; for (int li = 0; li < 4; li++) getline(cin, l[li]); for (int c = 0; c < 4; c++) cout << g[rand() % 4] << " and " << b[rand() % 4] << " are " << a[rand() % 4] << " from a " << l[rand() % 4] << endl; return (0); }
At the end in the 4 lines some of the names, actions and locations repeat. How do I make them to not repeat and use every name that you will enter? do I need random_shuffle? How can I integrate it in my code?
I have an array matrix called tmat,,and i know that in every row of tmax there are values which repeat two times...and am writing a code to extract the values WHICH DOES NOT REPEAT into another matrix called tcopy...the codes compiles fine...and it writes nicely to file...but without the desired result...
One last question...how can i get the array tcopy written to file in the form 5x3...and not all the figures in line one after the other? i mean i wish to see the matrix like a matrix on file..not like a list of numbers....
Code: #include <iostream> #include <fstream> #include <vector> using namespace std; const int R = 5; const int C = 5;
Repeat the vowel Problem 3 (0 / 0)Write a program that will repeat k times each single occurrence of a vowel in the input file "sp.txt" to a new file "output.txt". The first line of the input file contains only the parameter k. The first line (containing the parameter k) should not to be written in the output file.
I wrote the code but i cant figure out something. i read the file, i found the vowels but then i cant print them.
Code: #include <stdio.h>#include <string.h> #include <ctype.h> #define MAX 100 int checkvowel(char c)
Write a program which is used to calculate GPA based on the grades from different courses Input by the user. User should be able to enter as many course unless they choose to quit. Once the user has completed entering the data, the program should be able to provide a feedback on the GPA. Where A=4, B=3, C=2, D=1.
We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.
I have tried to submit this topic before but i didn't submit my whole code and it was removed. So here it is. All I am trying to do is load form2 from form1 then back to form1 from form2 for a certain number of times the get out of the loop. I am new to C-Sharp and it seems as though I cant seem to figure out a way to do this.
Here is form1 and form2 code. I have commented out a few things I have tried.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data;
I already made a nested for loop into a while loop (below this) and now I'm trying to make the outer for loop into a do while loop, but it's not working.
#include <iostream> using namespace std; int main () { int len; int j; int i;
[Code]....
And I can't make this code do the same thing. It stops after one loop, instead of continuing to the end. Why won't the loops continue?
#include <iostream> using namespace std; int main(){ int len; cout << "Enter a number: ";
I for the life of me can't get my logic straight. I have 2 lists, 1 a list of text, and the other a list of int.
Here's my main list: List<string> ListNeedToADD = ListOfSPSExt.Except(ListOfReportExt).ToList(); Here's my second list:IEnumerable<int> result2 = Enumerable.Range(1, Convert.ToInt32(myValue)).Except(hostList);
I need to loop through my main list, ListNeedToADD, and for each item in that list, grab 1 value from the 2nd list and send those 2 items to a method. Something like this:
The problem with doing it the way I am above is it loops through ALL the items for each myString.
For my method, it needs to look like this: insertReportLimits(attribTable, "34257", 22, con); then it would move on to the next: insertReportLimits(attribTable, "34854", 27, con); etc etc.
I can't get out of my loop to fill the array. This array should stop and print after 10 inputs. but it keeps asking for input.
This is what my code is supposed to do. Use 0 as sentinel for an array. Only positive ints will be entered into the array. A negative int should result in an error message, then input will continue. The numbers will be inserted into the array in ascending order. Do not insert them then sort the array.
#include <iostream> #include <cmath> using namespace std; const int arraySize =10;
I am using a for loop to count down from 10 to 0 it's working to count down from 10 to 1 but when the program cames to the 0 then the program freezes by any reason.
Code: #include <iostream> using namespace std; int main() { int number[2]; cout << "Enter number: "; cin >> number[0]; if (number[0] == 1)
What I need to do to get rid of the infinite loop?
Code: do { printf("Enter the number of tests:"); scanf("%d", &test); if (test< 0 || test> 4) printf("Wrong number. Please try again! "); } while (test< 0 || test>4);
