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

        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;

    }

}

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;

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
