About switch statement

[aman rathi]

In my program i want to execute same statement on case 3 and 5 in switch() i searched lot on google about this but get nothing please help me

case 3,5:

I know it is wrong but if you have any idea about this than please help me.

[Majestics]

CASE 3:
CASE 5: fucntion();

This is the method for multiple choice in switch.

[aman rathi]

it is possible to that by writing the same statements twice under case 3 and 5 separately but that's not what i want.

[aman rathi]

thanks i got it

[aman rathi]

below is one class of my program i got one error in thid

duplicate case label at line 107
case 3:

code:

i want if user press 3 it executes both cases 1 as well as 2 please help.

[Ezzaral]

There is not a way for that to fall through both conditions on your switch. Use an if condition instead.

[Majestics]

Switch statement is made to reduce if else statment, as u have only few condition ,y dont u use if else rather then switch... Still u want to use switch the in case 3 write both code of case 1 and case 2.

[Ezzaral]

I'd also recommend re-writing the code to put the code you have in those switch cases into a function or use a variable for which array elements to operate on, because the only differece between them seems to be"fixdep_status-1" vs "fixdep_status-2".

There's no reason to repeat that much code.

[Majestics]

Yup I agree with @Ezzaral, You must create seperate functions for each of the code which are executing under cases... and call both function in case 3. :)

[aman rathi]

doing it by using if-else is better. idea of putting code in separate function is awesome. thanks to all for showing interest.

[aman rathi]

any other suggestions most welcome.
