How to change directory in C program and retrieve files from a particular folder

Question

Hi,

I have an array of strings which contains the file names and I call a function in a loop.

char myFiles [20][50];

for(i=0;i<20;i++)
 myFunc( myFiles[i]);

The challenge I am facing is that, I have to store all the files in a directory, say "input" folder.... and then call

myFunc( myFiles[i]);

which I am unable to do.

I used mkdir("input"); to create a directory and moves all my files into it also using

system("move *.txt input");

But now if I give that path in my function it has to be hardcoded which eventually cannot be run in a loop.
ie

for(i=0;i<20;i++)
myFunc("C:\\input\\myFiles[i]"); //which is not possible....

I am using eclipse IDE.

Thanks in advance,
Faez

Solution 1

You can follow following steps in your loop

char FileName[1024] = {0};
for(i = 0; i<20;i++)
{
	sprintf(FileName,"C:\\input\\myFiles[%d]",i);
	myFunc(FileName);	
}

In this way you are able to create you file name dynamically.

This does not work.. I get a Win32 exception handling error
Moreover when I print "Filename" it prints as
C:\\input\\myFiles[0]
C:\\input\\myFiles[1] and so on...

I think his intention was something like
sprintf(FileName,"C:\\input\\%s", myFiles[i]);

Solution 2

I used the following

system("copy /input/*.txt  ");
/* After manipulations with the file..*/

system("del *.txt);
