假定有下面程序段 For i=1to3 For j=1 to i For k=j to 3 ...

假定有以下程序段 for i=1 to 3 for j=-4 to -1 n=n+1 next j next i 求最后 假定,以下程序段,n=0 for i=1 to 3 for j=4 to -1 n=n+i next j next i运 假定有以下程序段 n=0 for i=1to4 for j =3 to -1 step -1 n=n+1 next j 读下面程序：for i=1 to 3 for j=i to1 for k=j to 3 a=a+1 next k nex private sub command_click() for i=1 to4 x=3 for j=1to3 for k 下面程序段运行后 for i=1 to 5 for j=2 to i print"*";next j next i 为什 Sum=0 For1=1to3 Forj=i to 4 For k=j to 5 Sum=sum+1 Nex k Nex 假定有以下程序段n=0for i=1 to 3for j= -4 to -1n=n+1next jnext i运行完毕后 n=0,for i=1to3,for j=-4 to-1,n=n+1,next j,next i.运行完后n的值? vb读程序题：For i=1 to 3 For j=1 to i For k=j to 3 a=a+1 Next k,j vb题,For i=1 to 2 for j=1 to 2 for k=1 to j for i=1to4 x=1 for j=1to3 x=3 for k=1to2 x=x+6
