in the array. True False c++ allows you to partially initialize an array. True False If data are sorted in ascending order, it means they are ordered from to True False The * operator is used to get the address of variable. True False Any mathematical operation, including multiplication and division, may True False A structure declaration does not define a variable. True False A function may return a structure. True False fstream objects are only capable of performing file output operat True False Write a complete C++program which will add two integers and print the result using call by reference method. This ADD function will then be called by the calledExplanation / Answer
Ans : The call by reference method of passing arguments to a function copies the ... in the following function swap(), which exchanges the values of the two integer int &y) {int temp; temp = x; /* save the value at address x */ x = y; /* put y into ... #include <iostream> using namespace std; // function declaration void swap(int &x, int &y).
The call by reference method of passing arguments to a function copies the reference of an argument into the formal parameter. Inside the function, the reference is used to access the actual argument used in the call. This means that changes made to the parameter affect the passed argument.
To pass the value by reference, argument reference is passed to the functions just like any other value. So accordingly you need to declare the function parameters as reference types as in the following function swap(), which exchanges the values of the two integer variables pointed to by its arguments.
/ function definition to swap the values.
let us call the function swap() by passing values by reference as in the following example:
When the above code is put together in a file, compiled and executed, it produces the following result:
