To answer this question, we need to understand method overloading in C#. Method overloading allows us to define multiple methods with the same name but with different parameters. This enables us to perform different operations based on the arguments passed to the method.
Let's go through each option to understand why it is correct or incorrect:
Option A) Different parameter data types - This option is correct. Method overloading can be achieved by having methods with the same name but with different parameter data types. For example:
void Print(int num)
{
// Do something with an integer parameter
}
void Print(string text)
{
// Do something with a string parameter
}
Option B) Different number of parameters - This option is correct. Method overloading can also be achieved by having methods with the same name but with a different number of parameters. For example:
void Sum(int num1, int num2)
{
// Do something with two integer parameters
}
void Sum(int num1, int num2, int num3)
{
// Do something with three integer parameters
}
Option C) Different order of parameters - This option is correct. Method overloading can be achieved by having methods with the same name but with a different order of parameters. For example:
void Calculate(int num1, int num2)
{
// Do something with two integer parameters in a specific order
}
void Calculate(int num2, int num1)
{
// Do something with the same integer parameters in a different order
}
Option D) All of these - This option is correct. All of the mentioned options are valid ways to overload a method in C#. By combining different parameter data types, different numbers of parameters, and different orders of parameters, we can achieve method overloading.
The correct answer is D) All of these. This option is correct because all the mentioned ways are valid ways to overload a method in C#.
