Can you explain what 'overloading' means in the context of programming?

In programming, the term "overloading" refers to the ability to create multiple functions or methods with the same name but different parameters (types or number). This allows using one name for different operations, enhancing code readability and convenience.

For example, in C++, you can overload a function to work with different data types:

int sum(int a, int b) {
    return a + b;
}

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

Here, the sum function is overloaded for integers and floating-point numbers.
