I have the following code where I am trying to open a text file.
char frd[32]="word-list.txt";
FILE *rd=fopen(frd,"rb");
if(!rd)
std::cout<<"Coudn't open file\t"<<frd;
I am using vc 2010 and the file is in the debug directory of this project. Can anyone tell me why it is not able to open the file?
#include<stdio.h>
#include <errno.h>
int main()
{
errno = 0;
FILE *fb = fopen("/home/jeegar/filename","r");
if(fb==NULL)
printf("its null");
else
printf("working");
printf("Error %d \n", errno);
}
this way if fopen gets fail then it will set error number you can find those error number list at here http://pubs.opengroup.org/onlinepubs/009695399/functions/fopen.html
Look at the errno variable which is set in the event of an error. It's a global variable. It's been a while, but probably include errno.h which will give you the definition.
