Multiple values can be returned by using pointers in c...

Code
span style="color: #ff0000;">"


Enter the radius of a circle: ");


scanf("%d""


Area= %f""


Perimeter= %f"

Strictly speaking, a C function can only *return* a single value; you cant write something like "a,b,c=f();".

However, you can write to multiple function parameters in addition to returning a value (such as the library function scanf() - see code sample).

You can return values of struct type, which have multiple attributes. However, struct types should only be used represent things which *logically* have multiple fields or attributes, such as a street address (number, street name, city, state/province/whatever, postal code, etc.) or a line item in an invoice (part #, quantity, unit price, total price, etc.). You should never create a struct just to package up multiple items that have no logical relationship to each other.

Code
/**


 * Code sample 1: In addition to writing to its parameters, scanf 


 * returns the number of successful conversions


 */"%d %f %s", &x, &y, z) ==3)


{


  // process x, y, and z


}

Multiple values can be returned from a function by using call by address i.e. pointers intelligently.
