If I have a file that looks like this. The date may also be 01/01/11 format and column 3 & 4 may contain whole numbers as well like 2, 3, 4 rounded to the whole number. How would I switch column 3 & 4 while leaving everything else alone?

In perl, read the line, use the split function (split at spaces) to split the line into array.  Print the line back
with elements 2 & 3 reversed (elements will be 0, 1, 2, and 3 ... 4 elements).
