my program is printing out a random symbol afterwards , when trying to copy a sequence of chars into a new buffer.
Code:
#include <stdio.h>#include <stdlib.h>
int tokenCopy(char* dest, const char* src, int destSize);
int main() {
char buff[3];
int n = tokenCopy(buff, "This is a string", 3);
printf("%d '%s'
", n, buff);

I am looking at one of the functions of an exercise:
void escape(char * s, char * t) {
int i, j;
i = j = 0;
while ( t[i] ) {
/* Translate the special character, if we have one */
switch( t[i] ) {
[code]...
Notice the while loop evaluates the current value in t to true or false. When we hit the null terminator, does that get evaluated as 0 and hence evaluates as a falsy value so the while loop exits?
So I have this program to calculate the types of meat, I have fixed the system errors but the actual program when I run it comes up with <null>
Code:

#include <stdlib.h>
#define beef 1 /* multiplication factor of beef*/
#define chicken 1.5 /*factor of chicken*/

I would like to know how can I make a simple program .exe so that I don't have to open it through code blocks every time.

Write a program that reads a sequence of positive integers and prints out their sum, except that if the same number occurs several times consecutively, ignore all but the first. Assume an input of 0 marks the end of the input. For example, if the input is 3 8 5 5 4 9 1 1 1 1 8 0 then you should print 38 (i.e., ignore one of the 5's and three of the 1's).

Lets say that I have that simple program:
Code:
#include <stdio.h>
int main() {
int x=1;
printf("x = %d", x);
return 0;
}
Code:
#include <stdio.h>
int main(){
double nc;
for (nc = 0; getchar() != EOF; ++nc)
;
printf("%.0f
", nc);
}
It works well and I am using ctrl-D as my EOF. Now I understand that C is not really a language for dealing with text, which is why I am learning it more in depth, my degree was in robotics, and I think C is definitely the best place to be for me. So this may just be a quirk, but if I type more than 10 characters, I get the right answer from the program, however, if I type less than 10, for the sake of argument I type Hello and then return, if I at that point do ctrl-D, I get the answer 6D?
The 6 is right 5 letters and a return character, but what is the D?
I'm trying to write a program that detects deadlock. Some of the code I already tested in an earlier stage but at this point when I run the code it somehow gets stuck. I believe that it has something to do with a negative integer value. Anyhow, the program should still work if a negative integer comes up. Here's my code so far.
Code:
#include <stdio.h>
#define FALSE 0
#define TRUE 1
int ALLOC[5][5], REQ[5][5], TOT_RES[5], process, resource, NUMB_RES=5, NUMB_PRO=5;
int TMP[5]={0}, AVAIL[5], CNTR=0, FIN[5]={FALSE}, FLAG;
}

The program usually gets stuck after producing output displaying the "Available: " text. After that a list of tabbed numbers should appear, but it doesn't.
I decided to create a simple program to display a menu with options, while that is easy enough I had some difficulty when selecting an option that has options inside which also has an option again. While I had many issues in the past I'm finally finished with it and it works fine, but being new to programming and not knowing various other methods available.

I have been working on a simple crc32 program in octave and have been using a program already done in C as a guideline. I have been having some problems since octave and C simply do things differently. Right now i have a problem with right shifting.
unsigned int crc = -85
unsigned int x = (crc >> 1);
The resulting x will be 2147483605. I tried putting 0xFFFFFFFF instead of -85 and i got the same result.
If i put -85 for crc in octave, i get a small number -43 which looks more reasonable.
The assignment is to write a program that statistically computes similarity of C syntax with another program; a same and a different. The one used here is in C language, it's called Battleship.cpp. The program must open a file and read line by line for keywords and then produce statistics. The reason my code is not running is the fopen function is failing and it goes to return -1. I am using MS Visual Studio 2013 and there are no compiler errors after turning off deprecation. I do see, however, this error UMEngx86.dll'. Cannot find or open the PDB file. The file being opened is in my source folder.

My program allows a server and a client to chat over a socket. Currently I have to wait for one of them to type a message and press enter, before a message from the other person can be received.
Is there a simple way for messages to be received instantly - but not disturb any message that is being typed in?
I have created a simple basic program that uses sockets but it can only handle one connection, how do I make it so it handles multiple connections?

