for i=1 to 3 for j=1 to i a=a+1 Next j Next i 执行上面的3重循环后,a的值为多少请问题目里的a是什么意思,求解过程

for(j=i+1;j SET TALK OFF CLEAR FOR I=1 TO 20 FOR J=1 TO 33 FOR K=(100-I*5-J*3)*3 IF I=J=K=100 I,J,K ENDIF ENDFOK=(100-I*5-J*3)*3 提示语法错误SET TALK OFFCLEARFOR I=1 TO 20FOR J=1 TO 33FOR K=(100-I*5-J*3)*3IF I=J=K=100I,J,KENDIFENDFORENDFORENDFORSET TALK ON For j = 10 To i + 1 Step -1 Dim x(3,5) As Integer For i = 1 To 3 For j = 1 To 5 x(i,j) = x(i - 1,j - 1) + i + j Next j Next iprint (3,4) Dim j%,i%,m% m = 0 For i = 1 To 3 For j = 1 To i m = m + j Next j,i Text1 = Str(m)最后m j 是多少 没有循环体的for语句结果是什么.for(i=3;i>=1;i--);{ for(j=1;j Private Sub Command1_Click() For i = 1 To 3 For j = i To 1 a = a + 1 Next j Next i Print a End Sub for(j=1;j for(j=1;j 为什么For i = 1 To 3 For j = 1 To i For k = j To 3 a = a + 1 Next k Next j Next i print a a = 0 For i = 1 To 3 For j = 1 To i For k = j To 3 a = a + 1 Next k Next j Next i Print aa = 0 For i = 1 To 3 For j = 1 To i For k = j To 3 a = a + 1 Next k Next j Next i Print a 这里循环了几次是怎样循环的 2个矩阵相加,For i = 1 To 4For j = 1 To 4c(i,j) = a(i,j) + b(i,j)Picture3.Print c(i,j);If i = 1 And j = 1 ThenMax = c(i,j)ElseIf Max < c(i,j) Then Max = c(i,j):n = i:m = jEnd IfNext jPicture3.PrintNext i这个和For i = 1 To 4For j = 1 To 4c(i,j) for( int i=0,j=1; j < 5; j+=3 ) i=i+j; 为什么等于5 Private Sub Command1_Click() For i = 1 To 3 For j = 1 To i For k = j To 3 a = a + 1 Next k Next j Na 的答案为什么是14 .是详细的 for (j=i Dim a%(3,3),i%,j% For i = 1 To 3 For j = 1 To 3 If j > land And i > 1 Then 中的j > land 含义为? J = 10 For I = 1 To J Step 5 I = I + 2 J = J - I Next I Print I Print J结果咋是15 和-3呢,要详细的哈,3Q3Q access 的for循环n=0for i=1 to 3 for j=5 to 1 step -1 n=n+1next j,idebug.print n;j;i根本看不懂啊,
