可以计算大（8位）阶乘的c ++程序 [英] c++ program that can calculate big (8-digit) factorials

问题描述

嗨

i必须编写一个c ++程序，可以使用17的矢量（例如c）计算大因子，c [i]可以容纳8位

i需要帮助

当然，你到目前为止有什么？

当然，你有什么至今？

i已经做了但是我的代码不正确

i不知道如何收集我所拥有的所有信息。我写的是像这样：

int a; //我们想要计算其阶乘的数字

int n = a; int b = a;

for（int i = 16; i> = 0; i = i + 1）

{c [i] = n;

而（c [i]< p）// p是e + 9

{b = b-1;

c [i] =（c [i] *（b％10））+（c [i] *（b / 10）* 10） ;

}

}

但我知道错了

你能帮我开始一个新代码吗？

Sure, what do you have so far?

Sure, what do you have so far?

i have done sth abt it but my code is incorrect
i do not know how to gather all the informations that i have.i wrote sthe like this:
int a ; //the number which we want to calculate its factorial
int n=a;int b=a;
for(int i=16;i>=0;i=i+1)
{ c[i]=n;
while(c[i]<p) //p is e+9
{ b=b-1;
c[i]=(c[i]*(b%10))+(c[i]*(b/10)*10);
}
}
but i know its wrong
could you plz help me starting a new code?
