I've heard that the advantage of java is that people can write code, compile it for the JVM, and run it anywhere. Each person just needs a JVM app for their platform. Of course, it looks similar to the current situation, where everybody has a compiler specific for their platform. So the advantage isn't explained by that. But I think I...

When two vowels come one after another then the count should increment.But i dont know why its incrementing it more than that. #include<stdio.h> #include<conio.h> void main(void) { int i,j,count=0; char string[80]; printf("Enter a string:\n"); gets(string); for(i=0; ;i++) { if(string[i]=='\0') ...
Possible Duplicate: multiplication of large numbers, how to catch overflow In close to the metal languages like C, C++ and D, what's the most efficient reasonably portable way (i.e. w/o using assembler, though you may assume two's complement arithmetic and wrap-around behavior) to detect overflow of an unsigned 64-bit integer ...
Possible Duplicate: Whats the best way to become familiar with a large codebase? Dear fellow C and C++ programmers, today I got my hands on a new base of code which is around 800,000 lines of code (C and C++ mixed). How do I get familiar with such a huge code? What code browsing tools do you suggest? So far I found only MXR (...
Hello I'm using c++ with embedded SQL trying to receive command line arguments as SQL statements. For instance I want to be able to do: ./a.out proceedings(foo#bar) and tokenize the argument into: proceedings, foo, and bar with #, (, and ) as delimiters. Anyways, I was just wondering if there is a way to use brackets in the argument ...
When compiled by gcc and then run, the code int *p; int main() {*p = 1;} causes a segmentation fault. Apparently, the memory location contained in p cannot be written to. Why???? On the other hand, int q[]; int main() {*q = 1;} runs just fine. What's going on here?? Why does p contain only read-only memory?...
#include <stdio.h> int main(int argc, char** argv) { void (*p) (void); /* this obviously won't work, but what string could I put in here (if anything) to make this execute something meaningful? Does any OS allow instructions to be read from the stack rather than text area of the process image? */ char *...
My objective is conceptually simple: I want to set a GetMessage global hook function that utilizes a shared file handle. The problem arises because to my understanding the DLL containing the hook function is loaded multiple times for each process, each with their own "address space". For this reason I'm led to believe I can't simply hand...

I am confused when should I add the trailing _t to typedef'ed types? For example, should I do this: typedef struct image image_t; or this: typedef struct image image; What are the general rules? Another example, should I do this: typdef enum { ARRAY_CLOSED, ARRAY_OPEN, ARRAY_HALFOPEN } array_type_t; or this: typdef enum { ARR...
I have written my own linked list implementation in C, and it works fine for storing values, but whenever I try to run through the list I get a segmentation fault. I'm not sure why the issue arises, and I spent a decent amount of time trying to run through the program myself but to no avail. Could you guys help me find the reason for the...

I'm trying to figure out an algorithm which can look at raw rgba pixels and return points that make up the polygon of the object inside example: http://img706.imageshack.us/i/polii.png// It doesn't have to return bezier curves or anything smooth or fancy, nor a connected outline as I showed, but basically the points to build such an ou...
I'm looking for a way to make my application produce smoother results in freehand mode. Right now it simply adds each mousemove points and makes a polygon out of this. I noticed modern vector applications produce bezier curves to make it look much smoother and im wondering how this is done? So how can I get the 4 points to do bezier inte...
