Can we use operators in switch statement??

Question

eg; switch(any)
{
case 9&&10&&11:
cout<<" some thing" ;
break;
}

Answer 1

Yes.. U can use
but the case should not repeat...
Like we know by using logical operators only 0 & 1 value can be obtained so u can create max two cases..
for eg:-
int a=1;
switch (a){
case 1&&1:
cout<<"yes";
break;
case 1&&0:
cout<<"no";
break;
}
will output :- yes..
but if u use cases giving same answer it will generate error...
for eg:-
int a=1;
switch (a){
case 1&&1:
cout<<"yes";
break;
case 1||0:
cout<<"no";
break;
}
this will generate error as both cases have value 1

Answer 2

@mubarak
int a;
cin>>a;

Answer 3

@Mubarak if the case value repeats it will give execution error.... "duplicate error"...😊
@Anderson U cannot use x, y variable... only constants are used...
but u can use it by making x & y constants....
like this...:- 👇

int main() {
int a=1;
int const x=2;
int const y=3;
switch (a){
case (x<y):
cout<<"yes";
break;
case (x>y):
cout<<"no";
break;
}
return 0;
}
// outputs:- yes

Answer 4

@DT is there any way to write case (x <= y): statements?

Because it was actually a compiling error if it was written as shown...

The reason I wanted to do this it's because it would look messy to have a bunch of 'if' statements...

Answer 5

if it repeats, it will give the same value or execution error??

Answer 6

@DT but i want a value from user,
