Question

vf编程求S=10!+12!+14!

用VF编程计算求。。。。。
几位的回答算出来的答案都不对啊。。。我用计算机算了答案应该是87660921600
但是几位的答案都差好远。。。

Answer 1

int function(int fst, int sec, int trd) {
int i, sum = 0;
int subsum = 1;
for(i=1; i<=fst; i++){
subsum = subsum * fst;
}

sum = sum + subsum;
subsum = 1;
for(i=1; i<=sec; i++){
subsum = subsum * sec;
}
sum = sum + subsum;
subsum = 1;
for(i=1; i<=trd; i++){
subsum = subsum * trd;
}
sum = sum + subsum;
return sum;
}

// 函数做完了，想求答案只需要呼叫一下： int result = function(10, 12, 14) 假单吧？ 嗯嗯 ^^.

Answer 2

clear
s=0
for i=10 to 14
p=1
for j=1 to i
p=p*j
endfor
s=s+p
endfor
?s
cancel

Answer 3

clear
s=0
store 1 to m,n,k
for i=1 to 10
k=k*i
endfor
for i=1 to 12
m=m*i
endfor
for i=1 to 14
n=n*i
endfor
?"S=10!+12!+14!=",s

Answer 4

下面的回答是C程序啊！
VF应该这样编
clear
s=0
a=1
b=1
c=1
for i=1 to 10
a=a*i
endfor
for i=1 to 12
b=b*i
endfor
for c=1 to 14
c=c*i
endfor
s=a+b+c
?s
