[code] int main() { Matrix A(2, 3); Matrix B(3); return 0; } [/code] >> Then does this create 2 separate matrices stored in data_? Yes it does. You have two distinct objects of type Matrix, they both withhold their own vector, so there is no interference between the two objects. …

[QUOTE=kangarooblood;1138635]well i do not want to use the system syntax, isn't there any other way to open a program in c++?[/QUOTE] No there isn't. You have to resort to OS specific functions to start programs.

It seems that the code uses [ICODE]getrusage()[/ICODE], which is not available on Windows.

It appears as if [code] total [COLOR="Red"]+=[/COLOR] weightcount(weight) + distancecount(distance); [/code] would do it. And also initialize [ICODE]total [/ICODE]to zero before entering the loop.

Are you sure you posted a relevant code snippet? The error message says: error: no matching function for call to ‘[B]merge[/B](vertex*&, int&, int&, int&) So there should be a call to [ICODE]merge(...)[/ICODE], but there isn't.

[code] Area::Area( int y, int x ) { for ( int i = 0; i != y*x; ++i ) { [COLOR="Red"] // the compiler sees the below line as a function declaration, // 't' is a function that takes no arguments and returns a Tile. [/COLOR] Tile t(); area_tiles.push_back(t); } …

[code] // First you have to do this for(for_loop_conditions) { free(charArray[i]); } // ... and then also this free(charArray); [/code] So there has to be a matching [ICODE]free()[/ICODE] for each [ICODE]malloc()[/ICODE] that you do. PS. Just to be clear ... if [ICODE]charArray[/ICODE] is also dynamically allocated, it needs to be …

Adding a note ... you are doing some out-of-bounds access there, for example [code] // two 'coord' objects, meaning // that you only can access indexes 0 and 1, nothing else. coord asteroid[2]; ... //Collision check for(int i = 0; i< 2; i++) { asteroid[i].collision(asteroid[i+1]); } [/code]

Something that looks suspicious ...

Then change [code] void Out(char* words) { …

[QUOTE=suncica2222;1135944] what is this (_CreateProcess) in the code??? is this a cast types?[/QUOTE] Yes it is a type cast. Why would you want be doing that kind of thing? You can simply call [ICODE]CreateProcess(...)[/ICODE] with the arguments it takes, without hassling with function pointers at all.

>> But i get error on push_back() while compiling. The [ICODE]alfadia[/ICODE] vector stores objects of type [ICODE]alfa[/ICODE], not pointers to such objects.

You probably want to start a new VS project that aims to build a library and add your work this far to that project. The very basic (simplified) scenario goes something like this ... The output of the project will be a library file (.lib) and optionally a [I]dynamic link[/I] …

Return a reference to the stream object, that's the way it has been designed to be done (the compiler complains about the streams copy constructor), so [code] ostream & operator<<(ostream &out, LinkedList list) { list.display(out); return out; [/code] Then furthermore, basically you want to pass class/struct objects by reference (or …

[QUOTE] Something is wrong with "dear_son"[/QUOTE] Yes, you do have room there for 5 children [code] dear_son = gcnew array<my_child^>(5); [/code] but they need also be given birth first, so [code] F.dear_son[0] = gcnew my_child; F.dear_son[0]->mas_1D[1] = 23; [/code] So there were no objects yet, only handles to such, hence …

I think that there is no protection against adding a ship several times to same location (neither for the user nor the computer). Then are you sure that you have gotten the usage of [ICODE]rand()[/ICODE] right, i.e. what does [ICODE](rand()%8)-1; [/ICODE] do? Then try to type in some unexpected input …

Sorry but the code you've posted is somewhat vague/insufficient. By looking at it, even the >> povbGarniture -> bInserer ((char) szTampon [n]); should fail.

A simple suggestion, perhaps try to see what ferror() says?

The [ICODE]<string>[/ICODE] header provides a global [URL="http://www.cplusplus.com/reference/string/getline/"]getline()[/URL] that does what you need i.e. it works with [ICODE]std::string[/ICODE]. For example [code] #include <string> #include <fstream> #include <iostream> int main() { std::ifstream ifs("file.txt"); std::string s; while(getline(ifs, s)) { std::cout << s << std::endl; } return 0; } [/code]

[QUOTE=newcuser;1131090]Here is what I have so far. Suggestions?? [/QUOTE] Compile the code and start working through the errors/warnings from top to down. Once you think you have solved/fixed a specific error, re-compile and see the results, i.e. don't try to fix all errors at once.

Use the [ICODE]extern[/ICODE] keyword to introduce the [I]variables[/I] inside the header (.h) files. [I]Define[/I] these [I]variables[/I] in their counterpart .cpp files.
