So this program I have to make keeps spitting out an error report when I try and run it. I am using eclipse C kepler.
The file it is supposed to read has the following text;
R1 N001 N003 20
R2 N002 N001 5
R3 N001 0 10
R4 N002 N003 10
R5 N003 N000 5
I1 0 N002 10
This is my problem. What should I do to be able to compile this program?

I actually think I see it now that I posted this. In operator= I'm changing the size, but I'm not changing the size of the array that it's pointing to correct? I'm keeping it as 'p = new T[size]' rather than changing it to 'p = new T[x.size]' correct?
#include <iostream>
#include "Array.h
int main() {

I just finished coding a program that is based on polymorphism and inheritance but when I ran the program it crashed? I do not know what is the cause of the program crashing.

#include<stdio.h>

I am able to add records and show records, no problem. But when I go to delete a record, it crashes immediately after inputting the record number I want to delete. I don't see why. I've set it up exactly like the example in my book, having of course changed the variable names for my program. Does it have something to do with the pointer?
When I go to run the Fibonacci function ( fib ), it begins to return incorrect calculations towards the higher numbers, but then seems to correct itself for a little bit, but then does it again and ultimately crashes. And the program seems to be crashing at random numbers. Sometimes the it will make it up to F(55), other times it will only get to F(20).
Also, when I go to run the program on a Linux server, it segfaults, but it doesn't when I just run it on my IDE. the function adds two arrays with individual digits together. It does this to allow the program to add numbers that would exceed the boundaries of INT_MAX.
Here is the header file "Fibonacci.h":
Code:
#ifndef __FIBONACCI_H
#define __FIBONACCI_H
typedef struct HugeInteger
{
// a dynamically allocated array to hold the digits of a huge integer
int *digits;
// the number of digits in the huge integer (approx. equal to array length)
int length;
} HugeInteger;
}

The program keeps on crashing when it finishes case 1
View 5 Replies View RelatedI was writing a program and it started crashing on exit (segment fault), after the 'return 0' in main(). I figure it's an std destructor.
I started with the program I was writing and just stripped out as much as I could, while making sure the crash persisted. If I remove any of the remaining code the crash disappears, even the seemly unrelated or scoped code.

I'm writing a code obfuscator in C. Debugger shows no errors in the code, but the program crashes after compiling -- I'm guessing it has something to do with while loops or reading data from files.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
// list off all replaced elements
typedef struct ReplaceList {
char *from;// from string
char *to;// to string (random)

How would I fscanf this piece of data?
Delimiter is --> :
VS1234567890654327:Rob Fordfirst:001:200
VS1234567890654312:Steven Harper:200:010

while(3==fscanf(filename, "????", &string[size], &name[size], &number1[size], &number2[size])) {
//printf("%s - %s - %.3d - %.3d", string[size], name[size], number1[size], number2[size]));
size++;
}
I am a very fresh c programme user, in fscanf data to arrays. Somehow it just doesn't gets recorded, wonder what is wrong with my code? When I printf the array it always ends up with random numbers.

I am trying to scan a list of 3 by 4 numbers and the 4 numbers of each column to the 4 different arrays, so if I read from the data above, i get an array with numbers 1,5,8; another with 2,6,9 and so on. Is it how its done in my code?

I need a way to count lines in a .dat file using fscanf. I must use a regex to check that the characters in the file are alphanumeric. In essence I need to count the ' ' character. I know fscanf ignores this character. I need to exit if it detects anything other than alphanumeric with the digit that is "problem" along with the line number. My .dat file is:
Code:
howard jim dave
joe
(
Maggie My fileCheck.c is: Code: #include "main.h"
int fileCheck(FILE *fp)
{
int ret_val;
int line_count = 0;
char file[BUFF];
[Code]...
The output I am getting is:
Code:
file opened Digit: ( is not an alphanumeric character on line: 5 Program will exit! File closed As you can see, the character "(" is not on the 5th line but the 3rd. It is the 5th "string."
I also wanted to show the regex I am using.
Code:
#define to_find "^[a-zA-Z0-9]+$"
How this can be accomplished?
I am trying to use fscanf to obtain a set of 14 or so strings per line, in a line where there are around 80 or so different sets of strings. I only need the first 14 and whenever I call scan f it starts at column 209 as opposed to column 1 where it should. Here's a sample of the code:
FILE *d;
d=fopen("t.dat","rb");
where a, n are all strings.
fscanf(d,"%s %s %s %s %s %s %s %s %s %s %s %s %s %s",&a,&b,&c,..(etc)..,&n);
A sample of the Input file looks like this:
USB270.15385-29.63146 270.153847 -29.631455 2.966699e+03 -9.99 1.300391e+03 -9.99 -9.99 A-A-- 6.787463e+01 -9.99 1.555773e+02 -9.99 -9.99 10100 | ----- ------ ------ ------ | 0.373 13.554 12.928 12.670 AAA | ----- -------- - -------- - -------- - -------- - | --- ---------- - ---------- - --------- - --------- - --------- - ---------- -
I added this snippet of code to a larger project I use to read some numbers in from a file, but for some reason I'm getting a segmentation fault.
Code:
printf("starting main

FILE *cutoffs;
double cut1=0, cut2=0, cut3=0;
printf("trying to open file
The cutoffs.in file looks something like
Code: 3.475 3.875 4.025
I ran the gdb debugger, so I know it is occurring at that fscanf; however, it doesn't give any other details (to be honest I don't have much experience with debuggers :x) ..The values are being put into an array. Before I just had numbers initialized in the array by hand, but need to have 20 different runs of this code with different numbers each time...
I am trying to make a program that will read in input in the following format:
| ...text... || ...more text... || ...still more text...|
i.e. every bit of "text" that gets read in is bracketed on either side by the "|" character.
The buffer that i read them into can be of a maximum length of 101 (100 characters plus a terminating null character); this is how I am currently reading in the input:
char readString [100 + 1];
while ( fscanf(infile, "|%1000[^|]|", readString) ){
/*... manipulate readString ...*/
}
How might I design this program so that, should any of the text appearing between the "|" characters exceed 100 in length, it exits and returns a warning?
