How to calculate adult age in C / C++ language using if-else and switch statment?

Calculating adult age in c languages 

Here we  writing code of c language 

// How to Know that the person is adult and child in c language ?
1.
#include <stdio.h>
#include <conio.h>
int main()
{
    // Here we declared the variable
    int age;
    printf("Enter age of the person :");
    scanf("%d", &age); //Here we entered the age
    // We use if else statement for check that entered age person was child or adult

    {
        printf("This age person is Adult");
    }
    else
    {

        printf("This age person is Child");
    }
    return 0;
}

Output -
Enter the age of the person :12
This age person is Child


2. 
using switch statement 
// making age checker through switch statement

#include <stdio.h>
int main()
{
    int option;
    printf("Enter the option in the following :\n");
    printf("1.Age is greater then 18\n");
    printf("2.Age is lesser then 18\n\n");
    // printf("3.Age is greater then 18\n")

    printf("Entered the option :\n");
    scanf("%d", &option);
    switch (option)
    {
    case 1:
        printf("\nThe person is Adult\n ");
        break;
    case 2:
        printf("\nThe person is Child \n");
        break;

    default:
        printf("Entered option is invalid \n");
        break;
    }
}

Output -
Choose the option in the following :
1.Age is greater then 18
2.Age is lesser then 18

Entered the option :
1

The person is Adult

Making this code in c++ language -

// How to Know that the person is adult and child in c language ?
1 . check the age of the person and result that the person is child or not 
#include <iostream>
using namespace std;
// #include <conio.h>
int main()
{
    // Here we declared the variable
    int age;
    cout << "Enter age of the person :";
    cin >> age; //Here we entered the age
    // We use if else statement for check that entered age person was child or adult
    if (age > 18)
    {
        cout << "This age person is Adult";
    }
    else
    {

        cout << "This age person is Child";
    }
    return 0;
}


output -
Enter the age of the person :12
This age person is Child

2. using switch statement in c++ code -
// Switch statement
#include <iostream>
using namespace std;
int main()
{
    int option;

    cout << "This are the option you have choose : " << endl;
    cout << "1. Age is greater then 18" << endl;
    cout << "2. Age is lesser then 18" << endl;

    cout << "Enter the option :" << endl;
    cin >> option;

    switch (option)
    {
    case 1:
        cout << "The person is Adult" << endl;

        break;
    case 2:
        cout << "The person is child" << endl;

        break;

    default:
        cout << "ENTER VALUE IS INVALID SO REFRESH";
    }
}

output -
choose the option in the following :
1.Age is greater then 18
2.Age is lesser then 18

Entered the option :
1

The person is Adult

Class and Object , function overloading Explanation in c++ language

 Classes in C language - It is a user defined data type data type which hold its own data members and member function which can be accessed and user by creating an instance of that class and we say that class is building block that leads to Object Oriented programming  Data member -  It is the data variable of the function  Member function - It are the function use to manipulate these function variable  For Example -  A car is an object the car has attribute such as weight , color and methods such as drive and brake Attribute and method are basically variable and function that belong to class syntax - class   class{        // The class    public :              // Access specifier      int   Num;         // Attribute (int variable)     string word;   // Attribute (string variable) }; Program - // class explaination #include <iostream> using   namespace  std; class   classname {      public:      string   mystring ;      void   printfun ()     {          cout   <<   "Gee

C++ programming tutorial 5

 Call by value or reference - There are two type in function call by value or call by reference in it we pass the value in call by value we pass value and in call by reference we pass the reference of the value . Call by value in C++ Programming language  :- In call by value we pass the variable or say argument and then it used by function which we made so see the code given below  Syntax - #include <iostream > using namespace std; // making function  void fun_name(int a, int b) { ... } int main() { //calling function  fun_name(int n,int n1); return 0; } Code -  // function call by value in C++ programming #include <iostream> using namespace std; // call by value in function declaration void container(int a, int b); int main() {   int x,y;   cout<<"Enter the value of x :"<<endl;   cin>>x;   cout<<"Enter the value of y :"<<endl;   cin>>y;   // here we passing the value as argument   // and also calling the function
