I'm having troubles with this program I made. Put it simply, it's a basic program using Queues. Whenever I try to input a value, my compiler(Dev C) suddenly stops working. The .exe file crashes and I've no way on how I can execute my program.
Code :
#include<iostream>
using namespace std;
int *queue;
int rear, front, queueSize;
void enqueue();
void dequeue();
void display();

I am trying to enter data to a structure some 8 times, but not able to do so. Here is my code.
Code: #include<stdio.h>
struct _Timer {
unsigned int HH;
unsigned int MM;
}Time[8];
[code]...
But when I enter any data and press enter , the .exe file stops working and not able to enter data.
Just using Find in my source code to look for variables or whatever, works once or twice then just stops - Doesn't find anything even if it's there. If I restart VS it works again, but not for long.

I made some code but after minute or less the sound stops, so I made silly workarround. After 30 clicks I invoke sound->stop(); and then the loop start again, that works, but it's not good, can you give better solution. Here is my code:
Code:
int count = 0;
bool MainWindow::eventFilter(QObject *o, QEvent *e){
if(e->type() == QEvent::KeyPress)

I'm trying to write a C++ program that will allow a user to input a number from the keyboard. Then using a loop, that will perform 10 times, multiply the entered number by the loop counter. Print out the loop counter, the entered number and the product of the loop counter and the entered number. A one-time heading should be displayed before information is printed.
This kinda of what I have so far:
#include <iosteam>

All the programs I have tried to make are not working?
the program is of an address book. the syntax is all fine, and the initial menu of options does show up. but once you punch in the cin, the program just stops.

For my homework I need to create a hash table with a size of 7. I also need to create a queue that holds 3 names maximum for each table position
View 1 Replies View RelatedI have the following code which will find the minimum size queue among a vector of queues and the minimimum size queue will enqueue(push) the int
std::vector<std::queue<int> > q
void enqueue(){
int min_index = 1;
std::size_t size = q.size();
for( i=2; i<size; i++) //accessing loop of queues
if(q[min_index].size() > q[i].size())
min_index = i; // Now q[min_index] is the shortest queue
q[min_index].push(int)
}
Now my another paradigm is to do the dequeue(pop) operation in another function(shown below), bt i need to access all vector of queues declared in enqueue() function. how can i access the loop of queues given in the enqueue() function?
void dequeue(){
//q.pop operation , access all the queues in the loop of queues
}
willq[i].pop(int);
Access all the queues in the enqueue function and does the pop operation?
i have a paradigm where a integer before gets enqueued to a queue, the loop of queues in a vector is searched and integer is enqueued to a queue which has minimum size among the queues. the following code shows the operation.
#include <vector>
#include <queue>
std::vector<std::queue<int> > q
int min_index = 0;
std::size_t size = q.size();
for( i=0; i<size; i++){ //accessing loop of queues
if(q[min_index].size() > q[i].size())
min_index = i; // Now q[min_index] is the shortest queue}
q[min_index].push(int)
next i am trying to extend my paradigm with that the condition the integers should be enqueued to the shortest queue until it becomes maximum size among the queues.
do{
q[min_index].push(int)
} while(q[min_index].size > queue sizes in the vector loop except this queue )
how to search the loop of queues of vector in the while ()
Why my output screen for this program does not want to stay open. It only opens for a split of a second and it's gone. The program is supposed to take numbers from a input file and display and save the manipulation in the output file. Here is the program.

I'm trying to solve the ferry loading problem using two queues. My problem is I can't enter in data after the first set is scanned in, I'm assuming there is a problem with my loop, such that the scan function doesn't get called after one iteration. In the example I marked the data I can't enter. An example correct input would be:
correct input:
1 - can enter data20 4 - can enter data
380 left - can enter data
720 left - can't enter data
1340 right - can't enter data
1040 left - can't enter data
correct output: 3
my incorrect output: 1

I wrote this program to create a list of medical resources and their attributes, a task I have been performing repeatedly lately. I'm still fairly new to C++, so I thought to create a structure "Resource", and then an array of those structures "city[300]". My problem is that the input doesn't seem to be happening: the program runs, but when it prints to screen/writes to the file at the end, all the shows is:
Resource Type:
Name:
Address:
Phone:
Website:
for every resource that was input. All the fields are blank.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
struct Resource {
string typeID;
string name;

As I was testing it, the program suddenly stopped giving an output. Here is the code:

The while loop after int glutton does not work and seems to stop the program. I replaced the "glutton" in the cout with "testing testing" and it still did not work. However, when I commented out the loop, it appeared. Finally, it can't be what's inside the loop, because I commented that out too, and it still didn't work.
I am currently working on a c++ project that will input students and process their grades. I encountered a problem and my code stops executing after the getScores function. Im not sure what the problem is, but im guessing its something within the function and the loops.

//Parameters: None
//Return: testScore
double getScores()

Q.......

I am relatively new to C programming, and I am encountering numerous issues with this program that I cant seem to figure out how to fix.
First, when the user selects the arithmetic game, I keep on getting different incorrect answers from the arithgame function. For example, when I am presented with the question 3+2=_, sometimes the function claims the answer is the first number, 3, and other times the function gives me a multiplication answer, 6. This happens in both the addition and multiplication parts (ie. the multiplication answer will either be the first number or the addition answer).
Additionally, I cant figure out why my guessing game loops forever, rather than letting me guess until I get a correct answer.

I would like to modify attributes like modification/creation dates.The function is correctly working as if I type in "ls -al", the timestamp is correct. But when using my program to read these attributes, it returns the "real" modification/creation date. Here is the function that shows the timestamp :
Code:
time_t t = sb.st_mtime; struct tm tm = *localtime (&t);
char s[32];
strftime (s, sizeof s, "%d/%m/%Y %H:%M:%S", &tm);
printf ("%-14s %s", lecture->d_name, s); And here is the code for modifying the timestamps : Code: void modifyAttributes(char * file, int mtime, int atime)
