Does this mentioning array name gives the base address in all the contexts?
Question: Does this mentioning array name gives the base address in all the contexts?
[A].Yes [B].
No Answer: Option B
Explanation:
No, Mentioning the array name in C or C++ gives the base address in all contexts except one.
Syntactically, the compiler treats the array name as a pointer to the first element. You can reference elements using array syntax, a[n], or using pointer syntax, *(a+n), and you can even mix the usages within an expression.
When you pass an array name as a function argument, you are passing the “value of the pointer”, which means that you are implicitly passing the array by reference, even though all parameters in functions are “call by value”.
