Chapter 4 warm up exercises
If input data are
10 20 30 40 50 60
10 20 30 40 50 60
10 20 30 40 50 60
70 80
and the input statements are:
cin >> a >> b >> c;
cin.ignore(100, ‘\n’);
cin.get(ch1);
cin >>d >>e >>f;
cin.ignore(100, ‘\n’);
cin.ignore(100, ‘\n’);
cin >> a >> b;
what is produced by
cout << a <<” “ <<b <<endl;
cout << c <<” “ <<d <<” “<<e<<endl;
cout <<f<<endl;
What is the effect of the following statements?
String coco;
isfstream inFile;
infile.open(“datafile.dat”);
getline(infile, coco);
Suppose a file named bobo.data contains only a collection of whole numbers.
Write the statements necessary to read all the data from the file and output the number of
items in the file.
