fstream到const char * [英] fstream to const char *

问题描述

我想要做的是读取一个名为"test.txt"的文件，然后将文件的内容设置为const char *类型.怎么会这样?

What I want to do is read a file called "test.txt", and then have the contents of the file be a type const char *. How would one do this?

推荐答案

#include <string>
#include <fstream>

int main()
{
   std::string line,text;
   std::ifstream in("test.txt");
   while(std::getline(in, line))
   {
       text += line + "\n";
   }
   const char* data = text.c_str();
}

注意不要对数据进行显式调用

Be careful not to explicitly call delete on data
