Here I am sending code, screens of code and output. Please refer the screens. If any queries or question comment below. Thank you.

Cpp Code:

#include <iostream>
using namespace std;

int stack[5], top = -1; //declaring array size with 5.

int main()
{
int val; //declaring variable.

cout<<"Enter values to push: "; //prompting the user to enter values to push.

/*push the values in to the stack.*/
for(int i=0; i<5; i++)
{
cin>>val; //reading the values
stack[++top] = val; //push in to the stack.
}

/*displaying peek and popping the stack.*/
for(int i=4; i>=0; i--)
{
cout<<stack[top]<<"\n"; //displaying peek element.

top--; //popping the stack.
}
return 0;
}

output:
