If you have a array

char array[32];

You can get the size like this


However, if you make a pointer to the array

char* parray = array;

and do this


you will get the size of the pointer, not the array.

If you need to send an array as a function argument, the common way to do it is
to send the size of the array as well:

void my_func(char *array, int array_size)

If you have a array of ints, int array[32], you would have to get the size like this:

sizeof(array) / sizeof(int);

This is cumbersome at best. You should probably use a C++ vector instead:

vector<int> vec;

add a integer to the vector


and get the number of elements like this


To send the vector as an argument to a function, the prefered way to do it is

With write access:
void my_func(vector<int>& vec)

Without write access:
void my_func(const vector<int>& vec)
