This program uses insertion sort to sort an array of integers. It prompts the user to enter the number of elements for the array, then collects the elements from the user. It then calls the inssort function, passing the array and size. The inssort function iterates through the array, inserting each element into the sorted portion by shifting greater elements to the right. It prints the array after each pass to show the sorting progress. After sorting, it prints the final sorted array.
