multiple returns in a routine

[Essam Daoud]

Hi
can one have more than one retrun statement in a routine? the return statmets are nested in conditional "different scope" blocks.

thanks

yes, for example

int function(){

if(x) return(1);

if(y) return(2);

if(z) return(3);

return(0);

}

yes, for example

int function(){

if(x) return(1);

if(y) return(2);

if(z) return(3);

return(0);

}

compared to below, what is opinion on code size and speed?

it is very easy to have return()'s all over the place, which can lead to confusion - but makes for less planning and ease...

ie, some would say "one entry point and one exit point" - I grew up with this thinking but I am not so sure about it any more ;)

interesting to read peoples thoughts on this too!

int function(){

int retVal=0; //default

if(x) retVal = 1;
else
if(y) retVal = 2;
else
if(z) retVal = 3;

return(retVal);

}
