Write a $C++$ program to implement stack using array

ALGORITHM:

Define Global Constants and Variables:

Declare a global constant MAX to define the maximum size of the stack.

Declare a global array stack$\_$arr to represent the stack.

Initialize a global variable top to $-1$ to represent an empty stack.

Main Function $($main$)$:

Declare a local variable data to store the popped value.

Call push$(1)$ to push the value $1$ onto the stack.

Call push$(2)$ to push the value $2$ onto the stack.

Call push$(3)$ to push the value $3$ onto the stack.

Call push$(4)$ to push the value $4$ onto the stack.Call pop$()$ to pop a value from the stack and store it in the data variable.

Call printo to print the elements of the stack.

Return $0$ to indicate successful program execution.

Pop Function $($pop$)$:

Check if the top is $-1,$ indicating stack underlow.

Declare a local variable value to store the popped value.

Assign the value at the top of the stack to value.

Decrement the top to remove the top element from the stack.

Return the popped value.Print Function $($print$)$:

Declare a local variable i$.$

Check if the top is $-1,$ indicating stack underflow.

Iterate from the top the bottom of the stack using a for loop:

Print the value at index $i$ of the stack.

End the function.

Push Function $($push$)$:
