I hot the following program from the book 'C++ For Dummies' but have two questions about it. First I compiled the program but I'm afraid to run because the memery created from the heap does not appear to me to get de-allocated. Am I correct in not wanting to run …

Consider the following code: #include<stdio.h> #define msizeof(type) ((char*)(&type) - (char*)(&type - 1)) int main() { int x; printf("%u %u\n", msizeof(x), sizeof(x)); return 0; } The Above code when compiled with g++ compiles just fine and works well without any wanrings, while in gcc it gives the following warning: `integer overflow …

I have several files to include from a subfolder and I just can't get this to work. I'm propably missing something here... The Makefile and .cpp with main function are located at /path/to/ and files to be included are at /path/to/src/buffer and /path/to/src/hash. Both of these folders have .cpp and …

Hi all, To begin, I'm not certain this is the proper place to start this question, but I believe this to be a linux-linker related error rather than a code based one. I've also searched far and wide for a solution online, but others have solved the problem simply include …

Hello everyone, I am working my way through the Forger's Win32 tutorial and am on the "Creating a Simple Application" part currently. I am using C++ (instead of C in the tutorial) and the WinGW compiler. When I compile the below code I get this error: main.cpp: In function 'LRESULT …

So, I just did a fresh install of ubuntu 11.10, and am in the process of reinstalling gsl. For some reason, my old make file seems not to work, and am trying to figure out how to change it. Last time I had a similar problem, people in here were …

Hey all! I was thinking about how to make a program, in which you write some c++ code and program tests that code with given examples. For example you input following code in that program: [CODE]#include <iostream> using namespace std; int main() { int a, b; cin >> a >> …

How do I do assembly code with the mingw-g++ compiler. All the websites I checked say that this should work: [CODE]int add(int a, int b) { int c=0; asm("mov %[aVal],%eax;add %[bVal],%eax;mov %eax,%[cVal]" : [cVal] "=i" (c) : [bVal] "i" (b) : [aVal] "i" (a)); return c; }[/CODE] But instead I …

I haven't coded something this complex in C++ before and I haven't had time to really review. I'm making a game (well, foundations for a game anyway), with an external game library, Allegro. But I think the problems I'm having is more fundamental to C++ in general. Included is a …

I'm using a cross-compiler that generates MIPS binaries from c++ (mipseb-linux-g++). What I want to do is tell the compiler to use a specific ISA (namely MIPS I). From what I can tell this is a machine option that should be easily configurable. I've tried changing the option in my …
