Array in C
1 Answer(s)      3 years and 2 months ago
Posted in : IoC


Respected Sir,

How can an array be an lvalue, if we can't assign to it?

How can I set an array's size at run time? How can I avoid fixed-sized arrays?

help me sir!

An lvalue was defined as an expression to which a value can be assigned.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;

Additionally, you might want to copy the whole array all at once. You can do so using a library function such as the memcpy() function, which is shown here:

memcpy(x, y, sizeof(y));
