// Cin makes use of the stream extraction operator, >>, to accept // input from the input stream buffer, placing it into a memory // location that is referenced by the identifier (variable name) // placed after the stream extraction operator. The basic format // looks like this in your code: int a; double x; char ch; string str; cin >> a; cin >> x; cin >> ch; cin >> str; // A cout is always used to prompt users of your program to enter // the appropriate data. Thus, every cin above should be preceded // by a cout, like this: cout << "Enter an integer here: " << endl; cin >> a; // More than one input can be accomplished by a cin statement. In // such a case, the user prompt should include explicit instructions // as to the type and order of the inputs. For instance, in the // following code, cout << "Enter an integer value, followed by a space," << "then a double value. Be sure to press. "; cin >> a >> x; // Without explicit instructions, your user might enter the values // with no space between. this would result in values like, perhaps, // 46 and 57.9 to become 4,657 and 0.9 as placed into a and x // respectively, instead of the intended values.
