C++ :: Write Program That Uses Boost Library To Input String Date?
Apr 23, 2014I'm trying to write a program that uses the Boost library to input a string date in the format mm/dd/year and outputs to the string its corresponding day of the week. I wrote the program that I thought would accomplish this, but it doesn't seem to work. Below is the code I wrote:
#include <string>
#include <iostream>
#include "boost/date_time/gregorian/gregorian.hpp"
[Code]....
When I compile this using codeblocks it gives me the error "In function `ZN5boost9date_time19month_str_to_ushortINS_9gregorian10greg_monthEEEtRKSs':|
C:Users
osaDesktop est3........Liboost_1_55_0oostdate_timedate_parsing.hpp|67|undefined reference to `boost::gregorian::greg_month::get_month_map_ptr()'". And it takes me to the file date_parsing.hpp and highlights line 67. I don't understand why this isn't working.
C++ :: How To Write A Function That Takes Two Linked List As Input Arguments
Dec 7, 2012How do I Write a function that takes two linked list as input arguments these linked list contain numbers like this:
num1->3->5->2->NULL (assuming that number 1 is 352)
num2->4->3->9->1->NULL (assuming that number 2 is 4391)
The function should return 1 if num1 points to a linked list which represents a smaller number than the number pointed to by num2 linked list. Otherwise, it returns -1. If both linked list point to exactly the same number, returns a 0.

Visual C++ :: How To Modify System Menu To Execute A Function
Feb 11, 2013I wish to add the item 'Website' to an MFC Dialog app System Menu so that it can activate the following method:
Code:
void CMyDlg::OnWebpage()
{
ShellExecute( NULL, NULL, _T("[URL]..."), NULL, NULL, 0 );
}// OnWebpage()
I have tried this:
Code:
#define IDM_WEBSITE (WM_USER + 101)
//..
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
pSysMenu->AppendMenuW(MF_STRING, IDM_WEBSITE, _T("Website"));
}
[Code]...
The code compiles without error but and the 'website' item appears on the System Menu but it doesnt do anything.
I've inspected the following but don't really understand how it works and it seems to me there should be a simpler way to accomplish my end.

C++ :: Enforcing That A Function Does Not Modify Dynamic Array Pointed To By Pointer

I'm curious to know whether there is a way that ensures a function does not modify the memory pointed to by a pointer.
C++ :: Dynamic Function Execution Based On String Input
Jun 27, 2013I've got some functions and macros that I want to execute based on a string input that matches the function's name. I came across as this being a possible solution that I'd like to pursue IF it is possible to do. To clarify, I want to be able to look at a string and if the string matches the name of a defined function or macro then it will execute. Is there an effective way to do this (or is it even possible)?
It has to be pretty robust and dynamic given the project's purpose. Basically there's an input file that is being parsed and functions should execute if called upon in the file. I can't simply match strings to their corresponding functions in decision statements, as this isn't robust and isn't scalable.

C :: How To Write A Program To Make The User Input With Text
Sep 22, 2013I need to write a program to make the user input some text, and the first letter of each word has to be uppercase. (have to use while loops)
So for example lets say the user inputs:
i lOvE pRoGrAmMiNg
The output needs to be:
I Love Programming
Code: int main()
{
char c, lower_c;
printf("Enter Text");
while (c != '' && c >= 0)
{
if (c >= 'A' && c <= 'Z')
lower_c = c + 32;
else
lower_c = c;
[Code]...
I have started this code by making the letters lowercase (I don't know if this was the right way to approach this, ). I am not sure how proceed after this step, the step of making the first letter uppercase. (PS for the program, loops should be while loops)
C++ :: Write A Program That Will Read Names From Input File
Apr 24, 2014I have a lab with the following instructions:
Manually create an input text file called Lab22BInput.txt with the following data:
Dove
Doe
Alston
Zebra
Egg
Write a program that will read the names from the input file. Print out each of the names read to the screen. The program should go through the list of names and determine which comes 1st in the alphabet. The program should determine how many letters are in this name. Print out the name that comes first in the alphabet and the length of the name.
I have created the input file, and the data correctly outputs to the screen when I run the program. However, I do not know what kind of logic to use to sort them alphabetically and determine the amounts of characters.
So far I have the following:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
string str1, str2, str3, str4, str5;

