Sum=0 For1=1to3 Forj=i to 4 For k=j to 5 Sum=sum+1 Nex k Nex sum=0 for i= 1 to 100 sum=sum+i next i print sum 我不懂为什么要SUM= 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 VFP编程 cleasum=0for i=1 to 10for j=1 to 10sum=sum+i+jj=j+2i=i dim i as integer dim sum as integer sum=0 for i=0 to 5 sum=s Sum = 0 n = 0 t = 1 For i = 1 To 100 Sum = Sum + t / n n = n #include main( ) { int k,sum=0 int count=0 for(k=1;k sum:=sum*10+(j mod 10) Private Sub Command1_Click() Dim b,k For k=1 to 6 b=23+k Nex 在以下编程中 sum=0; for (int k = 1; k 一个VBA程序段 sum = 0 n = 0 For i = 1 to 5 x = n/i n = n + 1 sum sum=sum*i/(2* i+1)和sum*=i/(2*i+1)的区别
