#Compiler giving the error?

We can only help if you send the error message
lime valve
warm sinew
Please send the error as text
not the worst photo known to man 😉
It's also better to look at the actual errors from the compiler, not what vscode shows
lime valve
MyStack<char> operatorStack(length);
This line giving the error
warm sinew
Show the definition of MyStack
lime valve
#include "Stack.h"
template<class T>
class MyStack :public Stack<T>
{
public:
void Push(T element);
T Pop();
T top();
bool isEmpty();
~MyStack();
};
template<class T>
MyStack<T>::~MyStack() {
delete[] stackArray;
}
template<class T>
void MyStack<T>::Push(T element) {
if (stackTop == stackSize - 1) {
cout << "Stack Overflow" << endl;
return;
}
stackArray[++stackTop] = element;
}
template<class T>
T MyStack<T>::Pop() {
if (stackTop == -1) {
cout << "Stack Underflow" << endl;
return T();
}
return stackArray[stackTop--];
}
template<class T>
T MyStack<T>::top() {
if (stackTop == -1) {
cout << "Stack is Empty" << endl;
return T();
}
return stackArray[stackTop];
}
template<class T>
bool MyStack<T>::isEmpty() {
return stackTop == -1;
}```no instance of constructor "MyStack<T>::MyStack [with T=char]" matches the argument listC/C++(289)
infixToPostfix.h(31, 33): argument types are: (int) this is error
warm sinew
MyStack seems to have no constructor that would take an int
But what's the definition of Stack
lime valve
#include<iostream>
using namespace std;
template<class T>
class Stack {
protected:
T* stackArray;
int stackTop;
int stackSize;
public:
Stack(int size);
virtual ~Stack()=0;
virtual void Push(T element)=0;
virtual T Pop()=0;
virtual T top()=0;
virtual bool isEmpty()=0;
};
template<class T>
Stack<T>::Stack(int size) {
stackArray = new T[size];
stackTop = -1;
stackSize = size;
}```I send you a full program
#include "MyStack.h"
template<class T>
class CharStack : public Stack<T> {
public:
CharStack(int size) : Stack<T>(size) {}
~CharStack() {}
void Push(T element) {
Stack<T>::Push(element);
}
T Pop() {
return Stack<T>::Pop();
}
};

Tell me my mistakes in this code
lime valve
Your code doesn't compile for me for a lot of other reasons
Compiler giving compile time error
Only one line
Line is MyStack<char> operatorStack(length);