C++ :: Write A Program That Opens Two Text Files For Input?
Nov 23, 2013I am trying to make a simple program, I would like it to be able to do the following, Write a program that opens two text files (input1.txt and input2.txt) for input .The program should write the followings in the two files. input1.txt:
This is the first line in input1.txt.

C/C++ :: Application Which Reads Input From Server And Write To A File
May 6, 2014Currently I'm working on a application which reads the input from the server and write to a file. Message stored in server : idle_message="维杰PC时钟" key_prompt="在按键"
Server will send a xml reply with encode type as "UTF-8". In my code I'm store in a char array. [ char * ch = "idle_message="缁存澃PC鏃堕挓" key_prompt="鍦ㄦ寜閿" msg came from server and copied from vs2005 watch point] After this I'm writing the same to a file in my desk using the API WriteFile. When i open the file in Editplus below is the content.
idle_message="维杰PC时钟" key_prompt="在按键" Again I'm trying to read the file and storing into the char array. Below is the content viewed by the watchpoint in VS2005.
idle_message="缁存澃PC鏃堕挓" key_prompt="鍦ㄦ寜閿? I'm trying to find the starting and ending chinese char and I'm converting that char to wchar_t using the API mcstowcs() for display, its coming as completely junk chars.
I can able to every place the chinese char are different. how to overcome this problem.

Visual C++ :: Write A Program Where The User Will Input Integer Numbers?
Oct 21, 2014I have to write a program where the user will input integer numbers. How many numbers they enter is unknown, therefor you should use a repetition structure for the input. When the user is done, they will enter -1 to exit.
Create a dynamic array if the size=2( the initial size must be 2) Repeat until user enters -1.
I have to do this without using vectors.
This is what i have, I cannot figure out what to put in main. I was thinking of a do-while?

Dec 20, 2014I'm new in programming, and trying to write a code in C. The requirement is following - to write a text, and to find frequency of 1 chosen character in it. The main thing is that program should check user input (for example, I want to check if user entered "char" --> then correct, or if entered "int" --> not correct). But the program still doesn't check. So I have:

C/C++ :: Comparing Input String To Type String Vector
May 29, 2014I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.
vector <string> currentSet; //read a list in from a file and has 9 items in it
cin.ignore();
string line;
getline(cin, line);
if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT
cout<<"match"<<endl;
}
C/C++ :: Input Lowercase String / Output Uppercase String

This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?

C++ :: Write Struct With String In Binary File
Jan 11, 2015I have a structure :
struct Entrainement{
string muscleCible, nom, unitesObjectif;
double objectifActuel, dernierObjectif, objectifInitial, capaciteInitiale, progression[10];
};
and I want to write in a binary file the structure. The following works perfectly....
(*pointeurFichierEntrainementBin).write((char*)&exercice, sizeof(Entrainement));
except when the string exceed 11 characters. I guess it's because it has to pick a fixed sized for the string? but what if I want to always be able to have string up to 200 character? because now I can't exceed 11..I know writing a string with c_str() works, but I would like to write/read the structure in one shot.
C++ :: Read String Of Characters And Write With Punctuation Removed
Oct 13, 2014Write a program that reads a string of characters including punctuation and writes what was read but with the punctuation removed.
This is how i did it:
string x("#punctuation!?=");

for(unsigned i = 0; i < x.size(); ++i) {
if(ispunct(x[i]))
x[i] = ' ';
cout << x << endl;
I am just not sure if thats how they want you to do it because it doesn't remove the punctuations it just replaces them with a space.
