【笔记】C++风格的文本读入与输出

#include <fstream>
#include <iostream>
using namespace std;
bool outText(char* path, char* line)
{
ofstream f;
f.open(path,ios::out|ios::app);
if(f.is_open())
{
f<<line<<std::endl;
f.close();
return true;
}
return false;
}

int main()
{
outText("out.txt",Form("%10s %10s %10s",">0.5 MeV",">0.7 MeV",">1.0 MeV"));
outText("out.txt",Form("%10d %10d %10d",5,7,0));

return 0;
}
