Solved of this problem : #include
<iostream> using
namespace std; int
stack[100], k=100, high=-1; void
push(int value) { if(high>=k-1) cout<<"Stack
Overflow"<<endl; else { high++; stack[high]=value; } } void pop()
{ if(high<=-1) cout<<"Stack
Underflow"<<endl; else { cout<<"The popped element is
:"<<" "<< stack[high]<<endl; high--; } } void
display() { if(high>=0) { cout<<"Your stack elements
are:"; for(int i=high; i>=0; i--) cout<<stack[i]<<"
"; cout<<endl; } else cout<<"Your stack is
empty"<<endl; } int main()
{ int userInput, value; cout<<"1) Push in
stack"<<endl; cout<<"2) Pop from
stack"<<endl; cout<<"3) Display
stack"<<endl; cout<<"4)
Exit"<<endl; do { cout<<"Enter your choice:
"<<" "; cin>>userInput; switch(userInput) { case 1: { cout<<"Enter your
value for pushed:"<<" "; cin>>value; push(value); break; } case 2: { pop(); break; } case 3: { display(); break; } case 4: {
cout<<"Exit"<<endl; break; } default: { cout<<"Invalid
Choice"<<endl; } } }while(userInput!=4); return 0; } Console output of this problem is:
