Question

The parameter passing mechanism used in c is_____ ​

Answer 1

The parameter passing mechanism used in C is call by value and call by reference.

• There are two parameter passing methods, call by value and call by reference.

• The value passed by the actual parameter is a value call. The call by value method allows the procedure to modify the parameter's value.

• Whereas the call by reference method guarantees that the parameter's value will be unchanged by the procedure.

• Call by reference is the passing of the address of the memory location where the actual parameter is typically stored.
