Using cin >>

Using cin >>

We have seen how the double arrows (<<) of the cout show that the information is going "out" to the monitor.  In a similar way, the double arrows (>>) of the cin (pronounced see-in) show characters flowing "into" the program.  The arrows point the way. When using cin, it is always necessary to provide a variable to the right of the operator to receive the input. Sample program: // sample program for cin #include <iostream.h> int main(void) {      int fleas;      cout << "How many fleas does your cat have?";      cin >> fleas;      cout << "Well, that's " << fleas << " fleas too many!! \n\n\n";      return 0; }   cin can accept more than one variable as follows: cout << "Enter an integer and a decimal:"; cin >> integer >> decimal; You would enter the values by typing on a single line and leaving a space between them, or by typing them on separate lines and hitting ENTER after each entry.
