[quote][code]vector<MyClass> MyVector; MyVector.push_back(MyClass(Param1, Param2, Parm3, Param4));[/code] As I understand this would involve creating two instances of the object and copying one to the other. Is that correct?[/quote] As I see it, you are creating one instance of 'myclass' which pushed into the vector. [quote] Would it run quicker if I …

I wish you luck on your endeavors.

You appear to be lost and overwhelmed held captive in a class that probably has no relevance whatsoever to your degree major. What you need is a strategy to tackle this seemingly overwhelming task. If you look at this thing in it's entirety, yes.. it does look like some intense …

Why ruin a good thing you already got goin'? [CODE] //this gets(employee[counter].name); //should be this cin >> employee[counter].name;[/CODE] I am really not sure where you got "gets()" from.. I think it's a C function... and if I'm not mistaken it's use can be somewhat dangerous. In my opinion, it is …

would this be anything close to what you need...? [CODE] void TicTacToe::postMove(int row, int col, char value) { theboard[row][col] = value; showBoard(); }[/CODE]

This one is pretty decent: [url]http://www.codeblocks.org/[/url] Not as easy as it used to be.. you could easily start a 'project' as opposed to a 'c++ source' which will mess things up. The debugger is kinda wack. Also, it forces you to save work you haven't even created yet. If you …

After briefly looking at your code.. maybe all it needs is just a space in between commands: [CODE] //this strcpy(str, "taskkill /f /im"); //might work if it was like this: strcpy(str, " taskkill /f /im");[/CODE]

Move on through your C++ at a rate at which you understand the material (for the most part) and then begin to tackle the next concept.

I would be more than happy to help you.. however, I cannot read a bit of that antiquated C code that you have posted in this C++ forum...

Here is recent help given to one of your classmates: [url]http://www.daniweb.com/forums/post1070744.html#post1070744[/url]

You seem to have mentioned that you have attepted to make some sort of effort at seeking a solution to the problem. I'm sure myself and others would be highly interested in seeing what you have come up with thus far; thereby seperating yourself from the masses of "please do …

You seem interested in reading in a file until you reach a delimeting comma. In this case, I recommend use of [URL="http://www.cplusplus.com/reference/string/getline/"]getline()[/URL]. There are a few different getline() functions floating around in the c++ world. The one we are using (and most popular in file i/o) is derived from the …

I will offer few improvements to your code and propose a possible pseudo-coded solution to your initial question. Firstly, reading in an entire file character at a time is inefficient should be avoided. There may be some situations where this approach may be warranted; however, I believe that this isn't …

I think the problem is here... [CODE]for (int i=-1;ip!=" ";[COLOR="Red"]i--[/COLOR])[/CODE] Since you are using the 'end' flag in seekg(), all offset is relevent to the end of the file.. therefore, you should increment your way from the end of the file, stepping your way backwards into the text file.

Today we'll be creating an 'ostringstream' object derived from the <sstream> library in order to facilitate our int-to-string needs: [CODE] #include<sstream> #include<string> #include<iostream> using namespace std; int main() { ostringstream int_to_str; string temp; int a = 0; cout << …

FirstPerson... I think the OP asked for a nested for loop :P

What you are asking for can be a very useful data structure... if created dynamically can have about the same performance as a vector and might even be more efficient (a vector might allocate more memory than what you actually need based on the number of push_back() opearations) In either …

Unfortunately in c++, there is really no good way go locate lines in your file without reading the entire file 'character at a time.' So, if you [I]have[/I] to read only a single line from a file, we know we are at some point going to have to be inefficient... …

try this string parsing algorithm to split your line up into individual strings: [CODE] #include<string> #include<vector> int prev = 0; int curr = 0; string temp; string line = "The man is 67 years old and driving an Oldsmobile Rocket 88"; vector<string> vstring; do{ prev = curr; curr = line.find(' …

right now all that I see that might cause stack overflow might be this.. [CODE] std::vector<BaseEntity> BaseEntity::sm_vEntities = std::vector<BaseEntity>(100000); [/CODE]

Does anyone understand this...? or is it just me...

I imagine this would require some sort of DLL injection.. where applications would send messages back to your program about their status, specifically if they have the input focus.. window is active or minimized. I believe the last chapter of "Advanced Windows" by Jeffrey Richter covers dll injection, reading and …

People always ask, "Why do you always have to initialize your variables?" This is why: [CODE] //Here you create something.

Do you mean like this? [CODE] str1 += str2; str1 += str3; str1 += str4; str1 += str5; cout << str1; [/CODE]

I think it looks really good.. best I've seen in awhile.

The recommended scheme for File I/O is to create an fstream object, attempt to open a file, perform error checking, and load the file. The code in question is performing error checking to see if the file was actually opened. It is quite possible that the file may have been …

Although I am not an inheritance expert, I have a feeling your inputInfo() outputInfo() functions of your [U]parent class[/U] need to be labeled 'virtual' because they are overridden in the child class.

try making this small adjustment to your 'while' loop condition: [CODE] while((score < 0 || score > 100) && (score != -999)); [/CODE]

By doing this, you have established a direct relationship between the two arrays: [CODE] //We can assume that 'votes[3]' corrosponds to 'candidates[3]', for example. if ( inFile >> candidates[i] >> votes[i] ) [/CODE] So all you really need to do is extract the largest value from the votes[] array: [CODE] …
