Question

n!=1*2*3*...*n, 试写出计算1!+2!+3!+...+100!的程序语句

用循环语句
basic

Answer 1

//求阶乘的值
Function getFactorial(num as Integer) as Integer
if num=0 or num =1 then getFactorial=1
elseif num>1 then
getFactorial=num*getFactorial(num-1)
end if
End Function

//num 为最大的那个数，如1!+2!+...+8!,则num为8
Function getSum(num as Integer)as Integer
Dim sum
sum=0
for i=1 to num
sum=sum+getFactorial(i)
next i
End function

我只写了函数，剩下的自己应该怎么做了。
