How do I call a function using an array as parameter in C++?

Answer 1

The 3rd one of Dennis answer is the common way..
template <typename T, size_t arrLength>
<returnType> func(arrayParam){//body
}
<T> myData[] = {/*...data*/};
func(myData);
but it is C style.

In C++ I will use std::vector or std::array , they are objects and provide all the necessary methods to work whit inside your body.

template <typename T>
void print(std::vector<T> data){
for( typename std::vector<T>::iterator it = data.begin() ; it != data.end() ; ++it )
std::cout<< *it ;
}

DarkRanger It's a lot of things to learn quickly!
You may start with STL data structures because they are the bricks of DSA, pick one and learn it very well, the others will be easy later because the style and design is the same.
Start with vector I say.

If you want to develop your own DSA it's another story..
you have to learn manual memory management.
Anyway a knowledge of STL design is good to build your own library in a standard fashion.

And remember.. c++ and programming is not something you will learn quickly, never trust people saying they have learned it quickly.
If quickly lead you to jump of do too big steps then you will live holes in your knowledge.. they will become dooms later when you think you are formed!

void f( int* arr, size_t size ){ ... } // int arr[100]{}; f( arr, 100 );

void f( int arr[], size_t size ){ ... } // int arr[100]{}; f( arr, 100 );

template<typename T, size_t size>
void f( T (&arr)[size] ){ ... } // int arr[100]{}; f( arr );

Pick whichever you like. :)
