One of the people who are uncomfortable, waste me three days

This is a small program for testing ifstream.

//testifstream.cpp

#include #include using namespace std; ifstream readfile; char buffer [300];

Void f () {readfile.read (buffer, 1000); int count = readfile.gcount (); buffer [count] = '/ 0';}

INT main () {f (); cout << buffer; cout << readfile.gcount () << endl; // outputs the number of bytes of bytes recently read cout << buffer << Endl; // read Byte System ("Pause"); return 0;}

Description: Test file Test.cpp under Debug

Finally, I found out anything in VC.

And directly double-click EXE file under Debug files.

Finally, I put ifstream readfile ("test.cpp");

Change to IFStream Readfile ("TestifStream.cpp");

That is, open itself, this is found correctly in VC, then double-click the EXE file in the debug folder to run incorrect

This is this is a bad place to find VC:

That is, in the VC environment, look up in the PROGJET directory

Double-click EXE when you look down under the debug file in the current directory of the exe file.

Why do you want to design?

Wasted me 3 days, hehe! ! !
