Using Files

•All of the cin and cout operations work for files.

•Declaring File Streams

ifstream inFile;

ofstream outFile;

(With these data types, you cannot read from and write to the same file)

•Opening Files

inFile.open(“cone.dat”);

outFile.open(“results.dat”);

(Open associates a stream variable used in your program with a physical file on disk.)

•Specifying File Streams in Input/Output Statements

inData >> htInInches >> diamInInches >> redPrice

>> bluePrice >> greenPrice;

outData << “The painting cost for” << endl;

•
