Embedded System Question:
Explain Why cannot arrays be passed by values to functions?
Answer:
Because in C when you say the name of the array it means the address of the first element.
example :
int a[];
func (a);
int func(int a[]);
In this when you call the function by passing the argument a actually &a[0](address of first element) gets passed. Hence it is impossible to pass by value in C.

int a[];
