Function overloading allows you to define multiple functions with the same name but different parameter lists. This enables you to create functions that perform similar tasks on different types of data.

// Function overloading
int add(int a, int b);
double add(double a, double b);

// Function definitions
int add(int a, int b) {
return a + b;
}

double add(double a, double b) {
return a + b;
}

• In the above example, the add function is overloaded to work with both integer and floating-point numbers.

Functions play a crucial role in modularizing code and making it more maintainable. By mastering the concepts of declaring, defining, passing arguments, returning values, and overloading functions, you’ll gain the skills needed to write structured and efficient C++ programs.
