C語言字串排序示例

在C語言中，如何對字串進行排序？創建一個原始檔案：program_to_sort_string_characters.c，參考以下實現代碼 -

#include <stdio.h>
#include <string.h>

int main(void) {
    char string[] = "zaixiantoturials";
    char temp;

    int i, j;
    int n = strlen(string);

    printf("String before sorting - %s \n", string);

    for (i = 0; i < n - 1; i++) {
        for (j = i + 1; j < n; j++) {
            if (string[i] > string[j]) {
                temp = string[i];
                string[i] = string[j];
                string[j] = temp;
            }
        }
    }

    printf("String after sorting  - %s \n", string);
    return 0;
}

執行上面示例代碼，得到以下結果 -

String before sorting - zaixiantoturials
String after sorting  - aabiiiilorsttuy
