cin statement in c++ programming language

 

The cin object in C++ is an object of class iostream. It is utilized to acknowledge the contribution from the standard information gadget for example console. It is related with the standard C information stream stdin. The extraction operator(>>) is utilized alongside the item cin for understanding sources of info. The extraction administrator separates the information from the item cin which is placed utilizing the console.

Program 1:

Below is the C++ program to implement cin object:

• C++

// C++ program to demonstrate the // cin object #include <iostream> using namespace std;    // Driver Code int main() {     string s;        // Take input using cin     cin >> s;        // Print output     cout << s;        return 0; } Input:  s=10   Output: s=10 The cin can likewise be utilized with some part works which are as per the following: cin.getline(char *buffer, int N): It peruses a flood of characters of length N into the string cradle, It stops when it has perused (N - 1) characters or it tracks down the finish of the document or newline character(\n). The following is the C++ program to execute cin.getline(): // C++ program to illustrate the use // of cin.getline #include <iostream> using namespace std;    // Driver Code int main() {     char name[5];        // Reads stream of 3     // characters     cin.getline(name, 3);        // Print output     cout << name << endl;        return 0; } Program 2: Multiple inputs using the extraction operators(>>) with cin. Below is the C++ program to take multiple user inputs:   C++ // C++ program to illustrate the take // multiple input #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; }
