I'm making a very first program. It's very little more then a simplistic calculator, but i'm having a problem with the cout function. It won't display any text what could the reasons be?
#include <iostream>
#include <string>
#include <sstream>
using namespacestd;
int main () {
do {
int(a);
[Code]...
Oh and i'm aware it's still riddled with numerous problems, I just have been working on the cout thing first.
I have been given an assignment to make a code to read some text nd display all the words nd the number of times they appear in another file or as output without displaying the repeating words. I made the code but its not giving any output.
#include<iostream>
#include<conio.h>
#include<fstream>
#include<string>
using namespace std;
void read(string);
string x,z,w;

I am asp.net C# developer. I decided to tackle C++, so I started today. This is probably something simple I am sure.
Code:
srand(static_cast<unsigned int>(time(0)));
int choice = rand() % NUM_WORDS;
string theWord = WORDS[choice][WORD];
string theHint = WORDS[choice][HINT];

The error is happening on the last output operator, just before the jumble variable on the last line.The error is:
Code:
Intellisense: no operator"<<" matches these operands
operand types are: std::basic_ostream<char, std::char_traits<char> <<std::string
I understand what its saying, but jumble is a std::string
Here are my preprocessor directives and using statements
Code:
#include "stdafx.h"
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
So I'm really stuck trying to figured this bug on the program that is preventing me from displaying the text of my program..
#include <iostream>

#include <stdio.h>
using namespace std;
int main () {
ifstream infile;
ofstream offile;

I'm working on a program that can load all words from a dictionary "English2.txt" (it's attached to the post), then put every word into a 2-dimensional matrix (every line is reserved for one word) and display them. After loading every word into a matrix, when I try to display first 8 words with printf, I can't do it without '' at the end of a line. Otherwise only the 8th word is displayed... What's more, when I try to read the length of the first word with strlen, it says, that it has 4 characters (in fact there are only 3 and it's the word "AAA"). What could be the reason for that?
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdint.h>
int main()
{
FILE *fp;
char buffer[32];

How to get a txt Outfile to display a Checksum.
Code:
ChecksumFileDisplay = fopen(ChecksumFileDisplayPath, "r");
fprintf(ChecksumFileDisplay, BigEndianChecksum);
That's what I have but it doesn't like the fprintf function because BigEndianChecksum is an unsigned int and it wants a pointer to a const char. Is there a function similar to this that will display an 8 digit integer in a txt outfile?
i have turbo c++ 3.0 installed . my program is compiled without error and is running. but when i choose option to display scores in the consol , it hangs . check my code. i have to run this on same compiler. i just want to display all the contenets of text file .

Is it possible to display data from a textfile and also save data in to a textfile, reason being is for me to create back-ups of data into a textfile hidden somewhere in a safe location in the local disk or server in case of database error and failure.

My requirement is,
Read *.bmp image and displaying bitmap image with scrollbar in a MFC dialog application.
I was done using this
I was read the *.bmp image as a pixel data and stored by 2D Array,
Now i want to Display this 2D array as bitmap image with scrollbar separately in the same dialog. How can i display bitmap with scrollbar using 2D array?
I made a dialog to have a customizable msgbox. (custom icon, custom caption on buttons). This is how I try to display an icon on the dialog but it is not working.
HICON hIcon = LoadIcon(NULL, IDI_QUESTION);
HWND hImageCtl = GetDlgItem(hDlg, IDC_STATIC);
::SendMessage(hImageCtl, STM_SETIMAGE, IMAGE_ICON, (LPARAM)hIcon);
//SendDlgItemMessage(hDlg, IDC_STATIC, STM_SETICON, (WPARAM) hIcon, 0);
I have written a MFC dll to interact with an API and it is run by the target program. the first 100 bars are drawn properly but then the program ceases to operate. I am guessing I have a memory leak but I probably just dont understand what I am doing as I am quite new to programming MFC GDI. Here is my code that causes the trouble...
The variables coming in are commented out to facilitate testing and so it would be displaying the same bars over and over because of this. it worrks for 100 bars, then crashes.
void MainDlg::SS_UpdateChart() {
// the chart plot is completely recalculated each time a new bar is shown
// 300 is plottable height
// 400 is plottable width, 39 bars
int displayChartHeight = 300;

