|But if we use call by reference method in which original values are passed then a function can return more than 1 value at a time.
void areaperi(int,float *,float *);
printf("\nEnter radius of a circle");
printf("\n Area=%f \n Perimeter=%f,area,perimeter");
void areaperi(int r, float *a, float *p)

|Yup @Nitish, you are right. That's what I wanna say. A function can return multiple values by using call by reference. A mixed call containing call by value and call by reference can do it also.|

|Can anyone give the correct explanation for this?|

|It can only return 1 value. We are not directly getting two values by using call by reference, we have nowhere used return statement two times. Therefore function can only return 1 value.|

|Usually function returns only one value, but using structures we can return more than one value.|
