输入输出乘法口诀！

#include<iostream>
#include<fstream>
#include<string>
using namespace std;

void Cf()
{
ofstream of("cf.txt");

for(int i=1;i<10;i++)
{
for(int j=1;j<=i;j++)
{
of << i << "*" << j << "=" << i*j << " ";
}
of << endl;
}
}


int main()
{

Cf();

ifstream infile("in.txt");
ofstream outfile("out.txt");
if(!infile)
{
cerr <<"error file";
return -1;
}
if(!outfile)
{
cerr <<"write error";
return -1;
}
string word;
while(infile >> word)
{
cout << word << endl;
outfile << word << endl;
}
return 0;
}

这个程序是很简单，我想请大家点评一下我的程序是否符合书写规范！

[racewind]

#include<iostream>
#include<fstream>
#include<string>
using namespace std;

void Cf()
{
ofstream of("cf.txt");

for(int i=1;i<10;i++)
{
for(int j=1;j<=i;j++)
{
of << i << "*" << j << "=" << i*j << " ";
}
of << endl;
}
}


int main()
{

Cf();

ifstream infile("c1.cpp");
ifstream infiles("c2.cpp");
ofstream outfile("out.txt");
if(!infile)
{
cerr <<"error file";
return -1;
}
if(!outfile)
{
cerr <<"write error";
return -1;
}

string word,words;

while(infile >> word)
{
cout << word << endl;
outfile << word << endl;
}

outfile << "........................................................................" << endl;

while(infiles >> words)
{
cout << words << endl;
outfile << words << endl;
}

return 0;
}

能不能在一个循环里实现同时写2个文件的任务那？前提是不覆盖之前写入的内容？
