Hi i have been tryin to read a gmsh text file which indicates integers, floats and some strings. the code has been posted below. i have also tried compiling and running some codes from tutorials and other sites but they share the same problem with my code. and the problem is that the .txt file opens fine but i keep getting reading error no matter what i do.
this results in myfile.fail() to return a true value for the first iteration. i added the seekg() just to make sure i will read from the beginning but the code doesnt work without it. any how the text file that i want to read is simply
and i have no idea what could be wrong with my code
any help would be greatly appreciated
