printf("Sorted data:\n");

}
这个程序哪里出错了求解！！
#include "stdafx.h"
#include <stdio.h>
#define N 10 //数组长度固定
void main()
{
int i, j, num, a[N];//
int change, t;
printf("Enter Number: ");
scanf("%d", &num);
printf("Enter Data: \n");
for (i = 0; i<num; i++)
scanf("%d", &a[i]);
for (i = num - 2, change = 1; i>0 && change; i--)//num-1
{
change = 0;
for (j = 0; j <= i; j++)
if (a[j]>a[j + 1])
{
t = a[j];
a[j] = a[j + 1];
a[j + 1] = t;
change = 1;
}
}
printf("Sorted data:\n");
for (i = 0; i<num; i++)
printf("%d ", a[i]);
printf("\n");
}追问
j+1<num-1
#include <stdio.h>
#define N 10 //数组长度固定
void main()
{
int i, j, num, a[N];//
int change, t;
printf("Enter Number: ");
scanf("%d", &num);
printf("Enter Data: \n");
for (i = 0; i<num; i++)
scanf("%d", &a[i]);
for (i = num - 2, change = 1; i>0 && change; i--)//num-1
{
change = 0;
for (j = 0; j <= i; j++)
if (a[j]>a[j + 1])
{
t = a[j];
a[j] = a[j + 1];
a[j + 1] = t;
change = 1;
}
}
printf("Sorted data:\n");
for (i = 0; i<num; i++)
printf("%d ", a[i]);
printf("\n");
}追问
为什么第十三行是num-2呢
追答 (a[j]>a[j + 1])->j+1<num-1

int i,j,num;
int change,t;
printf("Enter Number: ");
scanf("%d",&num);
int *a=new int[num];
前面几句改一下试试

printf("Enter Number: ");
scanf("%d",&num);
int *a=new int[num];
