As soon as you said this: [quote] Could anyone tell me why this code read an extra line?[/quote] I immediately looked for this: [code] while (! in_stream.[COLOR="Red"]eof()[/COLOR]);[/code] This is a very common problem when testing eof() for an end of file condition. Instead try this: [CODE] //Test the return condition …

I would make 'name' a char array (cstring): [CODE] //line #7 char name[80]; [/CODE] Now you can actually accept a name from the user: [CODE] //Line #32 cout << "Enter ye' name: "; cin >> name; [/CODE] Since you are using cstrings (character arrays) you should become very familiar with …

From what I understand, an 'unsigned char' datatype will give you straight-up binary properties.. 8 bits, 1 byte, 0 to 255. [quote]My main task is to find a way of generating a boolean array of each character[/quote] I think a pseudo-code for the task at hand could be this: 1. …

I'm not sure what you are asking for, but I think you seem to be interested in preserving your white spaces. Try using getline(): [CODE] string line[50]; int pos = 0; int i=0; while(getline(datoteka, line[i])) { //Go back to the start of the line so you can extract data based …

One way I would approach this, is not to worry about templating the function at all until you get a function that does what you want it to do. Once you got that down, you can easily go back and do all the necessary templating. With that said, just concentrate …

After briefly looking at ye' code.. I would guess a displayPayment () would probably take place of everything going on between line #47 and #52.

A lot of people have questions about how to load a text file using file I/O. There seems to be 2 popular methods to loading a text file: Use fstream's >> extraction operator. Simple enough, load the file directly into individual containers, word at a time, but you lose your …

Try this and see if it works: [CODE] //Line #6 void getAge(int&); //Line #24 void getAge(int& years) [/CODE]

You want to return the min and max gpa from your binary search tree. Q. Is your tree sorted by gpa? If so, (if ascending order), your lowest gpa would be on the lowest far-left node. Conversely, your high gpa would be on the lowest far-right node. If BST is …

line #85, the name of one of your arguments is incorrect: [CODE] showArray1([COLOR="Red"]array1[/COLOR], SIZE); [/CODE] Also, just out of curiosity, why do you have two seperate functions to display an array.. it seems to me that one showArray() function could work for any array.

Anyone please feel free to chime in if you see anything wrong here: [CODE] //line #11 if(Temp -> Ch [COLOR="Red"][B]=[/B][/COLOR] CharToDelete) [/CODE]

[quote]it will say "scout arrived at 100,200" [/quote] After reviewing your loop, this seems to be the correct output in order to establish the terminating condition of your loop.. where toX == currentX AND toY == currentY... which will occur when toX becomes 100 (which is the initialized value of …

I agree with twomers, using cin seems to be a 'safer' method than using [URL="http://www.cplusplus.com/reference/iostream/istream/getline/"]getline(), [/URL]in that cin will (unless something wack happens) will read in the entire input buffer while use of getline() will extract everything except the '\n'.. leaving it behind to thwart your subsequent attempts of reading …

One thing I notice is that on line #48 you make this assignment: [CODE] b = a;[/CODE] and then on line #30 you totally undo the previous operation with each loop iteration: [CODE] b = start +i; [/CODE] So I'm not sure what you are trying to do, but something …

I believe that this may be related to your problem.. You are passing in objects to your functions 'by value' which necessitates the need to save a return value from your functions.

In my opinion, I think it's possible to decompile an .exe into a somewhat hackish assembly code.... where if a person has a lot of time on their hands, could do a translation from assembly to a higher level lanaguage. (which of course, would probably not even be close to …

Try using getline(cin, user_input); edit: went to go take a wiz, when I came back ya'll had the answers already.

You initialize all your string containers to 'white space' and your while() loop condition tests for 'white space' which will always test true (because at no time are they ever changed)