I am having one issue with my project. We are making a game of Nim code.I'm 99% done with it, i worked hard on it and i feel like i did a good job, however my project is not displaying the matches i want. For example, it display's the inital number of them 23. But once the first player subtracts a number, it doesn't display matches for player 2, just the number of matches remaining. Then as i keep running the program the same thing happens. This is what it's supposed to
output:
"Input/Output sample
WELCOME TO NIM
------- -- ---
Enter the starting player's name (no spaces)-->John
Enter the second player's name (no spaces)-->Mary
There are 23 matches.
ooooooooooooooooooooooo
|||||||||||||||||||||||
Player John please enter the number of matches to remove-->2
There are 21 matches.
ooooooooooooooooooooo
|||||||||||||||||||||
Player Mary please enter the number of matches to remove-->3
There are 18 matches.
oooooooooooooooooo
||||||||||||||||||
Player John please enter the number of matches to remove-->1 "

I have a text file that is divided into blocks:
#1
1:animal
2:food
3:moves
4:oxygen
#2
1:eats:2
2:breaths:2
3:can:1
4:is a:1
#3
1:1:2
1:3:3
1:2:4
And the following program that displays block by block:
StreamReader streamReader = new StreamReader("G:LAB123LABWORK2.txt");
int block = 0;
while (!streamReader.EndOfStream) {
string line = streamReader.ReadLine().Trim();
if (line.CompareTo("") == 0)

My problem is am supposed to add a verification code so that if i put a string e.g 1:?:? it returns the block where the string is found and gives of all possible answers.

I am wanting to be able to add as many different instances of data, while the user has not stated 'n', but then it only ever writes back to the screen the input for the last set of data. Where as I want to display back to the screen all the data that has been entered.

This is what my code looks like
class Transaction{
private:
char type;
double amount;
double balance;
string description;
[Code] .....
This part is what I am having trouble with as this section is not printing anything.
for (int i = 0; i < transactions.size(); i++){
cout << transactions[i].gettype() << " ";
cout << transactions[i].getamount() << " ";
cout << transactions[i].getbalance() << " ";
cout << transactions[i].getdescription() << " ";
}
}
Other than the theoretical difference between cout and cerr where the former puts values to the monitor and the latter puts values related to errors to the monitor, is there any real difference here? Why not use cout when you want to send anything to monitor? Why use cerr at all?

Iam working with arrays and i cant get to the write solution to cout the characters.
the Question is : Write a program that inputs a character string from the user as an input (using cin.get())and store it in myStr[ ] array.Assume that the length of the input string is less than 100 characters and the string may contain lower case, upper case, and/or symbols.The program should then print the number of lower case, upper case, digits, and symbols along with the characters themselves.
my code :
#include <iostream>
#include <string>
#include<iomanip>
using namespace std;
int main() {
int ctr1=0, ctr2=0, i=0, ctr3=0;
[Code] ...
What i have now, how can i cout the uppercase characters and the lower case characters and the symbol characters !
Finally got to functions. Made a simple one that adds two numbers:
Code: int add(int a, int b){
cout<<"a+b=";
return a+b;
}
It refuses to give an output unless I use cout.
If I just call the function like so: "add(12, 24);", shouldn't it print out a+b=36? It only prints out "a+b=", unless I use "cout<<" ahead of the call.
My simple question is why does it need cout ahead of the call? Shouldn't "return" do its job and print out the number?
i ran the following code in the latest version of code::blocks and it tells me that the objects cout and cin are not declared in this scope. what is the problem?
I used to use Turbo C++ 3.0 and i had no problem whatsoever with that compiler. But now i am trying to move to code::blocks but it is proving very very hard as all the standards have been changed.
I am a school student and thus, we had been told to practice on Turbo C++ 3.0 and now i am unable to unlearn it. Also, if i use printf in place of cout there is no error but i want to use cout as it is what i am comfortable working with.
#include<fstream>
#include<conio.h>
int main() {
using namespace std;
char name[20];

Is there some document to which i can refer so as to get the latest C++ standards which is C++0x i believe?
I m working calculating stuff in files, input and output data, etc..., the question is the following: I output double numbers with:
myFIle << fixed << setprecision(10) << double;
The problem i got is that when a numer is like 193123.2 it prints like 193123.200000..., so finally, ¿how can i print it with any additional 0 that i need?.
I'm trying to build a new project and i installed some new libraries in it but when i try to compile any code it doesn't give me any value just press any key to continue, i didn't make any files but one and even if i tried to do this simple task it doesn't cout any result:
#include<iostream>
using namespace std;
int main() {
cout <<("ha");
system("pause");
return 0;
}
