Answer 1

Haram Abbas ,

furst of all the code should be written well-formed, this will increase the readability.

input requires an int value. a working switch case could be like:

...
int main() {
int age;
cin>>age;
switch(age){
case 22:
cout<<"you are 22 years old";
break;
case ...
...
default:
cout<<"no special cases";
}
...

Answer 2

Run the program.

Answer 3

That's what your cin is for...

your switch is written wrong, though.
