How can I make an " if " statement true using a number in-between 2 numbers? C++

In my opinion I feel like many people are confused about this question. What I want to do is ask the user for a number and if it is between 0 - 17, the output I would want it to be is:

Too Young

And if it is 18 - 42, the output should be:

Adult

And if it's 43 and over to be:

Senior

All while using the switch statement

Here is the code I used:

#include <iostream>
using namespace std;

int main()
{
    int age;
    cin >> age;
    if (age <= 16) {
        cout <<"Too young";
    }
    if (age <= 42) {
        cout << "Adult";
    }
    if (age <= 70) {
        cout << "Senior";
    }

    return 0;
}

The output of my code is:

Too YoungAdultSenior

Please help me out.

Replace your code with:

#include <iostream>
using namespace std;

int main()
{
    int age;
    cin >> age;
    if (age <= 17) {
        cout <<"Too young";
    } else if (age <= 42) {
        cout << "Adult";
    } else {
        cout << "Senior";
    }

    return 0;
}

The perfect way:-

#include <iostream>
using namespace std;

int main()
{
    int age;
    cin >> age;
    if (age < 18 && age >=0) {
        cout <<"Too young";
    } else if (age >= 18 && age <= 42) {
        cout << "Adult";
    } else if(age > 42)
        cout << "Senior";
    }

    return 0;
}

This is how you would do it with a switch statement btw:

#include <iostream>
using namespace std;

int main(){

    int age;
    cin >> age;

    switch (age) {
        case 0: case 1: case 2: case 3: case 4: case 5: case 6: case 7: case 8: case 9: case 10: case 11: case 12: case 13: case 14: case 15: case 16: case 17:
            cout << "Too young\n";
            break;
        case 18: case 19: case 20: case 21: case 22: case 23: case 24: case 25: case 26: case 27: case 28: case 29: case 30: case 31: case 32: case 33: case 34: case 35: case 36: case 37: case 38: case 39: case 40:
            cout << "Adult\n";
            break;
        default:
            cout << "Senior\n";

    }

    return 0;
}

In the above answer, if you wish to use using namespace std;, simply use this piece of code:

#include <iostream>
using namespace std;

int main()
{
    int age;
    cin >> age;
    if ((age>=44) && (age <= 56))
    {
       cout << "YAY!!!\n";
    }
    return 0;
}

To check if something is 2 conditions at the same time, use the && operator, which means and and checks for two conditions being true either side. Example for age between 44 and 56:

#include <iostream>

int main()
{
    int age=55;
    if ((age>=44) && (age <= 56))
    {
       std::cout << "YAY!!!\n";
    }
    return 0;
}

In C++11 - instead of &&, you can use and keyword.
