Cin is a blocked input So cin >> a returns cin, which can be used as (cin>>a)>>b and so forth. Whatever comes from the keyboard is stored in a buffer
When you press enter the system passes the buffer to the application code (std::cin code) Each call to operator>>(istream&, t) (where t is some arbitrary type) returns a reference to its first argument Depends on the type of the operand.
3 there is no close equivalent to cin in c However, you can read things in c using the c standard library, you can look at the relevant part here (cstdio reference). Using cin's >> operator will drop leading whitespace and stop input at the first trailing whitespace To grab an entire line of input, including spaces, try cin.getline().
79 cin is an object of class istream that represents the standard input stream It corresponds to the cstdio stream stdin The operator >> overload for streams return a reference to the same stream The stream itself can be evaluated in a boolean condition to true or false through a conversion operator
When you use the >> operator, cin reads up until the next whitespace character, but it doesn't process the whitespace So when you have std::cin >> str1 The second call will just process the newline character, and you won't have a chance to type in any input Instead, if you're planning to use getline after an operator >>, you can call std::cin.ignore() to eat.
How do i use cin for an array asked 7 years, 1 month ago modified 1 year, 7 months ago viewed 78k times I understand that cin.eof() tests the stream format And while giving input, end of character is not reached when there is wrong in the input I tested this on my msv c++ 2010 and am not understand.
Yes, you can input multiple items from cin, using exactly the syntax you describe The result is essentially identical to This is due to a technique called operator chaining
