Input in C++
The cin object in C++ is used to accept the input from the standard input device i.e., keyboard. it is the instance of the class istream. It is associated with the standard C input stream stdin. The extraction operator(>>) is used along with the object cin for reading inputs. The extraction operator extracts the data from the object cin which is entered using the keyboard.
Program 1:
Below is the C++ program to implement cin object to take input from the user:
C++
// C++ program to demonstrate the // cin object #include <iostream> using namespace std; // Driver Code int main() { int i; // Take input using cin cin >> i; // Print output cout << i; return 0; } |
Input:
Output:
Note: Multiple inputs can also be taken using the extraction operators(>>) with cin.
Program 2:
Below is the C++ program to implement multiple inputs from the user:
C++
// C++ program to demonstrate the taking // multiple inputs from the user #include <iostream> using namespace std; // Driver Code int main() { string name; int age; // Take multiple input using cin cin >> name >> age; // Print output cout << "Name : " << name << endl; cout << "Age : " << age << endl; return 0; } |
Input:
