将文件读取到C ++中的字符串 [英] Reading a file to a string in C++
本文介绍了将文件读取到C ++中的字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
f = open('transit_test.py')
s = f.read()
什么是最短的C ++习惯做这样的事情?
解决方案
>
#include< string>
#include< iterator>
#include< fstream>
使用namespace std;
wifstream f(Ltransit_test.py);
wstring s(istreambuf_iterator< wchar_t>(f),(istreambuf_iterator< wchar_t>()));
As somebody who is new to C++ and coming from a python background, I am trying to translate the code below to C++
f = open('transit_test.py')
s = f.read()
What is the shortest C++ idiom to do something like this?
解决方案
The C++ STL way to do this is this:
#include <string>
#include <iterator>
#include <fstream>
using namespace std;
wifstream f(L"transit_test.py");
wstring s(istreambuf_iterator<wchar_t>(f), (istreambuf_iterator<wchar_t>()) );
