Declaring and Defining the function

A set of statements, which performs a particular task is called a function. The program gains modularity by using function. The application is quite easy to understand, read, and edit when they are created with functions. The developer/programmer creates a function and uses main() to call the function. Once the function gets executed, the control is transferred to the main program.

### Understanding Function Overloading in C++

**Objective:** Determine the output of the following program.

```cpp
#include <iostream>
using namespace std;

void cdabs(int);
void cdabs(float);
void cdabs(double);

int main() {
cdabs(3);
cin.ignore();
return 0;
}

void cdabs(int x) {
cout << x << " is an int" << endl;
}

void cdabs(float x) {
cout << x << " is a float" << endl;
}

void cdabs(double x) {
cout << x << " is a double" << endl;
}
```

**Explanation:**

This C++ program demonstrates function overloading—a feature that allows multiple functions with the same name but with different parameter types.

- **Function Declarations:**
- `void cdabs(int);` - Declares a function that takes an integer parameter.
- `void cdabs(float);` - Declares a function that takes a float parameter.
- `void cdabs(double);` - Declares a function that takes a double parameter.

- **Main Function:**
- Calls the `cdabs` function with the integer argument `3`.

- **Function Definitions:**
- `cdabs(int x)` is called because the argument `3` is an integer. This function outputs: `3 is an int`.

- **Output:**
- The program output will be:
```
3 is an int
```

This illustrates how C++ selects the appropriate function to execute based on the parameter type during a function call. In this case, `cdabs(int x)` is chosen due to the integer argument.
