In C programming language, you can use the selection sort algorithm to sort an array. The basic idea of selection sort is to select the smallest (or largest) element from the unsorted portion each time and place it at the end of the sorted portion.<\/p>\n
Below is an example code of using the selection sort algorithm to sort an array of integers:<\/p>\n
#include <stdio.h><\/p>
void selectionSort(int arr[], int n) {<\/p>
int i, j, min_idx, temp;<\/p>
\/\/ \u904d\u5386\u6574\u4e2a\u6570\u7ec4<\/p>
for (i = 0; i < n - 1; i++) {<\/p>
\/\/ \u627e\u5230\u672a\u6392\u5e8f\u90e8\u5206\u7684\u6700\u5c0f\u5143\u7d20\u4f4d\u7f6e<\/p>
min_idx = i;<\/p>
for (j = i + 1; j < n; j++) {<\/p>
if (arr[j] < arr[min_idx])<\/p>
min_idx = j;<\/p>
}<\/p>
\/\/ \u5c06\u6700\u5c0f\u5143\u7d20\u4e0e\u5f53\u524d\u4f4d\u7f6e\u4ea4\u6362<\/p>
temp = arr[i];<\/p>
arr[i] = arr[min_idx];<\/p>
arr[min_idx] = temp;<\/p>
}<\/p>
}<\/p>
int main() {<\/p>
int arr[] = {64, 25, 12, 22, 11};<\/p>
int n = sizeof(arr) \/ sizeof(arr[0]);<\/p>
int i;<\/p>
printf(\"\u539f\u59cb\u6570\u7ec4\uff1a\");<\/p>
for (i = 0; i < n; i++)<\/p>
printf(\"%d \", arr[i]);<\/p>
selectionSort(arr, n);<\/p>
printf(\"\\n\u6392\u5e8f\u540e\u7684\u6570\u7ec4\uff1a\");<\/p>
for (i = 0; i < n; i++)<\/p>
printf(\"%d \", arr[i]);<\/p>
return 0;<\/p>
}<\/p><\/pre>\n
In the above code, the `selectionSort()` function is used to implement the selection sort algorithm. Within the `main()` function, an integer array `arr` is created, and the length of the array `n` is calculated. Then, the original array is outputted, and the `selectionSort()` function is called to sort the array. Finally, the sorted array is outputted.<\/p>\n
The code will produce:<\/p>\n
\u539f\u59cb\u6570\u7ec4\uff1a64 25 12 22 11<\/p>
\u6392\u5e8f\u540e\u7684\u6570\u7ec4\uff1a11 12 22 25 64<\/p><\/pre>\n
