In this activity you will write the C code necessary for reversing a four digit integer. For example, if you have the integer 2101, the result should be 1012. Your final result should be held in a single variable (e.g., selecting out the individual digits is insufficient, you must also recombine them in reverse order). HINT 1: What position do each of the digits occupy?

HINT 2: Create four variables called ones, tens, hundreds, and thousands.

HINT 3: The modulus operator might be helpful for selecting the digits in the ones, tens, hundreds, and thousands positions (but you don't have to use it).
