Program implements array as a stack.
#include #include #define MAX 10 struct stack { int arr[MAX] ; int top ; } ; void initstack ( struct stack * ) ; void push ( struct stack *, int item ) ; int pop ( struct stack * ) ; void main( ) { struct stack s ; int i ; clrscr( ) ; initstack ( &s ) ; push ( &s, 11 ) ; push ( &s, 23 ) ; push ( &s, -8 ) ; push ( &s, 16 ) ; push ( &s, 27 ) ; push ( &s, 14 ) ; push ( &s, 20 ) ; push ( &s, 39 ) ; push ( &s, 2 ) ; push ( &s, 15 ) ; push ( &s, 7 ) ; i = pop ( &s ) ; printf ( "\n\nItem popped: %d", i ) ; i = pop ( &s ) ; printf ( "\nItem popped: %d", i ) ; i = pop ( &s ) ; printf ( "\nItem popped: %d", i ) ; i = pop ( &s ) ; printf ( "\nItem popped: %d", i ) ; i = pop ( &s ) ; printf ( "\nItem popped: %d", i ) ; getch( ) ; } /* intializes the stack */ void initstack ( struct stack *s ) { s -> top = -1 ; } /* adds an element to the stack */ voi...
