改正错误#include <stdlib.h> #include <time.h> #include <iostream.h> int N = 10; void BubbleSort(int a,int n); int main() { srand((unsigned int)time(0)); int a[N]={0}; int i; for(i=0;i<N;i++) a[i] = rand()%100; cout << "The Data Befor Sort:"<< endl; for(i=0;i<N;i++) cout << a[i] << "\t"; cout << endl; BubbleSort(a[N],N); cout << "The Data After Sort:"<< endl; for(i=0;i<=N;i++) cout << a[i] << "\t"; cout << endl; return 0; } void BubbleSort(int a,int n) { int i,k,t; int flag=0; i=0; while(i<n-1) { k = n-1; while(k>i) { if(a[k-1]>a[k]) { t = a[k-1]; a[k-1] = a[k]; a[k] = t; flag = 1; } k--; } i++; if(flag = 0) break; else flag = 0; } }

修改后的代码如下：

#include <cstdlib>
#include <ctime>
#include <iostream>

using namespace std;

const int N = 10;

void BubbleSort(int a[], int n);     

int main() {
    srand((unsigned int)time(0));
    int a[N] = {0};
    int i;
    for (i = 0; i < N; i++)
        a[i] = rand() % 100;
    cout << "The Data Before Sort:" << endl;
    for (i = 0; i < N; i++)
        cout << a[i] << "\t";
    cout << endl;
    BubbleSort(a, N);
    cout << "The Data After Sort:" << endl;
    for (i = 0; i < N; i++)
        cout << a[i] << "\t";
    cout << endl;
    return 0;
}  

void BubbleSort(int a[], int n) {
    int i, k, t;
    int flag = 0;
    i = 0;
    while (i < n - 1) {
        k = n - 1;
        while (k > i) {
            if (a[k - 1] > a[k]) {
                t = a[k - 1];
                a[k - 1] = a[k];
                a[k] = t;
                flag = 1;
            }
            k--;
        }
        i++;
        if (flag == 0)
            break;
        else
            flag = 0;
    }
}

主要的修改如下：

- 修改头文件，将 `stdlib.h` 和 `time.h` 改为 `cstdlib` 和 `ctime`。
- 修改命名空间，将 `iostream.h` 改为 `iostream`。
- 修改函数参数，将 `BubbleSort(int a, int n)` 改为 `BubbleSort(int a[], int n)`。
- 修改传参方式，将 `BubbleSort(a[N], N)` 改为 `BubbleSort(a, N)`。
- 修改比较符号，将 `if(flag = 0)` 改为 `if(flag == 0)`。
