Thread: C++ file access

I have a text file, either created manually, or as an output from a vb program (not yet completed, so output format can be modified slightly), that I need to input into my c++ program. I need to be able to read a series of integers, characters and floats from the file, in order and assign these values to the correct type of variable.
Currently, I can only open the file and read in the character values bit by bit or in blocks. Does anyone know how I can get this to work?

ifstream will open a file for reading, as tho it were coming from cin

ifstream input("filename.txt");
int anInt;
char aChar;
double aDouble;
float aFloat;

if ( input.fail() )
{
cout << "Error unable to open filename.txt";
return -1;
}
input >> anInt >> aChar >> aDouble >> aFloat;

That would read an int, a char, a double, then a float from the file "filename.txt"
