i am begginer at c programming and i wrote program and trying to run my program via terminal
from terminal:
$ ./Countries 2 /home/david/CLionProjects/untitled/dddd.txt
i get the error:
message: Segmentation fault (core dumped)
but when i run my program with my Clion its work perfectly.
i tried to debug with dbg and i found the error:
Program received signal SIGSEGV, Segmentation fault.
_IO_fgets (buf=0x7fffffffdc00 "", n=300, fp=0x0) at iofgets.c:47
47 iofgets.c: No such file or directory.
its seems that my program cant read the file dddd.txt and i cant understand why .
my main:
#include <stdio.h>
#include "Countries.h"
#include "Countries.c"
#include <string.h>
int main(int argc, char *argv) {
{
int fortest= atoi(argv[1]); //number of Countries
char *useForString; // use us to points to string use like name of country or city or food
int incrementCountry = -1;// increment every time when enter country from input
FILE *fp = fopen(argv[2], "r");
int chooseOfclient; //input from client number between 1-6
char singLine[300]; //char array for the line from text
Country **Atlas = buildCountry(fortest); //build Countries arraywhile ((ch != 'n') && (ch != EOF))
while (fgets(singLine, sizeof(singLine), fp))
{//while1
if (singLine[0] != 't') {//if
incrementCountry++;
useForString = cutNameOfcountry(singLine);
Atlas[incrementCountry] = inputNewCountry(useForString, cutCordiantesLeft(singLine),
cutCordiantesRight(singLine));
free(useForString); // free the memory from heap that allocate inside cutNameOfCountr
continue;
}//if
City *pCity = cutCityData(singLine);
buildCity(Atlas[incrementCountry], pCity);
}//while
return (0)
}

It seems that the problem is related tofgets()receivingNULLas pointer to file (fp=0x00 in the error), so check the result offopen()withperror(), also#include <stdlib.h> if you are usingfree()

yeah , this is the problem : Error: : No such file or directory Segmentation fault (core dumped) idea how can i fix it?

Have you checked the result ofperror("fopen")? "No such file" is pretty descriptive :P

Nov 17 '18 at 7:13
i added if after the line FILE *fp = fopen(argv[2], "r"); if(fp==NULL) perror("Error: "); and than tried to execute again and got : Error : No such file or directory but if build and run my program via Clion , its work perfectly
