I thought that an operator performs a permanent change in a local variable. For example, if x is 00000000 00000000 00000000 00000011 (a 32 bit unsigned integer that resolves to value of 3) and p is 2, in the expression "return (x >> p) | (x << (s - p))", the right shift would permanently change x to 0 and the time we evaluate x again in "(x << (s - p))", x will already be 0. If that's the case, then this function doesn't make sense. This function makes it seem like that the >> and << operators do not change the value of x. It makes it seem like first we right shift x to 0 and then left shift by 20 bits to make x 11000000 00000000 00000000 00000000. If that's the case, then the function does exactly what it is supposed to do (rotate the bits). So which is it?
unsigned int rightrot(unsigned int x, unsigned int n) {
size_t s = sizeof(x) * CHAR_BIT;
size_t p;
if(n < s)
p = n;
The purpose of the code is to read in state names, say california and print CA. However, if it was a state with two words, it would read in only the first letter of each. I.E New Hampshire would be NH.
here's my code: #include <iostream> #include <iomanip> #include <cctype>
[Code].....
I am able to get the one word states and tried getting the two word states but it doesnt work.
I am making a finite state machine for a lab. I have here a 2 files with the code for the FSM. I know it isn't finished yet, I know what needs to be put in. The only things I would need help on are the errors that I get.
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)
Question: State the values of each of these int variables after the calculation is performed. Assumed that, when each statement begins executing, all variables have the integer value 5.
When running my code in Visual Studio, there is a particular point in the code where my program is crashing. To debug this, I am adding a break point in Debug mode just before that point, and observing what happens as I step through the code. However, to get to this break point in the code takes about a minute of running the program. So I'm wondering if there is a tool in Visual Studio to reload the state of a program's memory from a previous run, so that I can immediately get to the break point without having to wait for a minute each time?
This code came from a example at the boost example list: URL.....I want the networking to start when the multiplayer state initializes. This is how my program basically looks like:
In the following code example of the State Design Pattern, in the main code at the bottom it defines an instance of class Machine, and then calls Machine::off;. Why doesn't it instead call fsm.off;?
Machine fsm;
Machine::off;
Then I tried imitating that by adding a class Abba, and then doing:
Abba a; Abba::DoStuff();
but that didn't work. Why?
Full code example:
// StatePattern.cpp : Defines the entry point for the console application. //
#include "stdafx.h" #include <iostream> using namespace std; class Machine { class State *current;
I'm supposed to create a circular buffer that reads an input file and outputs data after running though basically an integral equation. Everything my be referenced by pointers. When I build I am being told segmentation fault: 11. From what I have gathered that means there is a problem with my memory allocation correct? I'm including the custom header file and the main.c as well.
I am a beginner trying to write a program that would state a user's chinese zodiac and horoscope sign after inputing his or her birthday. I have been, however, having trouble getting the program to run correctly.
I've been trying to figure out how to implement a way to save this board state throughout a user's inputted path. At the end, I need the output to print out the board states (user's path) of how he or she got the puzzle solved. This puzzle is the 15 Puzzle; but we have it to change by the user's input on what size they want to play (3x3 to 5x5). How to save the board state of each user input, then print those out in order from beginning to solved puzzle state. Subsequently, I would also need transferring the board state to change with using a vector to store the size based on user input. How to proceed, using a first search to solve the puzzle from the current board's state.

I keep getting an error here and cant quite figure out why,
Code: else if (mainMenu == 3){ cout << "Please make a selection" << endl << " 1) Withdraw from account" << endl << " 3) Back to main menu" << endl; cin >> withdrawMenu;
I am making a program that allows you to add two big numbers that are larger then what int can handle together. I think I have done everything to accomplish this but when I try to instantiate the program I get a error Expression must have a class type.
Here is my main file that is supposed to instantiate the program.
I wrote a program, that generates 20 random integers, and stores them in an array. Then I decided, to build more functions to it, i.e why not have it to display the lowest integer of an array. I created my function,
Code: int minValue( int field[ ] )
and got my code in side, which (technically) works. In my main() function I'm calling
Code: printf( "The smallest value of an array is: %d ", minValue( field[] ) );
and I'm getting an error trying to compile it.
Code: randomArray.c:62:74: error: expected expression before ']' token printf( "The smallest value of an array is: %d ", minValue( field[] ) );
I am trying to create a NFA from a regular expression. I have a grasp on reading in the regular expression and being able to make a stack from it. The part I am struggling on is mapping the characters in the regular expression to an integer indicating the variables order in the expression. I am just not sure how to go about this.
My code so far... Code: #include<stdio.h> #include<stdlib.h> #include "stack.h" int main(void) { char expression[80];//array to store regular expression
So, I think that the above expression converts to 0x49 | 0x00 ... and the complete expression should be 0x49 for me.
But, the compiler gives me the result of 0x4949 as two bytes.How does the compiler calculate this expression as two bytes?show me the steps included in the calculation of this expression?
After compiling it is giving error as : foo.cpp: In function ‘int Foo_max(Foo*)’: foo.cpp:26:37: error: expected primary-expression before ‘int’ foo.cpp:26:46: error: expected primary-expression before ‘int’
I am a c++ leaner, I am trying to create a BST tree for this expression: 2346*+/8+, and do inorder and postorder to get the in-fix version, and postfix version of the expression. I am having difficulty to create the binary tree for the expression. Here is my peso code:
