sum=0 for i= 1 to 100 sum=sum+i next i print sum 我不懂为什么要SUM=0又SUM=SUM+i 详

sum=0 for i= 1 to 100 sum=sum+i next i print sum 我不懂为什么要SUM=0又SUM=SUM+i 详 dim i as integer dim sum as integer sum=0 for i=0 to 5 sum=sum+i next sum=? VB中的Dim sum As Integer语句Dim sum As Integersum = 0For i = 1 To 20sum = sum + ii = i + 1Next iPrint sum=; sum是怎么计算的 计算结果是多少 为什么我的MATLAB,for程序只运行一次加和 sum=0; for i=2;10 sum=sum+i end ans = 10 sum = 2sum=0;for i=2;10sum=sum+iendans =10sum =2sum=0;for i=2;10sum=sum+iendans =10sum =2 VFP编程 cleasum=0for i=1 to 10for j=1 to 10sum=sum+i+jj=j+2i=i+3endforendforsumretu 一下程序段运行后,变量sum的值是sum=0i=0For i=2 To 10 Step 2sum=sum+iNext i怎么算的,列数学算式给我. int sum=0; for( int i=1; i SUM=1+1/2!+1/3!…+1/10!之值CLEAR sum=0 for i=1 to 10 s=1 for j=1 to i s=s*j endfor sum=sum+1/S endfor?1+1/2!+1/3!…+1/10!=,sum初学VF 问题有21：VF中的 ! 代表什么意思?2：for j=1 to i s=s*j 这句是什么意思?谢谢for j VB编程题：统计7*7数组四周元素之和及四周元素中能够被7整除的元素的个数,并在标签中显示.Sum = 0For i = 1 To 7Sum = Sum + a(1,i)Next iFor i = 1 To 7Sum = Sum + a(7,i)Next iFor i = 2 To 6Sum = Sum + a(i,1)Next iFor i = Sum = 0 n = 0 t = 1 For i = 1 To 100 Sum = Sum + t / n n = n + 1 t = -t Next i 结果除数为0Sum = 0n = 0t = 1For i = 1 To 100Sum = Sum + t / nn = n + 1t = -tNext i 结果出现除数为0的情况 请问哪里错了? 阅读下面的程序段sum=0fori=1 to 3for j =i to 4for k =j to 5sum=sum+1next knext jnext i执行上面三重循环后,SUM的值为 怎么用lingo求解多目标规划呢,max =@sum(I(i):@sum(J(j):@sum(link(I,J):x(i)*w(j)*p(i,j)/d(i,j))));@for(I(i):@sum(J(j)|w(j)#eq#1:x(i)*p(i,j))>0);@for(I(i):@sum(J(j):x(i)*p(i,j)*c(j))>0);@for(J(j):@sum(link(I,J):x(i)*p(i,j)>=0));@for(l for(int i=0,sum=0;i ,year,sum,leap;for(i=0;i VB编程 Dim sum As Double,x As Double sum = 0 x = 0 For i = 1 To 5 x = n / i n=n+1 sum=sum+x nextprint结果为,sum 为什么结果是1/2+2/3+3/4+4/5而不是1+1/2+2/3+3/4+4/5 #include void main() { int i;int sum=0; for(i=1;i VB要求常数表达式Private Sub Command1_Click()Dim mark%(), i%, n%, sum!, aver!n = InputBox(输入人数)Dim mark(n - 1)For i = 0 To n - 1 mark(i) = InputBox(输入成绩¨) sum = sum + mark(i)aver = sum / nMsgBox (平均成绩 + Str(aver Sum=0 For1=1to3 Forj=i to 4 For k=j to 5 Sum=sum+1 Nex k Next j Next i 执行上面的三重循环sum的值?怎么看哪儿是内循环?哪儿是外循环?
