u Calculate e
问题陈述:
杭州电子科技大学 HANGZHOU DIANZI UNIVERSITY Online Judge Problem - 1012
问题解析:
简单题,注意输出格式。引入<iomainip>头文件,调用setprecision()函数设置精度。
代码详解:
#include <iostream>
#include <iomanip>
#include <cstdio> using namespace std; int factorial(int); int main()
{
int i, n;
double e;
cout << "n" << " " << "e" << endl;
cout << "-" << " " << "-----------" << endl;
for(n=; n<=; n++) {
e = ;
for(i=; i<=n; i++) {
e += 1.0/factorial(i);
}
if(n < ) {
cout << n << " " << e << endl;
}else {
cout << fixed << setprecision() << n << " " << e << endl;
}
}
return ;
} int factorial(int n) {
if(n == ) {
return ;
}else {
return n * factorial(n-);
}
}
