I'm trying to make a calculator that parses input like [TEX]( 3 + 2 ) * 5[/TEX] I want to use formal grammar for this, and I'm wondering how to organize this. I was thinking having a class for Value, which would basically just be a number. Then I want …

Hello! I'm just starting out with makefiles, and I'm doing something using SDL (it's a cross-platform window manager). For this project, I want to incorporate a makefile into it, but I don't know what to do. The tutorials for SDL say to compile the program, use this command: [CODE]g++ sdltest.cpp …

Hey guys, so I just started learning computational geometry, and I decided to make a class for a Point and a class for a Ray. This is my code: [CODE]#include <iostream> #include <string> using namespace std; class Point { public: double x, y; Point(double x, double y) { this->x = …

Hi, so I finally got around to looking into OOP in c++ and I have a question about classes. So I made this simple class: [CODE]#include <iostream> using namespace std; class Shape { int xPos, yPos; public: Shape(int x, int y) { xPos=x; yPos=y; } } ; int main() { …

I need a way to communicate with other exe's. Almost like being able to call cout but to a exe, not the output stream. Both of the apps would be in c++. I know cout is for output stream, sstream is for any stream, fstream is for files, something like …

Well for loops, there are 2 main loops. The first one is a "for" loop. Here is an example that prints the number 1-9: [code=c]for (int num=0;num<10;num++) { cout << num << endl; }[/code] The "for" keyword tells the compiler that you are entering a for loop. Then in the …

I am interested in using DirectX to make games. I'm using MinGW, which is a windows command line port of GCC. How would I get it so that DirectX 10 is included in the files? It probably is in the headers, but I don't know which to include because most …

I didn't know where to put this, so I'm putting it here and if any mod wants to move it them be my guest. I want to write my own ftp console application that would interpret the info and display it in a command-prompt like window. The only thing that …

I want to make a FTP client in C#. I know that C# already has a FTP class, but I want to make my own with a Socket as a learning tool. I understand that FTP uses port 21 and port 20, but I don't understand how to connect with …

I am learning assembly and I have a question about interrupts. Are they bound to a specific OS? I, like a lot of people, want to make a simple OS of my own, not that I ever will. I was wondering if I can use interrupts like 10h without having …

I need to pass a 2D array of int's into a function, which is normally fine, but the issue is that I don't know the last depth of the array. I know how to do it if I knew the length of the last dimension, but it is user defined. …

I have an array of strings, with each string being a name. I'm looking for a function that will find the index of a particular name in the array. I looked into Array::IndexOf, but my array is like this: [CODE]string names=new string[30];[/CODE] and it wont work. I could make my …

Thanks to another post of mine, I found out about itertools.product(). What I was wondering how to do is to code it so that I can use as many arrays as parameters as possible, with the number of arrays being defined by user input. for example, If the user inputted …

Doing what you are doing will make a list of each individual character, which is not what you want. To get an array of each line, use this: [CODE]lines=textfile.split('\n')[/CODE] Every time in the textfile it sees a new line (which is represented by "\n" in python) it will make a …

I need a way to get all the possible combonations of two lists. I looked into map(), but it only loops through the first array. I tried to do a map function inside a map function, but I couldnt figure out how. Heres an example: [CODE]>>> a=[1,2] >>> b=[3,4] >>> …

I am preparing for a programming competition soon and for one of the sample problems one line of input is the length of the list of numbers and the second line is the actual numbers. this is what i have: void main() { int num; cin >> num; int items[num]; …
