How to make ~case age>20:statement~ can be activated

Question

Here is the code http://www.sololearn.com/app/cplusplus/playground/cMVEOlcOVwle/

Answer 1

Maybe I write wrong thing

Answer 2

#include<iostream>
using namespace std;

int main(){
string age = "age \> 20";//outputs litteraly
cout << age;
}

or replace by:

int age = 21;
cout << (age>20) << endl;

and you'll get 1 which is same as a "true"...

Answer 3

int age;
cin >> age;

if(age>20){
cout<<"You aren't old..."<<endl;
}

you don't need return 0... compiler knows...

Answer 4

in your case of a switch statement, you just need to put age>20 in parentheses in order to work...

Answer 5

Thanks! return 0 is just come with program it's really annoying >:), anyway.sooo switch isnt suppose right?

Answer 6

in switch, cases must be a constants, expressions with a fixed value... age>20 is not a constant...

Answer 7

Thx very much :)
