编程求1+1+2+1+2+3+.....+1+2+3+....+100的值

vb循环语法忘了，这是Java的 你自己改改

public class Demo {

public static void main(String arg[]){
int i = 1, sum = 0;
while(i <= 100){
sum += (1 + i) * i / 2;
i++;
}

System.out.println("结果：" + sum);
}

}

dim result,sum(100)
for i=1 to 100
for j=1 to i
sum(i)=sum(i)+j
next
result=result+sum(i)
next
