T F A function may return a structure.
Short Answer
Expert verified
Provide a brief reasoning and an example.
Answer: True, a function may return a structure.
Reasoning: In many programming languages, a structure (or struct) is a composite data type that groups variables under a single identifier. Functions can return data of any type, including structures. When a function returns a structure, it is returning an instance of that structure with its variables' values.
Example (in C programming language):
```c
#include
// Declare the structure
struct Point {
int x, y;
};
// Function that returns a Point structure
struct Point createPoint(int x, int y) {
struct Point pt;
pt.x = x;
pt.y = y;
return pt;
}
int main() {
struct Point p1 = createPoint(1, 2);
printf("Point coordinates: (%d, %d)\n", p1.x, p1.y);
return 0;
}
```
In this example, we define a structure `Point` with two integer variables `x` and `y`. The function `createPoint` takes two integers as input and returns a `Point` structure with the values of `x` and `y`. In the main function, we call `createPoint` and assign the returned structure to `p1`, and then print the coordinates of the point.
