C++ Input Statement
Overview
In this tutorial, we will learn the C++ input statement with the help of a sample program. The basic input object to take input from the standard input device is the cin object.
C++ Input Statement
We use the cin input object and the >> operator to take the input from the standard device. The C++ standard input device is the keyboard.
For example, to take input to an integer variable called num, we can use the following statement
cin >> num;
C++ Program
We will write a simple C++ program to understand the concept. We will write a simple program to read an integer value from the standard input device i.e keyboard, store the value in a variable and display the value to the computer screen.
/************************************ * C++ Input * Filename: input.cpp * Program to take user input from standard * input device. * C++ Tutorials - www.TestingDocs.com **************************************/ #include using namespace std; int main() { int num; //declare integer variable cout << "Enter integer input:"; // User prompt cin >> num; // C++ Input Statement cout << "The value is =:" << num << endl; return 0; } // end main
Sample Output
Enter integer input:79
The value is =:79
