Shouldn't that switch supposed to take the age input from a user and compare it before the output? Pls, how can this be done?

Question

from the example given on switch control structure.

Answer 1

Talking about this..??

int age = 42;. /*Age is declared along with value*/
switch (age) {
case 16:
cout << "Too young";
break;
case 42:
cout << "Adult";
break;
case 70:
cout << "Senior";
break;
}

For user to give input and switch it.. you can modify it as..

int age;. //only variable declared..
cin>>age;. //value taken from user
switch (age) {
case 16:
cout << "Too young";
break;
case 42:
cout << "Adult";
break;
case 70:
cout << "Senior";
break;
}

Answer 2

#include<iostream>
using namespace std;

/*For accepting user input, You just have to define the variable later through user input.
It can be done as follows*/

int main()
{
int age;

/*Here our variable is "age".This is where you can opt for user input or preset it, i.e the variable "age" has no preset value(such as int age=42; or whatever etc), hence we have to give it a value thus we ask for user input*/

cout<<"Enter the age"<<endl;
//This is command ask for the user to input the value, note: <<endl;

cin>>age;
/*This command accepts the input , which is then forwarded to switch statement for the next part of the program to execute*/

switch(age){
case 16:
cout<<"Teen";
break;
case 42:
cout<<"Adult";
break;
case 70:
cout<<"Senior";
break;

}
}
