You check the file size after you've already opened the file for writing. Since opening a file for writing creates an empty file with that name (overriding the existing file … -

The third is almost certainly the fastest (and the second the second fastest) as it only iterates over a third of the array (and the second over half). However this … -

Replied To a Post in break one char into two
As NathanOliver said, "t6" isn't a char, it's a char array. To get 't' and '6', you can simply access them as `"t6"[0]` and `"t6"[1]` respectively. -

You're only getting one occurence because you're only calling find once. If you use a while-loop instead of an if, you'll call it until it returns false, which will give … -
Replied To a Post in how do i write ....
Use an `if` to check whether you're in the last iteration (i.e. whether `i == x`). If you are, don't print a space after the number, otherwise do. -

"separated" means that the space should be between the numbers. Your code also adds one space after the last number, which is probably not allowed. -
