关于for ……next语句内外循环的问题因为我不是很理解FOR NEXT循环语句的循环规则,所以麻烦大神详细解释一下每一步是怎么循环的好么?①private sub command1_click（）for i =1 to 4x=3for j = 1 to 3for k = 1 to 2x = x+3next knext jnext itxt1.value = str(x)end sub②private sub command1_click()dim i,j,xfor i = 1 to 20 step 2x= 0for j = i to 20 step 3x= x + 1next jnext itext1.value = str(x)end sub

①private sub command1_click（）
for i =1 to 4
x=3
for j = 1 to 3
for k = 1 to 2
x = x+3
next k
next j
next i
txt1.value = str(x)
end sub
②private sub command1_click()
dim i,j,x
for i = 1 to 20 step 2
x= 0
for j = i to 20 step 3
x= x + 1
next j
next i
text1.value = str(x)
end sub
