I'm pretty new to C++ and I'm on Binary Trees in "Jumping into C++"! I've just created a DLL project on Code::Blocks, and I cannot get it to build and run: "You must select a host application to "run" a library..." is the message that I'm getting when I run the main code file. It's had no changes to it (except for a few extra, unnecessary line feeds), and it's the file which Code::Blocks generates on a DLL project.

I'm trying to compile my project, but is not working, the weird thing is if i put all the code in 1 file it compile, but not in a project, source code:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#include <time.h>

I was trying to make boost's serialization use less bytes, and I stumbled upon this, which removes the big debugging symbols:
strip --strip-debug
or
strip -w -K '!*serialization*'
This seems like a working command on msys, but how to implement this into code blocks.
This has happened before, when I try to run a code it will say "blah.exe has stopped working" and I would have to change the code in some way to make it work.

In my c project in code blocks , I have added another source file (KillerMoves.c) and a header file under the same name (KillerMoves.h). I added the "include guard" to prevent double inclusion. But from some reason, the program suddenly crashes with no warning or specific error. Without the new files,the program runs without any problems. This is the source .c file:
Code:
#include "KillerMoves.h"
void initKillersTable(){
for(int i = 0; i < 15; i++){
killersTable[i] = -1;

I'm using Code:Blocks 12.11 on windows 7, with the built-in MinGW compiler. When I try and compile a program that has an error in it (misnamed variable, missing include, extra semi-colon somewhere, anything) instead of saying something about what went wrong it just has this:
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings (0 minutes, 0 seconds)
Which is not particularly useful for debugging.

I downloaded glew 1.9.0 files and dragged the lib, include, and bin of the glew into the mingw folder within Code Blocks. I don't know if this is the right thing to do I don't understand how this stuff works.

I am creating an application which will work as a static code analyzer after compiling my code in VS 2008 for VC++ projects. It will be a kind of code review.
how and where do I need to put my custom rule sets, and what should I do to create such a application.
I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)

I have a file that is like the following, with patterns of pipes in it:
Code:
||| || | |
| ||| | | |
|| || ||
I have to consider each row of pipe characters to be in blocks of 3 characters each (e.g. - positions 1-3, then 4-6, etc, etc...) but I have to capture all of the pipes, in sequence, like so:
positions 1-3 for lines 1-3, then positions 4-6 for lines 1-3, etc, etc...
How to get this done besides writing severely redundant control structures like loops, one after the other?
I have a file that I need to read in blocks. I need to read in n lines at a time, do some processing, and then read in the next block of n lines until the file is done. I know the size of the block, but not the number of lines in the file unless I check that first. Normally I would read in like,
Code:
// declarations
string new_input_line, input_file;
// create an input stream and open the input_file
ifstream input_file_istream;
input_file_istream.open( input_file.c_str() );
[Code] .....
// process through data_block
With this approach, I'm not sure how I would keep looping to read the next block until I hit the end of the file without knowing how many lines are in the input file. I could process the file to find that out, or get that number from bash and pass it it as an argument, but it seems like that shouldn't be necessary.
I could also read in and store the entire file as a vector of string and then process through it afterwords, but that would not be a very efficient use of memory.
Working on an assignment and I've hit TWO stumbling blocks. I now have to take the first line from a .txt file and use that number to determine the size of rows to create in my program. I am using fscanf but the program hangs. How can I read in this number, store it and use it in a for loop?
The second issue is after reading this number I have to print each number in the .txt file under a different column. (Note that it skips a line after reading the row count.) The .txt file is set up as follows:
9 1 3 6 4 7 8 8 6 1
The output should look sort of like:
Number 1 3 6 4 7 8 8 6 1
Here's my attempt:
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <math.h>
typedef struct{
int number;

I'm trying to keep track of the size of blocks of memory that a pointer points to. No matter what I do, this code below always outputs the integer 8.
If I change 1000 to 5, I still get 8. If I change it to 0, I get 8... If I change it to -1, I get 8. If I change int *a to double *a, I get 8. If I take away the & symbol, I get 8. If I use *& instead, I get 8.
Why? I want it to output 1000. If I change that to 500, I want it to output 500.
int *a;
a = malloc(1000 * sizeof(int));
int j = sizeof(&a);
printf("%d", j);
I want to build my skills where I can allocate, inspect and change memory sizes.
I have assignment which requires me to print out and array code and a pseudo code. I dont no what a pseudo code is,.
View 2 Replies View RelatedI have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.
However, Is designing a complete class just for a few functions over kill?
Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?
