Help with CharStack() pop() and push() 13 Years Ago by vishal1949 I just wanted to know what would happen if you abuse the CharStack class by pop()ing more characters than you push()? Would it be an error of out of exception or something else. Re: Help with CharStack() pop() and push() 13 Years Ago by JamesCherrill Which CharStack class would that be? Re: Help with CharStack() pop() and push() 13 Years Ago by hfx642 Agreed... I don't find any documentation about a class called CharStack. A stack (of any type) is a list construct the programmer must create via array. using charStack(); 13 Years Ago by vishal1949 … could enter are 20 or 25000 lbs. I wrote the charstack and the pop() and the push() but dont know how… Re: Help with CharStack() pop() and push() 13 Years Ago by Ezzaral Read the API docs for the class. Re: Help with CharStack() pop() and push() 13 Years Ago by hfx642 Besides... Your code should be checking not to pop() if there are 0 elements in your stack. Re: Help with CharStack() pop() and push() 13 Years Ago by JamesCherrill So this is a class that you have written / must write? In that case the answer to your original Q is "that's up to you". Throwing an Exception would be a reasonable thing to do, because it would be an error. Re: using charStack(); 13 Years Ago by nmaillet You need to go through a Java tutorial. Couple things from a glance: Each class/interface needs to defined in its own JAVA file, with the same name. For instance, SaturnSL1 must be in a file called SaturnSL1.java. You should be declaring the ParkingGarage class outside of the main method(). Re: using charStack(); 13 Years Ago by hfx642 You have to keep track of two things. a) The number of vehicles in the stack b) The total weight of the vehicles in the stack When you push()/pop(), add/subtract your count/weight. BEFORE you push()/pop(), check for your upper/lower limits. You can't pop() when you have 0 elements. You can't push() when you have 20 elements, or if the added … Re: using charStack(); 13 Years Ago by raymagosi first of all i think you need to understand the concept of overflow and underflow. These two will help you understand your problem, before you push() or pop() you have to use a condition to check the number of vehicles in a stack as well as the the total wight.For more information on this problem get any book of [B]DATA STRUCTURE AND ALGORITHMS[/B… Expert advice on DIY stacks please... 13 Years Ago by garu525 …bool full ( const charStack& ); bool empty ( const charStack& ); void push ( charStack&, char ); char pop ( charStack& ); char top ( charStack& ); bool …msg << endl; cin.get(); exit ( EXIT_FAILURE ); } void initialize ( charStack & stack ) { char *newParens; newParens = (char *) malloc(sizeof(char)… C++ stack 10 Years Ago by TObannion …top; int count; public: //constructor CharStack(char); //not written inline ~CharStack() //written inline { delete[]stackArray;…(); bool isEmpty(); char getCount(); }; //function definitions //constructor CharStack::CharStack(char size) { count = 0; stackArray = new char… custom made queue/stack - having problems 16 Years Ago by JAGgededgeOB172 …s); void pop(); bool empty(); char top(); }; charstack::charstack() { stack_top = 0; for(int count_1 = 0;…lt; endl; return; } stack_top--; return; } bool charstack::empty() { if(stack_top == 0) return true; else… Re: custom made queue/stack - having problems 16 Years Ago by JAGgededgeOB172 …bool empty(); char top(); }; charstack::charstack() { head_chrstck = NULL; } void charstack::push(char &s) {… temp1_chrstck->next = temp_chrstck; } return; } void charstack::pop() { if(head_chrstck == NULL) return; else { … Re: C++ stack 10 Years Ago by TObannion … to test the IntStack class. //Feb 17, 2015 #include "CharStack.h" #include<iostream> using namespace std; int… main() { //declare an instance of CharStack, size 5, called mystack1 CharStack mystack1(5); char a='1',b='2',c… Re: C++ stack 10 Years Ago by Nutster The problem is on line 14 of the CharStack driver program.
