WebPassing array to function using call by reference When we pass the address of an array while calling a function then this is called function call by reference. When we pass an address as an argument, the function declaration should have a pointer as a parameter to receive the passed address. WebPassing arrays to functions in C/C++ behaves differently because no parameter can receive an entire array. The compiler converts an array declaration into an array pointer. Why do you need to send the size of an array to a function? Usually, the name of the array “decays” to a pointer to its first element.
