return(c); } Output: Explanation: This is an example of call by reference. Sometimes in our program a situation occurs when we are not able to pass the value of variable through function. We have to pass the address of these variables to access them. It is called call by reference. ...
Example using Call by ReferenceIn call by reference, to pass a variable n as a reference parameter, the programmer must pass a pointer to n instead of n itself. The formal parameter will be a pointer to the value of interest. The calling function will need to use & to compute the ...
Another situation in which call by reference is useful is when we need to return two or more values from a function, e. g., a function to return both area and perimeter of a circle. The call by reference mechanism is also very useful when passing large structures to a function and may...
In this program, classDemocontains three member functions, each function is returning*this, which contains the reference of the object. If the function returns a reference of an object, then we can easily call the member function using reference of object the object. ...
With call-by-reference parameter binding, the example produces different results. The first call is straightforward. The second call redefines bothaandb; those changes would be visible in the caller. The third call causesxandyto refer to the same location, and thus, the same value. Thisaliascha...

For a call-by-reference parameter, the precall sequence evaluates the parameter to an address and stores the address in a location designated for that parameter. If a call-by-reference parameter has no storage location, then the compiler may need to allocate space to hold the parameter's ...
When you call a Fortran subroutine, like a function from LAPACK or BLAS, from a C/C++ program, be sure to pass the arguments by reference. To pass by reference, precede the argument with an ampersand (&), unless that argument is already a reference. For example, when you create a matr...
