Chapter 11: Problem 47

True or False A function may return a structure.

Short Answer

Expert verified
Answer: True

Step by step solution

01

Understanding Functions

In programming, a function is a block of code that performs a specific task. Functions may or may not take parameters, and they can return a value or not return any value. The main purpose of functions is to achieve code reusability and modularity.
02

Understanding Structures

A structure is a data type in programming languages like C and C++, which allows grouping together variables of different data types under a single name. It is similar to a record in other programming languages or a simple class in object-oriented languages that bundle related data together.
03

Functions Returning Structures

Since a structure can be considered a custom data type, a function can return a structure just like it can return any other data type (e.g., int, char, float, etc.). To achieve this, we need to define the structure, use the structure as the return type for a function, and make sure the function returns a variable of the structure type.
04

Example Function with a Structure Return Type

Suppose we have defined the following structure for a two-dimensional point: ``` struct Point { int x; int y; }; ``` We can define a function that takes two integers as input and returns a Point object: ``` struct Point makePoint(int a, int b) { struct Point temp; temp.x = a; temp.y = b; return temp; } ``` This function creates a temporary Point object, assigns values to the x and y coordinates, and then returns the object. So, a function can indeed return a structure.
05

Conclusion

Based on the example and the understanding of functions and structures, we can conclude that the statement "A function may return a structure" is: True.

What is the difference between a union and a structure?

True or False A structure member variable may be passed to a function as an argument.

include using namespace std; union Compound { int x… # Each of the following declarations, programs, and program segments has errors. Locate as many as you can. #include using namespace std; union Compound { int x; float y; }; int main() { Compound u; u.x = 1000; cout << u.y << endl; return 0; }
