True or False? With argument passage by reference, the address of the caller's argument is sent
to the function. True or False? If a function contains a statement that changes a value parameter,
only the copy of the caller's argument is changed, not the original. A function SomeFunc has
two parameters, alpha and beta, of type int. The data flow for alpha one-way, into the function.
The data flow for beta is two-way, into and out of the function. What is most appropriate
function heading for SomeFunc? void SomeFunc(int alpha, int beta) void SomeFunc(int&
alpha, int beta) void SomeFunc(int alpha, int& beta) void SomeFunc(int& alpha, int& beta)
Consider the function definition void Demo(int intVal, float& floatVal) {intVal = intVal * 2;
Solution
18) true , in call by reference the address of the actual parameter is passed to function to access
it's value in that address.
19) true , because you are modifying formal parameter in this case.
20) option C is correct
Because alpha variable uses call by value (I.e value is passed only ) and beta variable uses call
by reference (any changes made are reflected back I.e two way)
