Confused about a problem on exchanging an array

[cppnewguy]

here is the question from my teacher, i'm not sure how to get started on this:

"Consider the following sort procedure written in pseudo code:

Exchange Sort of Array X[]

For I = 0 to (number of array elements - 2), increment by 1
For J = (I + 1) to (number of array elements - 1), increment by 1
If X[I] is greater than X[J] then
swap X[I] and X[J]
Next J
Next I

Implement the sort procedure in main() without using pointers.
Declare the array as follows using the test data shown:
int x[] = { 28, 87, -3, 45, 19 };
Use a for loop to print out the array before sorting and again after sorting."

Start with creating the array and iterate through it

It seems that this algorithm is the selection sort but with numerous swap operations.
