Hi all, I was looking for a free C Compiler. Can you please help me out ?? I have Microsoft Visual Studio installed on my system. But I dont think they have a C compiler. Cheers, Shalini

this programme from sedgewick's 'algorithms in c parts 1-4' "is a sample client program that ... uses a symbol table to find the distinct values in a sequence of keys (randomly generated or read from standard input), then prints them out in sorted order." #include <stdio.h> #include <stdlib.h> #include "item.h" #include "st.h"

Hello, I have a question about portability and I have not found the answer in the FAQ. I have different modules to build. All of them have the same private part and a common public part (though the implementation in all cases may be different). Note that I already have implemented a similar idea and that it works pretty well with my gcc but...

Hello, All! I started to implement simple command line interface (CLI), and wanna know how to use table of fucntion calls. Could you please, recommend me some link or give example directly in conference? Thanks in advance! With best regards, Roman Mashak. E-mail: mrv@tusur.ru

Hello, Is there a possibility to initiate an array with more types, say int's and char's? I think it is possible to dynamically make a multi dimensional array, and then typecast the return value of malloc() function: int **array = (int **)malloc(ROWS * sizeof(int *)); for(i = 0; i < ROWS; i++) array = (int *)malloc(sizeof(int));

Hello, I'm a newbie who hopes they have come to the correct place. Basically, I want to develop a web service for consumption by .NET program (hopefully C#). The performance of the service would have to be able to be very fast in response and be somewhat reliable (i.e. not abending every 2 or 3 minutes). I was going to try to develop...

Hi, The ISO-C++ spec says that the order of construction for C++ objects is: **************************************************************** .... Initialization shall proceed in the following order: * First, and only for the constructor of the most derived class as

I am tring to understand the purpose of b-trees and concept that drives the construction of a b-tree. Are there alternatives to the b-tree? No need to answer such a question if you don't like the conceptial aspects of c ++ algorithms... :-)

Hi, Having problem with boost and stuck. I have the following: std::map <std::string, boost::anybinaryHeader; and somewere else I write: --------------- binaryHeader.insert(make_pair("job", 0));

Given the following code include <stdio.h> #include <stdlib.h> int main(void) { char *msg_list = {" apple", " orange", " grape" }; printf("name: %s \n", msg_list);

the ______ keyword is used in a fuction header to indicate that a function does not return a value or to indicate that a function cotains no parameters

Hi, I am trying to make sense of this endian problem and so far, it is still Greek to me. I am have some files that have stored lat and lon data in binary format. The data was originally floats (32) and written in with the most significant byte in the lowest address (big endian). I have an Intel processor and working in Mandrake. In...

Hey, I'm having some trouble with a program I'm trying to write and was hoping someone here could help me. Basically I have a dynamic 2D array of the 'Square' class and in the square class is the pointer 'item.' 'item' is a pointer of another class that I have called 'Inhabitant' and I have 3 derived classes off of 'Inhabitant.' I need to somehow...

How do I get uniform random numbers in the log domain? I need a random number in the log domain between -infinity and -0.69314718, which is equivalent to a range from 0 to 0.5. I usually use this code to get a uniform random number between, say, 0 and 0.5: double r = lowest + range * rand() / (RAND_MAX + 1.0); But it won't work in the...

Hi, I would like use a socket for write a file jpeg on the network. In others words, it is possible to publish a jpeg (like a streamer) that a client can fetch and view? file JPEG -socket that publish this file on the network -client (browser) fetch this file and show I.E. I think that firefox show a file jpeg also if this change...

In debug mode I am not able to trace the integers. The code is given below: int m = 10; float H = 1.90; printf("%d %f\n",m,H); ... ... In debug watch window, the value shown for m is ' 0x00000064 ' and for H is 1.900000. But on screen both the values turn out to be correct. This is the case with rest of the integers in the code. What...

I am thinking of doing a project along with learning more about c++. I plan on making a Meal Planner program. I have seen a few but they look like they were down in Visual Basics though they were written in c++. So my question is if I want my program to be user friendly in the end like those how do I go about it? Can I program it first then add...

Hi all, Many users claim that malloc() and free() provided by the language library results in considerable amount of overhead in terms of calling the same. Can we really eliminate overhead by using used defined functions/user defined memory manager. Is there any significant advantage in providing user defined malloc() and free(). I want...
