Cannot understand return value of sizeof()

Question

I have this in my code:

int x = 4;
char* array = malloc(x*sizeof(char));
size_t arraysize = sizeof (array);
printf(\"arraysize: %zu\\n\", arraysize);
         


        

Answer 1

You are calculating the size of the full array (4*sizeof(char)) But you spect to know the number of items on the array (4).

You can do

size_t arraysize = sizeof (array)/sizeof(char);

It will return 8/2 = 4