I am trying to make a simple program for encrypting a char* with the XOR operator. The code compiles and links perfectly, but I get an Access violation runtime error:

Text that I am inputting:
My username is memberfunction.
Write a program to do simple encryption and decryption. Encryption basically means to convert the message into unreadable form. In this assignment, it should be done by replacing each letter of a message with a different letter of the alphabet which is three positions further in the alphabet. Then, all the letters will be reversed. Decryption is the process of converting encrypted message back into its original message. Your program should use the following shifting method.
Note: You must use array.
#include <iostream>
#include <string>
using namespace std;

The program will ask for the user to enter a value for x, then compute the following polynomial: 3x^5 + 2x^4 - 5x^3 - x^2 + 7x - 6.However, when I double check it with my calculator I get a wrong answer for random values of x. To simplify my problem I'm using only integers.

I am new to C programming, I have been given an assignment to create a simple calculator by splitting the program in 3 files. It should have 2 .c files and 1 .h... I went through the internet extensively and could only come up with this.

#include <conio.h>
#include "Functions.h"
int main() {
float x = 0, y = 0;
int operation;

float addition (float a, float b) {
return a + b;

#ifndef FUNCTIONS_H_INCLUDED
#define FUNCTIONS_H_INCLUDED
float Sum(float a, float b);
float difference (float a, float b);
float remainder (float a, float b);
float product (float a, float b);

HelI have been tasked with creating a program which (1) takes in integer values from a user (until the user enters -1) and inputs these values into a linked list. This (2)original list is then to be printed out. The program then uses the algorithm "bubble sort" to (3)order the list in descending order before finally printing it out again.
I have managed to do this but I kind of cheated since I do not quite understand how to manipulate a linked list. What did was I took the values in the linked list and transferred them into an array and then did bubble sort on that array.how to do bubble sort on a linked list as well as how to print a linked list.
Code:
#include<stdio.h>#include<stdlib.h>
typedef struct node
{
int info;
struct node *link;
}Node, *NodePointer;
void printList (NodePointer head)

For some reason I keep getting null pointers in most of my functions, and in my convertTime function the numbers are way higher than they should be.
Code:
//Utils.H header file----------------------------------------------
//This function takes the radius of a circle and returns the diameter, the circumference and the area.
int circleStatistics(double radius, double *diameter, double *circumference, double *area);
//This function takes a number of days and returns how many years, weeks and remaining days that is.
int convertTime(int days, int *y, int *w, int *d);
//This function takes a length of time and calculates the dilation of that time at a percentage of the speed of light.
int lorentzTimeDilation(double normalTime, double percentC, double *dilatedTime);

I am beginner in C++ programming. And i was try use STRTOK code with NULL fields, but in ARRAY fields NULL values is skiped. For example:
input text in Memo2:
AnsiString PAT02[100][20];
for (int IndexVRadku02 = 0; IndexVRadku02 < Memo2->Lines->Count ; IndexVRadku02++) {
AnsiString PNF02 = Memo2->Lines->Strings[IndexVRadku02];
char * PN02;

Array 00 01 02 03 04 05
00 0000 TEXT1 TEXT2

But i need this result:
Array 00 01 02 03 04 05
00 0000 TEXT1 TEXT2
01 0002 TEXT3 TEXT4 TEXT5
02 0003 TEXT6
I dont see any point of NULL in cstring. The code given below just outputs same as it would have done with NULL. My understanding is if size of char array is less than length of char array then null must be manually added?
#include <iostream>
using namespace std;
int main(){
char chr[0];
cin>>chr;//or if you use cin.getline;
cout<<chr<<endl;
return 0;
}
Enter something: hellowwwww
hellowwwww
Segmentation fault (core dumped)
why? for NULL char or something else?
In my raytracer-project I have the following function:
bool hitObjects(Ray &ray, std::vector<Object *> &objects, Vector3& normal, Material *mat) {
double tmin = K_HUGE_VALUE;
double t;
[Code]....
When I try to run this, I only get the message "Material pointer is null". So, somehow the pointer is null after the hitObjects-function is called, even though it isn't inside that function.
