 Write a C ++ Program for creating a queue using array with 10 20 30 40 50 elements and print its elements.Code - 

#include <iostream>

using namespace std;

int queue [100], n=100, front =-1, rear= -1;

void Insert(int num){

                int val;

                if (rear == n-1)

                cout<<"Queue Overflow"<<endl;

                else{

                                if (front== -1)

                                front = 0;

                                rear++;

                                queue[rear] = num;

                }

}

void Display(){

                if (front ==  -1)

                cout <<"Queue is empty"<<endl;

                else{

                                cout <<"Queue element are :";

                                for (int i = front; i<= rear; i++)

                                cout<< queue[i]<<" ";

                                cout <<endl;

                }

}

int main(){

                Insert(10);

                Insert(20);

                Insert(30);

                Insert(40);
