I.10: Can an array be an lvalue?

Answer:
In I.9, an lvalue was defined as an expression to which a value can be assigned. Is an array an expression to which we can assign a value? The answer to this question is no, because an array is composed of several separate array elements that cannot be treated as a whole for assignment purposes. The following statement is therefore illegal:

int x[5], y[5];
x = y;
You could, however, use a for loop to iterate through each element of the array and assign values individually, such as in this example:

int i;
int x[5];
int y[5];
...
for (i=0; i<5; your_name =" my_name;">Reference:
