下列程序的运行结果是____.

我的思路是①j=i=0,a[0]=a[0]+1=2,a[1]=2,a[2]=2,a[3]=2,a[4]=2

②i=1,j=i=1,a[1]=a[1]+1=3,a[2]=3,a[3]=3,a[4]=3

……这样子依次算下去,然后a[1]=3,a[2]=4,a[3]=5,a[4]=6

但是答案是4,6,8,10

i = 0

a[0] = a[0] +1 =2, a[1] = a[0] +1 =3, a[2] = a[0] +1 =3, a[3] = a[0] +1 =3, a[4] = a[0] +1 =3

i = 1

a[1] = a[1] +1 =4, a[2] = a[1] +1 =5, a[3] = a[1] +1 =5, a[4] = a[1] +1 =5

i = 2

a[2] = a[2] +1 =6, a[3] = a[2] +1 =7, a[4] = a[2] +1 =7

i = 3

a[3] = a[3] +1 =8, a[4] = a[3] +1 =9

i = 4

a[4] = a[3] +1 =10

输出 4  6  8  10
