Suppose I have a txt file that I want the contents printed to the console in such a way that every five words are colored blue and the following five are red. How do I accomplish such a task? I am currently only able to print the contents of the file in regular color using ifstream.

I have saved the file into a resource file within visual studio and I am trying to run the code to where the file will be shown when I run the program. I know that the program is running and the file is there because if i misspell the filename it will give me the error message. I don't know how to make the contents of the file display. Here is what I have so far.

I've created a text file with the numbers from 1-450. After writing code to retrieve and print out the contents in the text file, the compiler only printed out the numbers 124-450. Is there a reason why this is happening?

I have to write a c++ program to read html code and do bunch of stuff. One thing that i have to do is to count the no of attributes and sort them in descenting out and print out only first 10 frequently used attributes. I counted them using maps and sorted them using multimaps but now dnt knw how to print only 10 elements
for(std::map<string, int>::iterator it = Element.begin(); it != Element.end(); ++it)
Elements.insert(pair<int, string>(it->second, it->first));
for(std::multimap<int, string>::reverse_iterator it = Elements.rbegin(); it != Elements.rend(); ++it) {
cout << "Element: " << it->second << " : " << it->first << endl;
}
This is how i did it . How to display only 10 elements and not all the elements.
I have been trying to read a comma separated .txt file into an array and print it to console in C++. The txt file consists of two columns of double type data.

I'm new to programming and i'm trying to do a certain task. I want to use a for loop to read certain data from a txt file and print them to a console. I'm trying to read student names and their grades.
Something like
3 // 3 represents the number of students.

The data may vary but it's always in this format.
I am trying to print the content of the CRichEditCtrl v 2.0. The problem is that when I want to use pagination (with A4 pages), the printed text (which is just 4 sample line with 40 chars at most) at the code lTextPrinted =FormatRange(&fr,TRUE); is always lesser than the actual text pointed by the lTextLength variable making the loop run for ever. notice that using the RichEditControl Version 1 it works fine.
Check the code. I am attaching also the full source code at [URL]
Code:
CPrintDialog printDialog(false);
if (bShowPrintDialog) {
int r = printDialog.DoModal();
if (r == IDCANCEL)
return; // User pressed cancel, don't print.

I need to create an overloaded cout that will print the contents of an array. So I can say output << a << endl;
And it will print the contents of the object a... which happens to be an array.
class info:
class List {
public:
List();
bool empty(); //returns true of false if empty
void front(); //makes current position at beginning of list
void end(); //makes current position at the end of list

I understand this code, I am simply calling the size method from the program, but i don't know how to pass in the array so that i can print it line by line... simple syntax i am sure... but the whole thing is baffling me... I need to be able to call this on any variation of the class, so it cannot be specific to any one array.
I am having some trouble tokenizing some strings in C. I am trying to take in a string dynamically and spit print it to the console tokenized using the spaces as delimiters. I have tried using frets() and scant() as well as playing around with pointer values to no avail.

We have a C++ 5.0 app that does something like this:
Creates the excel dispatch, exports the data, etc...
...
then calls these functions:
xlsApp.SetDisplayAlerts(TRUE);
xlsApp.SetVisible(TRUE);
xlsApp.SetUserControl(TRUE);
This has always worked to display the excel spreadsheet in the foreground, most recently on Windows Server 2003.
Now, testing on Windows Server 2008, the excel spreadsheet is created, but in the background. How to force it to the foreground?
I'm writing a program that stores records into a file and then these records can be printed out. A last name, first name, and score is stored to be exactly 36 characters long (using leading spaces to pad) making it easier to retrieve specific records. For example, three records stored in the file would like like this: (the underscores are simply to illustrate the distance, they are not in the file itself)
_______lastname_______firstname__90__________lname __________fname_100___________last___________first __60
When printed out, the names are formatted as follows:
lastname, firstname: 90
lname, fname: 100
last, first: 60
However, when I print them out this is what I get:
lastname, firstname: 90
lname, fname: 100$
last, first: 60H
For some reason, for any record after the first, an extra character is added to the end. These characters are not in the file, so I was thinking that the array for some reason wasn't being filled completely, (the array is initialized to size 36 and 36 characters are read from the file using fread) so it was printing out a random character assigned to the 36th array position. Except the character never changes, (always a $ for record 2, H for record 3, l for record 4 if i remember) and I've tried reducing the array size or the number of character read and it's the string that gets altered, the random character always remains. I figure the problem must be in the print_records function (appending seems to work no problem). Anyway here is my print records and appending records code.
Code: /*
- Prints a single record stored in the file pointed to by ifp.
*/
void print_record(FILE *ifp, int record) {

Right now I'm working on an assignment where I need to take the data from on file encrypt it by adding 5 to each byte and then save it to a user specified location. I think I'm close to having it done but I've run into a hick up. After I get the user input for where the encrypted data should be saved the program seems to never end. This is the code I have so far

So I insert values from a vector into a list and into a multiset, and I noticed zero is added to their contents! I had to do a whole lot of debugging to find out where the error was, how can i stop this thing? Code which generates such error...
infact i checked the content of vector ups to be sure that there was no zero in it, but after loading into list combi_t * head, it seems like there was a zero added and this is giving me errors when i call function master_roller...
Code:
void ins(combi_t * &testa, int &numero, int &num, int &no)
{ // if (ricerca(testa, numero) == 0)
//{
combi_t *temp = new combi_t;
temp->val0 = numero;

I have a character pointer that points to 4000 bytes of valid data. I need to write these valid contents pointed to by this pointer into the file. I am looking for the most optimized way of doing this. I am using the below logic which seems trivial. Any better approach to accomplish the same?
/* length is the number of valid bytes of data */
void parse_contents(const char *data, int length) {
int j = 0;

I have a program that's not doing what I want it to do. This is the assignment:
The nth term of the sequence of triangle numbers is given by, tn = 1/2 n (n+1); so the first ten triangle numbers are:
1, 3, 6, 10, 15, 21, 28, 36, 45, 55,...
By converting each letter in a word to a number corresponding to its alphabetical position and adding these values we form a word value. For example, the word value for SKY is 19 + 11 + 25 = 55 = t10. If the word value is a triangle number then we shall call the word a triangle word.
the 'words.txt' has a bunch of words in this format:
"ABSTRACT"
"YOUTH"
there's about 1000 words in that format.
And for any triangle words I find, I put it into another text file which I called triangle.txt.
Now for my program, it pulls the 'words.txt' file just fine but it doesn't recognize any of the words in the file as triangle words.

How does one go about copying one binary FILE variable to another in C++? Say I have the following:
FILE* tempFile; //is a binary file and assume already filled with contents
FILE* localFile;
tempFile, as the name implies, is stored in a temporary directory (AND has a randomized temp name) within Windows and I want to copy its contents to another file with a predefined name that is within a valid local directory (e.g. C:UsersuserMy Documents est.exe). What do I have to use?
I am trying to code a function which will read a file on system and return its content back as string. Code is below.
char * readtxt(){
FILE * fptr;
char c;
static char txt[30];
int len=0;
fptr = fopen("C:UsersTestDesktopDev est.txt", "r");
[Code] ....
I suppose txt variable is pointer. But I need to return the file content as string so the function structure should look like
returnType function(){
return "File Contents as String";
}
How can I achieve this ?
