Please explain me this code mainly that void remove() ...In void remove there is for loop so how it remove only first element wh
#include <iostream> using namespace std; class Queue { int size; int* queue; public: Queue() { size=0; queue = new int[100]; } 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; } //your code goes here void add(int x){ size+=1; queue[size-1]=x; } }; int main() { Queue q; q.add(42); q.add(2); q.add(8); q.add(1); q.print(); q.remove(); q.add(128); q.print(); q.remove(); q.remove(); q.print(); return 0; }
