get and set in c++ code example

Example 1: set and get in c++

/*Get or Set are methods to Access Private Members 
for example */

class Employee {
  private:
    // Private attribute
    int salary;

  public:
    // Setter
    void setSalary(int s) {
      salary = s;
    }
    // Getter
    int getSalary() {
      return salary;
    }
};

int main() {
  Employee myObj;
  myObj.setSalary(50000);
  cout << myObj.getSalary();
  return 0;
}

Example 2: set in cpp

#include<iostream>
#include<set>
 
using namespace std;
 
int main(){
 
    // Set with values
    set<int, greater<int>> s1 = {6, 10, 5, 1};
    // s1 = {10, 6, 5, 1}
 
    // Inserting elements in the set
    s1.insert(12);
    s1.insert(20);
    s1.insert(3);
 
    // Iterator for the set
    set<int> :: iterator it;
 
    // Print the elements of the set
    for(it=s1.begin(); it != s1.end();it++)
        cout<<*it<<" ";
    cout<<endl;
 
}

Example 3: set in cpp

#include<iostream>
#include<set>
 
using namespace std;
 
int main(){
 
    // Set with values
    set<int, greater<int>> s1 = {6, 10, 5, 1};
     
    // Iterator for the set
    set<int> :: iterator it;
 
    // Print the elements of the set
    for(it=s1.begin(); it != s1.end();it++)
        cout<<*it<<" ";
    cout<<endl;
}
