What is difference between new and new?

As interjections the difference between new and mew is that new is mew, meow, miaow while mew is a cat’s cry.

The new-expression returns a prvalue pointer to the constructed object or, if an array of objects was constructed, a pointer to the initial element of the array. The behavior is undefined if the value in the first dimension (converted to integral or enumeration type if needed) is negative.

A: The phrase “one-off” (it’s used as both an adjective and a noun) originated in Britain in the 1930s and appears to be gaining popularity here. It refers to something that is one of a kind or is occurring or being produced only once.

something that happens or is made or done only once: Will you be doing more talks in the future or was that just a one-off? SMART Vocabulary: related words and phrases.

In the first alternative ( delete object ), the value of the operand of delete may be a null pointer, a pointer to a non-array object created by a previous new-expression, or a pointer to a subobject (1.8) representing a base class of such an object (Clause 10). If not, the behavior is undefined. So a “placement new” does count as a new-expression.

Placement new is a variation new operator in C++. Normal new operator does two things : (1) Allocates memory (2) Constructs an object in allocated memory. Placement new allows us to separate above two things. In placement new, we can pass a preallocated memory and construct an object in the passed memory. new vs placement new

Placement new allows us to separate above two things. In placement new, we can pass a preallocated memory and construct an object in the passed memory. Normal new allocates memory in heap and constructs objects tehre whereas using placement new, object construction can be done at known address.

If the new-expression begins with the optional :: operator, as in ::new T or ::new T[n], class-specific replacements will be ignored (the function is looked up in global scope ). Otherwise, if T is a class type, lookup begins in the class scope of T .
