arrar and copy files

[zyhsu1]

Dear sir:

I have a sequence image files: from box0001.jpg to box0015.jpg, I want to
cut box0001.jpg - box0009.jpg to a folder(C:/box1/), and cut box0011.jpg - box0015.jpg to another folder (C:/box2/), how do I use array and a loop to do this?

Can someone help? Thanks a lot!

Sincerely yours

For such purposes a script would be better than a program.
http://en.wikipedia.org/wiki/Batch_file
http://en.wikipedia.org/wiki/Shell_script

Anyway, in a for() loop you would use:
http://cplusplus.com/reference/cstdio/rename/
http://cplusplus.com/reference/cstdio/sprintf/

You need sprintf() to build the filename string from the current index in the for() loop.

Dear catfish3:
Sorry to bother you again,
If using program, how do I choose box0001.jpg to box0015.jpg by using
arrar, I dont want to write like this;
box[ ]={box0001.jpg, box0002.jpg,box0003.jpg....}
because the image files might be a lot??
I want to give a range, such as 1-15, or 16-200...etc
how do I make array by using the range?

Use the sprintf() function to create the arrays (not arrar, but array).

This is the traditional way (like how it can be done in C language, not just C++).

1 2 3 4 5 6 7 8 9 10 11 12 13 14

#include <cstdio> using namespace std; int main() { char tempFilename[100]; for (int i=1; i <= 14; ++i) { sprintf(tempFilename, "box%04d.jpg", i); printf("%s\n", tempFilename); } }

box0001.jpg box0002.jpg box0003.jpg box0004.jpg box0005.jpg box0006.jpg box0007.jpg box0008.jpg box0009.jpg box0010.jpg box0011.jpg box0012.jpg box0013.jpg box0014.jpg

The new way is by using string streams.

But I have to see your current source code (written program) to understand which way is better for you.
