8.6 String Selection Sort
Modify the selectionSort function presented in this chapter so it
sorts an array of strings
instead of an array of integers. Test the function with a driver

Answer 1

To modify the selection sort algorithm for strings in C++, you need to compare string values using lexicographical comparison and swap strings to sort them. An implementation includes iterating through the array, finding the smallest string, and swapping it into the correct position.

Step-by-step explanation:

Modifying the Selection Sort Algorithm for Strings in C++

To modify the selection sort algorithm to sort an array of strings, we will need to compare string values instead of integers. In C++, strings can be compared using the standard relational operators. The main idea behind the selection sort algorithm is to find the smallest (or largest) element from an unsorted segment and swap it with the first unsorted element. We execute this process repeatedly until the entire array is sorted.

Here is a step-by-step guide to modifying the selection sort for strings:

Hee is an example how to implement a selection sort function for an array of strings in C++:

void selectionSort(std::string arr[], int n) {
for (int i = 0; i < n - 1; i++) {
int minIndex = i;
for (int j = i + 1; j < n; j++) {
if (arr[j] < arr[minIndex]) {
minIndex = j;
}
}
std::swap(arr[i], arr[minIndex]);
}
}

To test the function, you could create a driver program that initializes an array of strings, calls the selectionSort function, and then prints the sorted array to verify the correct order.
