【问题描述】
写一个函数，用冒泡法对输入的10个字符按由大到小顺序排列。需要编程过程。
#include <iostream>
using namespace std;
void BSort(char a[],int n)
{
for (int i = 0; i < n - 1; i++) {
for (int j = 0; j < n - i - 1; j++) {
if (a[j] < a[j + 1]) {
char t = a[j];
a[j] = a[j + 1];
a[j + 1] = t;
}
}
}
}
int main() {
char a[10] = {0};
cout<<"请输入10个字符:"<<endl;
for (int i = 0; i < 10; i++) {
cin >> a[i] ;
}
BSort(a,10);
for (int i = 0; i < 10; i++)
cout<< a[i]<<" ";
return 0;
}
下面是一个示例，说明如何在 C++ 中实现一个函数，该函数使用冒泡排序算法按降序对 10 个字符的数组进行排序：
#include <iostream>
// function to sort an array of 10 characters in descending order using the bubble sort algorithm
void bubbleSortDescending(char arr[]) {
// iterate through the array
for (int i = 0; i < 10; i++) {
// iterate through the array again, comparing each element to the one after it
for (int j = 0; j < 9-i; j++) {
// if the current element is less than the one after it, swap them
if (arr[j] < arr[j+1]) {
char temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}
}
int main() {
// initialize an array of characters
char arr[] = {'d', 'c', 'b', 'a', 'f', 'e', 'h', 'g', 'j', 'i'};
// sort the array in descending order
bubbleSortDescending(arr);
// print the sorted array
for (int i = 0; i < 10; i++) {
std::cout << arr[i] << " ";
}
return 0;
}
该程序将输出以下内容：
j i h g f e d c b a
