Problem with my Queue coding >> if else and while loop

[lukelee1987]

anyone can help to solve this ?

#include<queue>
#include<iostream>
#include<ctime>
using namespace std;

void wait (int seconds) //timer
{
clock_t ewait;
ewait = clock() + seconds * CLOCKS_PER_SEC;
while (clock() < ewait ) {}
}
/*
class Counter{
int count;
int waittime;
public:
Counter() : count(0) {}
Counter(int i) : count(waittime) {}
int operator()(){
return count++;
}
};*/


int main()
{
queue <int> Q;
queue <int> waitID;
int temp1, temp2;

int number, waittime, arrivetime, temp;
for (int i =0; i<5 ; i++)
{
number = 1+ rand() %10; // generate random ID
arrivetime = 1+ rand() %3; // generate random arriving time
waittime = 1 + rand() %16; // generate random serving time
cout <<"Job ID - "<< number << " ----- " << "Service time: " << waittime << "sec" <<endl;
wait(arrivetime);
Q.push(number);
waitID.push(waittime);
}

while (!Q.empty())
{
cout<<"Server 1 serving "<< Q.front() << " serving.. wait .."<< waitID.front() <<endl;

do
{
waitID.front()--;
cout<<"Sec left:"<<waitID.front()<<endl;
wait(1);
}

while(waitID.front()>1);
{
Q.pop();
waitID.pop();
cout <<" Job done "<<endl;
}
/*
while (waitID.front() == 7)
{
temp1 = Q.front(); // store into temp storage
temp2 = waitID.front();
Q.push(temp1);// push temp element to the queue
waitID.front()--;
waitID.push(temp2);

cout << "requeue" << temp1<<endl;
}
*/
}

if (waittime >= 7)
{
//Counter waitID.front();
//Counter();
temp1 = Q.front(); // store into temp storage
temp2 = waitID.front();
Q.push(temp1);// push temp element to the queue
waitID.front()--;
waitID.push(temp2);

cout << "requeue" << temp1 <<endl;
}
else if
{

}

cout << "No more queue" <<endl;

}

What do you want solved? If all you want to do is fix the errors include cstdlib so you can use rand and delete

else if
{

}

which starts at line 86. Also edit your post and add code tags.

[ne555]

while(condition);
{
    statement1;
    statement2;
}

Please don't do that, it's confusing.


I know it's commented but, what is this supposed to do?
Counter(int i) : count(waittime) {}

That's an constructor with an initializer list. However it seems odd in that it is assigning waittime (an uninitialized variable) to count, ignoring the passed value of i.
