C :: Random Number Game - Segmentation Fault (core Dumped) Error
Jun 25, 2013
Ok, so doing an assignment for a random number game where you guess and it says too high or too low until you get it right or run out of tries. Here is what I got so far:
Here is the code, and I can get it to compile successfully, but when I run the program, I get a "segmentation fault (core dumped)" error. I am guessing it might be related to a buffer overflow but I cannot say for sure.
Code: #include <stdio.h> typedef struc { int recordNo; char name[20]; int qty; float cost;
I am doing Histogram using pthreads and after long struggle on it.. finally it says 'Segmentation Fault (Core Dumped)'. I knew that error means something somewhere I am accessing to a wrong memory location.
It's compiling ok, and displays the first call to the printf function from main. However, after this I get the 'Segmentation fault (core dumped)' at the terminal, presumably from the call to the dictionarySort function.
I had a little look around and found it is something to do with non-existent or not available memory addressing, I think? Even so, I can't figure out what is causing the issue in my code.
{ int codice; char* nome; char* cognome; int esami; printf("Leggi uno studente da tastiera e memorizzalo in una struct "); lettura_studente(s1, codice, nome, cognome, esami); return 0; }
[code]....
In conclusion I'va two problems:
1) Program crash; 2) I can't read struct studente within parameter function. What are the problems?
I'm writing a code using least mean square to fit a sample of data. The code is running till an iteration where it crashes and returns a segmentation fault core dumped
(the memory used is always closed to 2g mem=1805804kb,vmem=1926132kb, seems like the code can't go beyond) .
But If i try to fit at this last iteration the code works perfectly, so i think that I'm not trying to access a variable at a wrong index but it might be dynamic memory allocation ( a pointer to a matrix that I didn't free or something like that). The code is complex and calls too many routines, I'm combining cimg , c++ and old c. How can I track this error?
It is been several days that I am stucked with the segmentation error and I do not know anymore what to do I try to do a loop over my function but it is working only for my first iteration. Here the code:
I would like to iterate over solvep (since h is changing at each iteration..I usually add other fct but now I try to debug why the loop is not working.).The first iteration is working fine but not the other iterations.
I'm writing a binary search tree program and I got it to compile but as soon as I input something it returns a "segmentation fault error" . I suspect the issue with the code is withing my `add` function.
template<typename T> void BinarySearchTree<T>::add(T value) { if (m_root == nullptr) { Node<T>* node = new Node<T>; node->setValue(value); m_root = node;
I'm working on a program that provides a number of utilities for strings, but I keep getting segmentation faults and I cannot tell why. strContains works fine, but basically the rest of my functions throw seg faults.
I have an error on my Guess the random number game.When you got the right answer it shows the "You got the right answer" and shows the "What is the number?" Here is the code.
Code:
#include<stdio.h> main() { srand(time(0)); int x=rand() % 101,guess=0,tries=3; printf("The computer will generate a random number, try and guess the random number. }
I am completely stuck when assigning values to and passing variables around. It seems that the problem occurs with fscanf function. I have also guessed that it might be passing and reading it as a character, even though I said it will be an integer, and tried atoi() with no luck. I troubleshooted the error as I tried to print the given values after I assign it. I am doing this for a friend I have recently been programming django, so I am completely out of the loop when it comes to C. where I am assigning converting passing in a wrong way?
#include <iostream> #include <stdlib.h> #include <time.h> using namespace std;
/* function main begins program execution */ int main() {
[Code] .....
I have gotten the conditions to execute properly but will end the program after doing a case instead of asking to play again and loop. Also how would i output the number of wins and losses?
The question for homework is Create an application that generates a random number in the range of 1 through 100 and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and then generate a new random number so the game can start over"
I have no errors in my code, but when it compiles it and I type the number in, and hit calculate nothing happens at all. Im baffled. Here is my code.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data;
I am recreating a hangman game. I'm trying to generate a random number to choose which word from my words list to use and I've done it a billion times before just like this. So, here's my code:
#include <iostream> #include <cstdlib> //standard library. #include <ctime> //for random. #include <fstream> //for reading and writing to a file. #include <string> using namespace std; int main() { int num_words; string word[num_words];
[Code] .....
I have the text file "words.txt" info below.
5 dog cat horse pig bird
If I run the program as it is, I get a segmentation fault core dumped error, however, if I take all the stuff that reads in the words from the words.txt file, like so:
#include <iostream> //every program has this. #include <cstdlib> //standard library. #include <ctime> //for random. #include <fstream> //for reading and writing to a file. #include <string>
Write a program that plays the game of guess the number.the program chooses the number to be guessed by choosing an integer at random in the range 1-1000. The program then types 'i have a number between 1 and 1000,can you guess number? Then the player then types the first guess, the program responds.
I 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.
I can't understand why my program keeps on getting "Segmentation Fault". The last time I checked (in UBUNTU) it was already working, now I'm testing it in Windows and I keep on getting "Segmentation Fault".
I 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?
I get the segmentation fault whenever it tries to insert the first player.. however whenever i do this :
void MakeSquad(char type, string name, int coordX, int coordY, char dir, int squad) { GameSpace::MapSquadType MapOfSquads; MapOfSquads.insert(make_pair(name , Squad(squad)); // Squad( int ) just converts the int squad number to the Enum. }
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.
I 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.
