C++ :: Iterative Loop Repeats More Times Than Expected
Nov 28, 2014
I tried my best but I can't figure out the problem. At the last part of "createArray", I output the final array created. I mean it to repeat once but then it repeat more times than I expect. createArray is an iterative function. If it repeats 3 times, than at last the array created which fulfil the criterion would be printed out 3+1 times.
I am trying to create an array with 3 numbers 5 times, resulting in a 2D array. The 3 numbers in a array are picked from 0 - 5. I enter createArray(5,3,5). Then these 5 arrays are compared with each other to see if there are repetitions. If there are, the whole process begins again, 5 arrays with 3 numbers each will be picked again and compared with each other. If there are no repetitions at last, there 5 arrays would be printed out.
void deleteArray(int** array){
delete[] array;
}
int** createArray(int simu_times, int randomrun,int numberofrun){
vector<Int_t>fChosenRun;
int** Array = new int*[simu_times];
This first Dowhile loop is saying "expected unqualified-id" at the do and while parts. What does that mean
do { do { do { std::cout << "Give me a test result or grade from 0 to 100 for class"<< 1 << std::endl; std::cin >> mathaverage[mathtestcount]; loopresult=1;
#include <stdio.h> #include <math.h> main() { int n; int k; int j; //gets user input for length of string printf("Enter the value of n:"); scanf("%d", &n);
[code]......
When I compile my code I get an error saying that I need declaration specifiers in my is_prime subroutine in the for loop.
I have been trying to make a program that asks for username and password, and if it is wrong it will loop back to the top. But i only want it to loop a set number of times, how can i do this? This is my code so far
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 trouble getting my loop to work correctly. If I iterate the for loop once it works as expected and displays proper output. When I try to iterate two times or more the program gets stuck in an infinite loop.
The function uses a "for" loop to print the given character the number of times specified by the integer.
How can I make a for loop to do that?
So.. my code looks like this:
// cpp : Defines the entry point for the console application // #include "stdafx.h" #include <iostream> using namespace std; void printMyInteger(int myInteger, char myChar) {
[Code] ....
So.. here is my error:

What I'm trying to do is to have the program pick random people for different jobs. The user enters the number of people, then, enters both jobs and the people's names. I need the program to pick random people, but randomly pick again if the person has already been picked, so, no repeats. I have the program picking random people, but I can't get it to not pick the person again. I'll run it and there will be no errors, but it's almost like Xcode completely bi-passes the for/if to check if it's picked the person already.
Below is the code.
#include <iostream> #include <math.h> using namespace std; int main() { int runagain=0, correctnames=0, versiondesciosion=0, correctjobs=0;//vars that make descisions for running again rerun:
[Code] ....
Dont look at the "fun" version for the switch statement. It's not ready yet, I'm just having trouble with the random thing.
I am writing for loop with a switch so that scores can be inputted in by a judge. The issue that I am running into is that I will put out an the text then the test happens and the code puts out the switch statement 5 times with random number. Here is what I have written.
Code: int main() { int diver; int option; int Judge; cout << "Enter Divers Name:";
I use this algorithm for my "crappy" physic engine, so the point of this algorithm is to get the sum of mass below an object. get_below( id ) function can get the ids of what object is below them.
But before I need ids of the object below them to apply impulse, force, and some other physic stuff.
One object doesn't neccesarrly rest on top of one object, it can rest on 2 object or more.
when I look at it, it resemble a tree, maybe it's not. I just don't really know very much about tree algorithm
I cannot optimize a recursive code so I think, I better turn this into an iterative but I cannot seem to find a way to do that
I'm writing the function as described in the title but it isn't quite working. It works as long as the value passed is less than the parent (going left) but when the value should be placed to the right, it doesn't actually insert the node.
Is there any way to programatically find if the given code is taking recursive approach or iterative apporaoch using concept of files in C programming.
#include <iostream> int ival1 int ival2=1 int summe /* run this program using the console pauser or add your own getch, system("pause") or input loop */ int main() {
I keep getting an error here and cant quite figure out why,
Code: else if (mainMenu == 3){ cout << "Please make a selection" << endl << " 1) Withdraw from account" << endl << " 3) Back to main menu" << endl; cin >> withdrawMenu;
I wrote a program, that generates 20 random integers, and stores them in an array. Then I decided, to build more functions to it, i.e why not have it to display the lowest integer of an array. I created my function,
Code: int minValue( int field[ ] )
and got my code in side, which (technically) works. In my main() function I'm calling
Code: printf( "The smallest value of an array is: %d ", minValue( field[] ) );
and I'm getting an error trying to compile it.
Code: randomArray.c:62:74: error: expected expression before ']' token printf( "The smallest value of an array is: %d ", minValue( field[] ) );
After compiling it is giving error as : foo.cpp: In function ‘int Foo_max(Foo*)’: foo.cpp:26:37: error: expected primary-expression before ‘int’ foo.cpp:26:46: error: expected primary-expression before ‘int’
I have a template class (A) that derives from a either a base class that has a member (_A1.m) or not (_A0), based upon it's template parameter. class (A) has a member function (fn) returns the value of (m) as it understands what (m) is.
However, this gives different results compared with a non-template class in a similar scenario. I'm expecting that if derived from _A1, that m should be taken from the base class scope and if derived from _A0, it should be taken from the global one.
Here is the code for your amusement:
int m = 5; class _A0 { public: _A0(int) {
[Code] ....
This compiled using g++ 4.5.3 and 4.6.3 with the same results: Global value of m is: 5 B0 class has no internal m member. Object resolves m internally with value 5 B1 class has internal m member. Object resolves m internally with value 3 A<_A0> class has no internal m member. Object resolves m internally with value 5 A<_A1> class has internal m member. Object resolves m internally with value 5
#pragma once #include <iostream> class CBox // Derived class { public: // Constructor explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv){}
[Code] .....
Before the program ends, at return 0;
I would expect the CBox destructor to be called 3 times but it is being called 6 times? Why? Also in this code:
#pragma once #include <iostream> class CBox // Derived class { public: // Constructor explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv){}
[Code] .....
Why is the destructor called 3 times? When have you really destroyed a CBox? Doesnt emplace only create it and store it, then thats it?

For pushback:
void push_back(value_type&& _Val) {// insert by moving into element at end if (_Inside(_STD addressof(_Val))) {// push back an element size_type _Idx = _STD addressof(_Val) - this->_Myfirst;
I'm trying to perform a simple input operation, and check to make sure that whatever the user input is a valid input (is within data type bounds, is correct data type...). But when I get to ignoring the input, I keep getting an error.
unsigned short num; while (true) { std::cin >> num; if (std::cin.fail()) { num = 1;
