Function Overloading
Function overloading is a feature in programming languages that allows multiple functions to have the same name but different parameters. This enables programmers to create functions with similar functionality but different input types, making code more flexible and reusable.
Explanation of the correct answer:
The correct answer is option 'B' - Functions with the same name and different parameter types are overloaded.
Function Overloading with Different Parameter Types:
When two or more functions have the same name but different parameter types, they are considered overloaded functions. The compiler can differentiate between these functions based on the number, order, and types of parameters.
Example:
Let's consider an example to understand this concept better. Suppose we have a function named "add" that performs addition. We can overload this function to handle different data types as parameters:
```cpp
int add(int a, int b) {
return a + b;
}
float add(float a, float b) {
return a + b;
}
double add(double a, double b, double c) {
return a + b + c;
}
```
In the above example, we have three overloaded versions of the "add" function. The first version takes two integers as parameters and returns an integer. The second version takes two floats as parameters and returns a float. The third version takes three doubles as parameters and returns a double.
Benefits of Function Overloading:
- Improved code readability: Function overloading allows programmers to use the same function name for similar operations, making the code more intuitive and easier to understand.
- Code reusability: With function overloading, you can reuse the same function name for different data types or parameter combinations, reducing code duplication.
- Flexibility: Overloaded functions provide flexibility in terms of the types and number of parameters they can accept, allowing for more versatile code.
Conclusion:
Function overloading is a powerful feature in programming languages that allows multiple functions to have the same name but different parameter types. This promotes code reuse, readability, and flexibility. In the given options, option 'B' correctly identifies that function overloading occurs when functions have the same name but different parameter types.
