C :: Char Array Segmentation Fault
Jun 4, 2013i want to enter a URL in as a string, and extract just the URL part.
eg: Code: input: URL....
output: URL....
Input: URL....
output: URL....
part of our header file which we cannot edit (the url is always less than 140 characters):
Code:
char url[140];
function i am having problems with
Code: void init_url(char new_url[])
{
/*
This function sets the variable url to new_url and url_size to the number of characters in the url
It also initializes url_error_flag
}
[code]....
whenever i try a URL like the second one above with no '?' i'm getting a segmentation fault error which is becase i'm trying to access an invalid index. i'm not sure what an array is initialized to when i do not explicitly assign it anything, for example
Code:
char values[140] = {0};
i've read it depends on whether it is a global vs local array or something? i know this could all be fixed with simply assigning the array values to 0 but i'm not allowed to edit the header file.
C :: Storing Address Info Into Struct / Then Sorting It By Zip Code - Getting Segmentation Fault
May 10, 2014I need to take info in the following format (no blank/skipped lines):
last name, first name street address city, state zip code
And dynamically allocate space for it. I need to use structs, and I need to use an array of pointers to structs to point to them. I know I probably have quite a few problems with my code, but so far, I am able to store and print back the data without issue. In the following code, I only make the loop run 3 times just so I can test it with manual input into the console, but eventually the max will be 50, or until end of input (will be doing IO redirection with a txt file).
Like I said, I can store and print the data fine, but am getting a segmentation fault when trying to sort the info.
Code:
#include <stdio.h>#include <stdlib.h>
#include <string.h>
struct addressBook{
char name [50];
char streetAddress [50];

C :: Segmentation Fault When Replacing A Char In Array
Jan 25, 2013This function should replace all instances of a character in a given character array, while returning the amount of characters changed, but I keep getting a segmentation fault at the highlighted area.
I'm only supposed to use pointers so arrays are out of the question, and I don't think we are allowed to use the string.h library as well. How I could avoid something the segmentation fault or ways to fix it?
Code:
int replaceChars(char replace, char find, char *input) { int i, j;
//Finds length
for(i = 0; *(input + (i + 1)) != ' '; i++);
int c = 0;
for(j = 0; j <= i; j++) {
if(*(input + j) == find) {
*(input + j) = replace; //Segmentation fault happens here
c++;
} }
return c;
}
C :: Catch Segmentation Fault With GDB
Jan 23, 2013I am working on a distributed application in C. My program gives segmentation fault and aborts execution. But, when I try to run it through gdb, it keeps on running although without giving a useful output. I realize that I do not put much information in my query. But, what general causes could generate this behaviour. I am interested to find the cause of segmentation fault.

C++ :: Using Gdb To Detect Segmentation Fault In Sh?
Jan 16, 2015I am using scientific linux. In the directory user/project/Build, after I ran 'make' to compile and link all the cpp files,I had no problems. But then, when I went to directory user/run/run.sh, which runs the project binary in user/project/Build/bin/project, I get a segmentation fault error. In the directory user/run, I enter 'gdb' in the command prompt and get the message "*** No targets specified and no makefile found. Stop." What am I supposed to do to detect the segmentation fault?

C++ :: Segmentation Fault And Also Bad Initialization
Feb 25, 2012Code:
#include <sys/types.h>
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#define FILEPATH "./input.txt"
#define FILEPATH2 "./copy.txt"
[Code] ....
The problem is probably the fact that I'm using the variable s in the wrong way, but as I'm very bad at C and C++, at least so far anyway, I've no clue what's wrong. Is it my size that I passed in the marked method?
Also, how do I tell it, later, once this starts to work, to pass the file name of the file it'll copy to as the first param and the file it reads from to the pipe as the second param?
I'm supposed to be reading from a file, and as I was given some code, but it's probably in C and not C++, even if it is, I'm still not that great at C++ either, but anyway, I'm to have the program read from the file and write to the pipe and have the child read from the pipe and write to the output file.

