# Compiler Error C2102

'&' requires l-value

The address-of operator ( `&` ) must have an l-value as operand.
The [address-of operator (**`&`**)](../../cpp/address-of-operator-amp.md) must have an l-value as operand. Address of temporary values cannot be taken.

The following sample generates C2102:

```cpp
// C2102.cpp
int func()
{
return 1;
}

int main()
{
int* ptr = &func(); // C2102
}
```
