Answer to Question #213951 in C++ for Maryam

Question

Create a class template for a class named GeneralStackthat holds

• A single data member as an array named stack of size 50 to store certain elements.
• Three member functions i.e. push(type) to add elements in the Stack, pop() to remove elements from the stack, and currentStatus() to check whether the array is filled or not. (A filled array is an array that has non-zero value at all of its indexes).

In the main() function, create three objects with different data types of class General Stack and test the functionality of member functions for various values of data members for these objects.

Answer 1

#include <iostream>
using namespace std;
template<typename type>
class GeneralStack{
    type stack[50];
    int size;
    public:
    GeneralStack(){
        for(int i = 0; i < 50; i++) stack[i] = (type) 0;
        size = 0;
    }
    void push(type data){
        if(size == 50){
            return;
        }
        else stack[size++] = data;
    }
    void pop(){
        if(size == 0) return;
        else{
            cout<<stack[--size]<<" ";
            stack[size] = (type)0;
        }
    }
    bool currentStatus(){
        if(size == 50) return true;
        return false;
    }
};
int main(){
    GeneralStack<int> integers;
    GeneralStack<float> floats;
    GeneralStack<char> chars;


    for(int i = 0; i < 52; i++){
        integers.push(i);
        floats.push(i);
        chars.push(i + 65);
    }
    if(integers.currentStatus()) cout<<"\nArray is full!\n";
    floats.pop();


    cout<<endl;
    for(int i = 0; i < 45; i++){
        integers.pop();
    }


    if(!chars.currentStatus()) cout<<"\nArray is NOT full";
    cout<<endl;
    chars.pop();
    return 0;
}