C :: Segmentation Fault In Header File?
Apr 26, 2013I have written a small program for a class to convert decimal to binary and the program itself works, however, I am storing the binary bits in a stack that is in a header file (which I have used successfully before). It appears to push the bits to the stack just fine, however, when I use the printStack function I get a segmentation fault.
Here is the stack.h header file:
Code:
#include <stdlib.h>
#include <stdio.h>
struct stackNode {
int data;
struct stackNode *nextPtr;
[Code].....
And here is the main program that does the conversion:
Code:
#include <stdio.h>
#include "stack.h"
int binary (int x);
int main() {
int choice = 0;
printf("
[Code].....
One other thing of note, whenever I try to modify the printStack function, that function then seems to not work at all.
C :: Segmentation Fault At Free Call
Jul 7, 2014Code:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>
/* h(a)=abcab,h(b)=acabcb,h(c)=acbcacb */
void h_i(int i, char *w, char *a, char *b, char *c)
[Code] .....
Above program increases string like this example.
Let say h(0)=01 and h(1)=10 and let say our first string is w=0 h(w)=01, h^2(w)=0110 h^3(w)=01101001..etc.
We have used h map, which is given in the program comment statement. Same thing, program is doing for three letters. These three letters we have passed as argument in h_i function. e.g. h_i(2,w,"a","d","g") function will apply the 3 letter map h(definition is given in commented form in program) 2 times on string w.
In program w=a; and three letters are a, d and g. /* h(a)=abcab,h(b)=acabcb,h(c)=acbcacb */ here b=d and c=g.
Above program gives core dump at free(w2) free(w1). if we remove these free statements then it gives correct answer. But, we want to free w1 and w2 in the above code. How can we make free both w1 and w2 strings?
C :: Segmentation Fault Could Not Find After Debugging
Apr 15, 2013I want to know what was wrong with my code when I submitted. It's a Traveling Salesperson Problem, and the code is complete for the most part. I just can't seem to find what's causing the segmentation fault even after attempting to debug with gdb. Something is supposed to be wrong with line 76, but I don't see how my arrays are messing up. I've looked through this code countless times, and I know I'm just missing something small. I just don't want to end up making whatever mistake I made on this again in the future.

C :: Sscanf Causing Segmentation Fault
May 30, 2014I have a problem in my code and after hours of looking I really cannot find out what is the problem.I use scanf to to parse lines of a file, let me copy only the important part:
Code:
/*File read...everything is fine*/
int seq_1, seq_i2;
int len;
while(fgets(&line[strlen(line)], line_length, file)!= NULL) {
}
[code]....
if (num_sc ==4) //the wanted format, do something So I am allocating all variables, and giving to sscanf pointers, so I really don't get where the segmentation fault appears.I checked with the debugger, the first line of the file is read, but at the second it crashes at the line of sscanf! The two lines don't have the format I want in sscanf but therefore I check if this number is 4 and then do other stuff to the data...

C :: Segmentation Fault When Accessing Array
Aug 27, 2014Write a program that reads in the names and the ages of ten people. Store these data in two arrays (make sure that the entered names are not longer than the array size you choose). Then produce a table of ten lines, with each line giving the name and age of a person along with the (positive or negative) deviation of that person's age from the average age. The code I wrote to fill in the arrays looks as follows
Code:
#include<stdlib.h>
#include<stdio.h>
int main()
{ // begin main()
// array length
[Code]....
When I compile it, it gives me warnings that few of the variables I declared aren't used, but that is not affecting the program at all. When I run the program, it allows me to pass the names and ages into the arrays, but when it comes to displaying them, I'm getting a 'Segmentation fault'. I used very similar code in Java to write the program, and it worked fine so what is the problem with C then?
C++ :: Getting Segmentation Fault In Parser Code
Dec 23, 2014For some reason when i put cout<<endl i'm getting segmentation faults in my Parser code. It's really weird some inputs of strings using cout is already faulting. However sometimes printf doesn't fault, but sometimes it will, it seems really unstable.
