C/C++ :: Recursion In Stack To Get Maximum Element And Copying Stacks
Nov 22, 2012
I am still new to stacks and recursion and am trying to implement two functions using recursion to get the maximum element in a stack and copying one stack into the other but it keeps repeating some elements and i dont understand why!!
Any example of a graph search algorithm that uses a recursion and linked list based stacks to determine a route from a single point on a graph to another single point on a graph?
I designed one mfc vc++application in which data received from udp is stored in file as well as in stack.I used stl for stack; it stored elements as per receiving order,but i want to return repetitive number from stack,how to use stack as function parameter & retrieve elements of stack as an array? I write code for push elements in stack given below.
<template< typename T > void pushElements( T &stackRef,int value) { stackRef.push( value); }/>
So I have linked list and function which deletes element if next element is bigger, so my code is working but its not working with first element, in the comment I have wrote code which I would code for checking that first element, but when ever I check it is blowing up all program.
#include <iostream> using namespace std; struct llist { int x; llist *next;
I just started by defining a stack class (stackDouble). I need to write a program that accepts an infix calculator expression, with the following operators (**, exponentiation, /, division, and, -, subtraction. The operator precedence is exponent, division, and subtraction.I need to use a stack of doubles and a stack of strings, of which I can write two classes, or write a single stack template. The user will input the expression just via cin, and there will be a # before every number, a ! before each operator, and a . at the end of the expression. '#', '!', or '.' can be input into a char variable, numbers into a double variable and operators into a string variable.
For example, the following would output 6:
# 3 ! / # 2 ! / # .5 ! ** # 2 .
As stated above, I already made up a stackDouble class. What would I need to do to create the other class (I don't think I want to do it with a template)?
Code: #include <iostream> #include <string> using namespace std; class stackDouble{
Given a set of different types of paired symbols; determine whether it is balanced or not (the opening and closing version of each type are paired correctly). Any other type of characters may appear in the input will be neglected.
For example: (**(*[*])****) is balanced, also [{}**[]**()]** is balanced. But ((*{*)*}) is unbalanced as well as [()***[]***{*(*)}.
Write a C++ program that requires a string containing and expression as an input from the user and check for balanced bracket pairs using stack data structure.
Here is my code which give me nothing when I run it.
#include <iostream> #include <string> using namespace std; class CustomStack {
i feel like im really close to completing this but i cant seem to get the result printed out i dont think im calling my evaluate function correctly and its not performing the operations..
#include <iostream> #include <stack> //stack header file using namespace std;
I have a global list that contains smaller lists of char arrays. I have an issue where when I'm reading back the inner lists the last element of one list seems to point to first element of the next.
So my data looks like the below (values separated by commas with the pairs separated by tabs. The last pair in a line is the same as the first). When I read the first list back instead of seeing "456.678,678.98" as the last element in the list. I see "435.67,234.98" twice: at the end of the first list and start of the other. I have debugged when the list is populated and can see the correct values going in so I can't figure what's happening.
obstacle_list = op_prg_list_create(); while (fgets(line, sizeof(line), obstaclePositions_traj_file) ) { token = strtok(line, " "); //Pull the string apart into tokens using the
I have an std list of type double.. and the list is always guaranteed to have just 2 elements. I need to get the value of element 2 minus element 1. What is the least amount of code to accomplish that?
I tried this:
Code: list<double> dList; dList.push_back(1.0); dList.push_back(2.0); list<double>::iterator iter = dList.begin(); list<double>::iterator iter2 = dList.end(); double result = *iter2 - *iter;
How to implement the main queue functions Enque() and Deque() using two stacks S1 & S2. You allowed only to call push () and pop() functions of the two stacks to implement Enque()and Deque() functions.
#include<iostream> using namespace std; const int size=5; int arr[size]; int front=-1,rear=-1; bool isfull() { if(rear==size-1)
I was given a task to convert infix to post fix using both linked lists and stacks in the code so this is what i have written but the problem is it is giving me same error at three different places "missing function header(old style format?)
#include <iostream> #include <string> using namespace std; const int size = 100; class stack{ private: // Declare a structure for the list
How to make a C function, that will be copying string to the clipboard?(so during execution it copies to cliboard, and after the program ends its execution I will be able to do "Ctrl-V" and paste the things copied)?.
I assume that linux have some sort of in-kernel clipboard which can be filled with some systemcall?
how I would copy a file's contents into a char buffer and copy it over to another file for files that can't be opened/read in notepad? (Example: a rar file or a .exe ) Not sure if that makes
I'm having some trouble with copying one I/O stream into another. I've put the first one into an array but I cannot get my second prompt to copy the .txt file the first prompt sees and outputs to the console. When I try and grab the info from the .txt file my first prompt sees I only see blank space in my .txt file.
#include <iostream> using std::cout; using std::cin; using std::endl; #include <fstream> using std::ifstream; using std::ofstream;
So I'm writing a function isPalindrome() that can accept a string as an argument, and copy from it only the alphabetic characters in the argument (original) string to another string named alpha_array which contains only the alphabetic characters. Then the function should be able to call the isPurePalindrome function to determine if alpha_array is an ordinary palindrome.
The problem is that when I call isPalindrome in main, the program crashes.
Here's the code I have for isPurePalindrome and isPalindrome:
Code:
/* 1 */ int isPurePalindrome( const char * sentence ) // Can accept strings, array and pointer arguments { // Declarations
