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是赋初值,也就是说对sum这个变量赋于初值.然后再将sum的结果累加!就好像：
1+2+3+4+5.100
=3(这里的3就是1+2的结果)+3+4+5+.100
=6（同上）+4+5+.100
=10(同上)+5+.100
这样子一样!

sum=0 for i= 1 to 100 sum=sum+i next i print sum 我不懂为什么要SUM= sum=sum+i^2什么意思 sum+=i是什么意思 i = i * sign; sum = sum + i ; sign = -sign;和 sum = sum + i * sum =i sum+=arguments[i] dim i as integer dim sum as integer sum=0 for i=0 to 5 sum=s sum=sum*i/(2* i+1)和sum*=i/(2*i+1)的区别 Sum = 0 n = 0 t = 1 For i = 1 To 100 Sum = Sum + t / n n = n Sum=0 For1=1to3 Forj=i to 4 For k=j to 5 Sum=sum+1 Nex k Nex int sum=0; for( int i=1; i int i=0,sum=1; do{sum+=i++;} while(i
