As part of my hw assignment i need to reverse a string using stacks. This is my attempt and so far its not working.

I made a simple little program that takes text from the clipboard, and spits out all the lines I've copied one at a time (so my program can analyze it).
everything works perfectly, except, it spits it own in the wrong order, I want it to spit out from bottom to top. but currently it spits out the data from top to bottom. here is my code :
Code:
#include <iostream>
#include <Windows.h>
#include <string>
#include <sstream>
using namespace std;
int main() {
HANDLE clip; // assigns the var. clip to hold a handle ID.

I want this loop to run backwards! Like it say's what I want to work backwards. Where as I know how to flip a while loop like this: while(x < 5), how to flip a loop like the one I'm using. how I can do this?
If I am executing following code after reversing it is giving "1" but I need "0001".
#include <stdio.h>
int main() {
int n=1000, reverse = 0;
while (n != 0) {
reverse = reverse * 10;

I was browsing the web looking for simple yet fun programming challenges and crossed this one. I figured out how to reverse the string in place but I want it to read "blue is house the". I approached it in two ways for the heck of it. My idea was the second one, the first one I googled. I didn't know a simple rbegin() could do that, pretty neat.
I found the question here.[URL] ....

#include <iostream>

Here's what I have to do: Using strcpy() pass it two strings of characters (such as a name like John Johnson) and copy the second string into the first, in reverse order, and print both. Write a main to exercise your function and to illustrate that the function is working properly.

I'm trying to reverse every even word in a string (not all of it). But I keep getting an empty output.

How do reverse every alternate words in a string that I read into my program:
e.g. The mouse was caught in a clothes peg.
reversed (including the full stop)
The esoum was thguac in a clothes gep.
I could program it to reverse the whole sentence. But no clue how to reverse certain words such as every even word. Do I need a function and/or loop to solve this?
#include<iostream> // allow input and output
#include<string> // allow for larger entries of characters
using namespace std;

I am supposed to take the three string lines from a text file and then individually reverse them and state whether or not they are a palindrome. I have the three lines from the text file into string variables already but I am not sure on how to reverse them and then see if they are the same reversed(palindrome)

EDIT: Ignore line 123 and down in the code. That was merely test code and will not be used.

Do not assume i know about getchar and putchar.
Here's my program: - Program which inputs a string from user, reverses it and displays it.
#include <iostream>
using namespace std;
void string_reverse (char [], const int);
int main() {
const int arraysize = 10;
char string[arraysize];
[Code] ....
In the string_reverse function, I have declared temp character type array but on line 38, the
compiler is throwing 3 errors: -
error C2057: expected constant expression
error C2466: cannot allocate an array of constant size 0
error C2133: 'temp' : unknown size
I have declared a constant integer arraysize in line 35. Now I have no clue why is this happening because I think as I have declared it as a constant integer variable, this should not happen.
I understand that the strrchr function is supposed to search for a string from the reverse. Unfortunately, mine isn't doing that.
#include <stdio.h>
#include <conio.h>
int main() {
char userinput[100] = "null";
char searchchar;
char *s;
char try_Again;

How to make it so an output for a program would print out the string in reverse/backwards? I was just curious on how to do this.

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{

How do I make a Template that has 2 stacks ?
Code:
template <class T>
class A {

template <class T>
class B {

I am trying to create a deque using these stacks but I failes again and again.

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;

this is the code for the functions:

string x=firstStack.top();
firstStack.pop();
//secondStack.push(x);
