C++: What is the difference between new and malloc?

new — C++ operator. malloc — C function.

1int* p1 = new int(10);  // Constructor
2delete p1;
3
4int* p2 = (int*)malloc(sizeof(int));  // No constructor
5free(p2);

new:

• Calls constructor.
• Returns typed pointer.
• Throws on failure.

malloc:

• No constructor.
• Returns void*.
• Returns null on failure.
