Final answer:
Selection sort is a simple sorting algorithm that repeatedly finds the minimum element and swaps it with the first element of the unsorted part of the array. The swap function in selection sort uses a temporary variable to hold one of the elements while swapping them.
Step-by-step explanation:
Selection Sort: Selection sort is a simple sorting algorithm that works by repeatedly finding the minimum element from the unsorted part of the array and swapping it with the first element of the unsorted part.
Swap Function: The swap function is responsible for swapping two elements in an array. To write the swap part of the code for selection sort, you can use a temporary variable to hold one of the elements while swapping them.
Here is an example of the swap function:
void swap(int* a, int* b) {
int temp = *a;
*a = *b;
*b = temp;
}
By calling this swap function, you can exchange two elements of an array by passing their addresses as arguments.
