In the below program, we are creating a C++ program to create a class with setter and getter methods.

在下面的程序中，我们正在创建一个C ++程序，以使用setter和getter方法创建一个类 。

#include 
    
     using namespace std;// class definitionclass Pofloat {
     private: // private data members    float x, y;  public: // public member functions    void set_xy(float x, float y);  float get_x();  float get_y();};// member functions definitionsvoid Pofloat::set_xy(float x, float y) {
     this -> x = x;  this -> y = y;}float Pofloat::get_x() {
     return x;}float Pofloat::get_y() {
     return y;}// main functionint main() {
     // creating objects  Pofloat objP;  //setting the values  objP.set_xy(36.0f, 24.0f);  //getting the values  cout << "objP is " << objP.get_x();  cout << ", " << objP.get_y() << endl;  //setting the values again  objP.set_xy(1.2f, 3.4f);  //getting the values again  cout << "objP is " << objP.get_x();  cout << ", " << objP.get_y() << endl;  return 0;}
    

Output

输出量

objP is 36, 24objP is 1.2, 3.4

See the program – here method set_xy() which is a setter method that is using to set the value of x and y and get_x(), get_y() are the getter methods that are using to get the value of x and y.

请参见程序–这里的set_xy()方法是一个setter方法，用于设置x和y的值，以及get_x() ， get_y()是用于获取x和y值的getter方法。
