输入值增量的总和数组

Question

我正在尝试编写一个接受两个输入值的求和数组函数。第一个输入值递增添加，直到达到第二个输入的值。例如，如果 lowerLimit 为“2”，upperLimit 为“5”，总和将为 2 + (2+1) + (2+2) + (2+3) + (2+4) + (2+ 5) = 27。我尝试使用添加到 lowerLimit 的变量“i”并逐渐上升直到 (i

Answer 1

数组有什么用？ 您可以直接添加它们并给出输出而不使用数组...

试试这个代码：

var sum=lowerLimit; for(i=1; i<=upperLimit; i++){ sum += (lowerLimit+i); }

Answer 2

抱歉，该代码有错误

var sum=lowerlimit;
for(i=1; i<=upperLimit; i++){
  sum += (lowerLimit+i);
}
