double circulation 1. typical case: ask for less than 100 prime number. 2. take the elements on the diagonal of the matrix. 3. print "*" pattern.
procedure example:
Const, n=5, m=4
Dim a (m, n)
Private, Sub, Command 1_Click ()
K=1
For i=l To M
For j=l To n
A (I, J) =k
K=k+1
Next J
Next I
End Sub
Private, Sub, Command2_Click ()
Summ=0
For i=l To M
For j=l To n
If, i=l, Or, i=m, Then
Summ=summ+a (I, J)
Else
If, j=I, Or, j=n, Then
Summ=summ+a (I, J)
End If
End If
Next J
Next I
Print summ
End Sub
The process Commandl_Click () acts as a matrix in a two-dimensional array where 1 rows of N rows are stored in a, and the function of the process Comma, nd2_Click () is m (A) compute the sum and B of the elements of a circle on the periphery of a matrix) compute the sum of all elements other than one circle except the matrix
C) compute the sum and D of the first column and the last column of the matrix, compute the sum of the first and last elements of the matrix
