in Bubble sort program, we call the bubble_sort(a,n) function which sorts the array. After calling the function , we print the elements of the array, so the sorted elements get printed. I wanted to know how the function is able to change the elements in the array in main() as the scope is different and we have learnt earlier that change of variable inside the function couldn’t change it’s value outside it.
Bubble sort execution
@himanshigupta579 Array is passed by reference which means that whatever changes which are being made in the bubble sort function will be reflected back in the main.
