    def __add__(self, other):
        return 1

    @overload(None, str)
    def __add__(self, other):
        return 2
      
@overlaod(str,[int,float])
def bar(name,age):
	return 3
  
@overload(str,str)
def bar(name,color):
	return 4
  
if __name__ == '__main__':
    print(Foo()+5) #-> 1
    print(Foo()+"s") #-> 2
	print(bar("jake",5)) #-> 3
    print(bar("jake",5.5)) #-> 3
    print(bar("jake","blue")) #-> 4

function

A function is a set of statements that take inputs, do some specific 
computation and produces output.

The idea is to put some commonly or repeatedly done task together and make a 
function so that instead of writing the same code again and again for different
inputs, we can call the function.

function

function nama_function(parameter/argument 1, parameter/argument 2, ...) {
  [Isi dari function berupa tindakan/steatment]
  return [expression];
}

function

// function declaration
void greet() {
    cout << "is it possible";
}

function

// function bilal(){
//     console.log("bilal joyia")
// }

// bilal();

// function future(){
//     console.log("developer")
// }
// future();

create a function

function foo {
# code here
}

function

<type> function(parameter)
{
	do this;
    return value;
}

/*
int add(number1, number2)
{
	return number1 + number2;  
}
print(add(2,3));
*/

function

int main()
{
   foo();
   getchar();
   return 0;
}
void foo()
{
   printf("foo called");
}
