Example of structure:
struct item
{
int element;
node_ptr next;
};
typedef node_ptr stack;
stack create(void)
stack s;
s=(stack)malloc(sizeof(struct item));
s->next=NULL;
return s;
}
void push(stack s,int a)
node_ptr temp;
temp=(node_ptr)malloc(sizeof(struct item));
temp->element=a;
temp->next=s->next;
s->next=temp;
int is_empty(stack s)
return(s->next==NULL);
void pop(stack s)
temp=s->next;
s->next=temp->next;
free(temp);
int top(stack s)
return(s->next->element);
void main()
char exp[100];
int i;
s=create();
clrscr();
printf("Enter an expression\n");
scanf("%s",exp);
for(i=0;exp[i];i++)
if(exp[i]=='('||exp[i]=='['||exp[i]=='{')
push(s,exp[i]);
else
