It's time to update your Queue management system. The previous version supports only integer numbers and we need to support more

Question

I wriiten a code but due to single eror my code is not compiling showing eror can anyone help me

Answer 1

#include <iostream>
using namespace std;

template <class T>
class Queue {
int size;
T* queue;

public:
Queue() {
size = 0;
queue = new T[100];
}
void add(T data) {
queue[size] = data;
size++;
}
void remove() {
if (size == 0) {
cout << "Queue is empty"<<endl;
return;
}
else {
for (int i = 0; i < size - 1; i++) {
queue[i] = queue[i + 1];
}
size--;
}
}
void print() {
if (size == 0) {
cout << "Queue is empty"<<endl;
return;
}
for (int i = 0; i < size; i++) {
cout<<queue[i]<<" <- ";
}
cout << endl;
}
Queue operator+(Queue &obj) {
Queue res;
for(int i=0;i<this->size;i++) {
res.add(this->queue[i]);
}
for(int i=0;i<obj.size;i++) {
res.add(obj.queue[i]);
}
return res;
}
};

int main() {
Queue<int> q1;
q1.add(42); q1.add(2); q1.add(8); q1.add(1);
q1.print();

Queue<string> q2;
q2.add("Dave"); q2.add("John"); q2.add("Amy");
q2.print();

return 0;
}

Answer 5

I mean, there's a whole bunch of stuff wrong here..

Declare the class with the class keyword.

template <class T>
class Queue {
...

int main, not T main. The main function does not accept generic types.

When instantiating Queue, use actual types.

Queue<int> q1;
...
Queue<std::string> q2;

Answer 6

Rachita Bhasin You do not need two Queue classes. The whole premise of having templates is that you do not need to create multiple classes for different types. Remove Queue1.

Answer 7

T1 {
T1 size;
T1* queue1;

public:
Queue() {
size = 0;
queue1 = new int[100];
}

void add(String data) {
queue[size] = data;
size++;
}

void remove() {
if (size == 0) {
cout << "Queue is empty"<<endl;
return;
}
else {
for (int i = 0; i < size - 1; i++) {
queue[i] = queue[i + 1];
}
size--;
}
}
void print() {
if (size == 0) {
cout << "Queue is empty"<<endl;
return;
}
for (int i = 0; i < size; i++) {
cout<<queue[i]<<" <- ";
}
cout << endl;
}
Queue operator+(Queue &obj) {
Queue res;
for(int i=0;i<this->size;i++) {
res.add(this->queue[i]);
}
for(int i=0;i<obj.size;i++) {
res.add(obj.queue[i]);
}
return res;
}
};

T main() {
Queue<T> q1;
q1.add(42); q1.add(2); q1.add(8); q1.add(1);
q1.print();

Queue<T1> q2;
q2.add("Dave"); q2.add("John"); q2.add("Amy");
q2.print();

return 0;

class Queue1 {
T size;
T* queue;

public:

size = 0;
queue= new int[100];
}

void add(Strin

Answer 13

int main() {
Queue<int> q1;
q1.add(42); q1.add(2); q1.add(8); q1.add(1);
q1.print();

Queue1<std::String> q2;

q2.print();

return 0;
}

Answer 14

Ok so it means in that queue only I have to create

Answer 15

Is this ok?

Answer 16

int main() {
Queue<int> q1;
q1.add(42); q1.add(2); q1.add(8); q1.add(1);
q1.print();

Queue<std::String> q2;
q2.add("Dave"); q2.add("John"); q2.add("Amy");
q2.print();

return 0;
}
