C++ :: Copy Elements Of One Stack To Another - Push Method Not Working
Oct 27, 2014
I am trying to write a method (copyStack())that copies the elements of one stack to another. So I am using a Type variable and a while loop, assigning the top of the first stack to the variable, and then using the push method to push the Type variable into my second stack (then poping the first stack). However, whenever it comes time to print the second stack (the one I am trying to copy into), nothing shows up. I know that the program is reaching the copyStack function, and I know that when I put a regular string in for the Type variable, it passes that string along. But for some reason, when I use the variable, nothing happens! Here's what I've got...
I am incredibly new to c# and am just learning to work with queues and stacks. I have created a simple queue of nintendo games and used the Enqueue and Dequeue for practice. How can I copy this queue into a stack?
So I was wondering if I were to empty the elements of a stack into a queue, but i only wanted to empty the even numbers or the odd ones. What would the if statement be to accomplish this. Im guessing for even it would be something like if(number % 2!=0)? What about for odd?
I have a program that consist of a postfix calculator for a class assigment, my program is basically done, however I am missing how to loop through the stack and print each element of it. My output is suppose to look something like this:
Token: 4+5 (my token would be the infix expression that the user inputs)
output:45+ (my output would be the postfix expression)
Stack(bottom to top) :empty + + empty (This is suppose to be the process of the stack, but I do not know how to get this values to print out)
and I already have the token and output part, however I do not know how could I get the stack values, in order to print them out.
My goal is to copy only the elements of string 2 that are equal to string 1 into a new string. I tested this idea with an array of integers and it worked, but didn't work for the strings.
Code:
#include<stdio.h> main() { int scan1; char arr1[40] ; char arr2[40] ; char arr3[40] = {'_',.....,'_'}; /*for sake of brevity with post*/ }
I am trying to retrieve the elements in an array to print them. I am pretty sure I have everything right, but it is not working. There are 5 values in the array {3, 4, 10, 5, 6}, but the first two elements (supposed to be 3,4) are coming out a 0,-2654238590. The last three elements are coming out correct.
void addDynArr(DynArr *v, TYPE val) { /* FIXME: You will write this function */ assert(v != 0); //resize if necessary if(v->size >= v->capacity)
I've been trying for more than one month to access a method found in a library called libcocosnas_static.a. I'm using Cocos2d-X version 2.0.4. The library has been used many times by my company to make games using cocos2d-1.0.1-x-0.12.0 without any problem.
This is what I've done: 1- I added the include paths of the library to both eclipse and Android.mk 2- Included the .h file using #include "NASPlatformUtil.h" 3- Added the libcocosnas_static.a file to the proj.androidobjlocalarmeabi folder 4- Added "LOCAL_WHOLE_STATIC_LIBRARIES += cocosnas_static" to the Android.mk file 5- Called the function using: NASPlatformUtil:: openUrl("http://xxx.xxx.com/");
I can right click on the function, click Open Declaration and get it without any problem, but the compiler keeps on giving me that dreaded error...
I was wondering if it's possible to push a button on a website programatically. Unfortunately the button link is invisible, otherwise I could simply use the URL it links to. So is there a way to do it in c++ and if so, how?
I am trying to use push back in a 2D vector but I don't know how to. This is what I have:
vector <vector <BigInt> > matr;
for (BigInt i=0;i<rij;i++) { for (BigInt j=0;j<kolom-1;j++) { matr.push_back().push_back((i+1)^(pow-j)); } }
I quickly invented something but that doesn't work obviously. it should be equivalent to this: (the only problem in the code below is that those indexes don't exist yet that's why I need push_back())
for (BigInt i=0;i<rij;i++) { for (BigInt j=0;j<kolom-1;j++) { matr[int(i)][int(j)]=(i+1)^(pow-j); } }
I have a question similar to the one here: [URL] .....
The main difference is I would like to pass a method of derived class as a parameter to some other method in its template base class.
template <typename BaseType> class Base { public: typedef void (Base::*Callback)(int A);
[Code] .....
The above is an example which does not compile. My compiler complains that the two BaseMethod() calls in DerivedMethod() are invalid uses of non-static member function.
Is this not possible to do, or is my syntax simply wrong? All I want is to be able to pass as an an argument to a method in the base class from the derived class some callback as a variable for the base class to invoke later.
Code: class moClassValueContainer { public: moClassValueContainer(); moClassValueContainer(string,int); [Code] ....
In my main.cpp, I have blow loop
Code: for (xml_node tnode = it->first_child(); tnode ; tnode = tnode.next_sibling()) { Container tmpContainer(tnode); if (tmpContainer.getType() == SINGLE) { string t = tmpContainer.getName();
[Code] ....
I cannot push_back(t). I examined the code with debugger, t has correct string value assigned, but even after 20-30 iterations, there is no element for headerFields vector.
I've been playing around with making a linked list in C and am having trouble adding to the beginning of the list. For the add_beg() function: the statement "head = newNode" only works locally. This leads me to believe this is a pointer problem. However, the add_end() function works correctly. Ideally, I would like to print "0 1 2 3 4" after using the add_end(root, 0). Currently, print only gives me "1 2 3 4".
#include <stdio.h> #include <stdlib.h> //Create a node struct typedef struct node { //data int val;
How to avoid using Backspace character with push_back? I'm making a software as an ATM, so when the user try to enter the password the user only sees *******, but when trying to delete it doesn't delete a character. It just adds a new one. Here's my code:
#include <string> #include <vector> using namespace std; class Question { string title; vector<Thing*> posAns; vector<Thing*> negAns;
[Code] ....
error: no instance of overloaded function 'std::vector::push_back()' matches the arguments list argument types are (const Thing *) object type is: std:: vector<Thing *, std::allocator<Thing *>>
So it cannot be constant, what if I just leave it non-constant? Will it be safe?
I have a thread with a while(1) loop in it. When the user push the stop button I would like that thread to end.
I thought about creating a bool and checking its value periodically in the thread and when I push the stop button I change the value of the bool for that the thread breaks out of the loop and finishes.
How to output vector contents using the push_back function. My program reads in values just fine, but it does not output anything and I've been stuck on why.
here is my code:
#include <iostream> #include <array> #include <vector> using namespace std; int duplicate( vector < int > &vector1, const int value, const int counter)
