Web probably the easiest way to read a whole text file is just to concatenate those retrieved lines. Web what is the best way to slurp a file into a std::string in c++? This requires the std::string 's data to be contiguous which is not required by the standard, but it appears to be the case for all known implementations. If ( myfile.is_open() ) { while ( myfile.good() ) { myfile >> mystring; Determine size of file in characters. } } once we reach the end of the file, myfile.good() evaluates to. Use std::vector and declare a vector of that size, or use the new operator and dynamically allocate a char array. I try to read the entire text file using vc++ with this code. Stream class to read from files fstream: Web initial values of (*dataptr) and (*sizeptr) are ignored.
If ( myfile.is_open() ) { while ( myfile.good() ) { myfile >> mystring; Use std::vector and declare a vector of that size, or use the new operator and dynamically allocate a char array. 27 a few things i would do differently: I try to read the entire text file using vc++ with this code. Ifstream::pos_type pos = ifs.tellg (); Char *contents = new char [size]; /* a read error already occurred? Use ifstream::read to read in the entire file. Web viewed 6k times. While (std::getline(file, str)) { file_contents += str; Web initial values of (*dataptr) and (*sizeptr) are ignored.
