WebJul 7, 2013 · int *array = new int [n]; It declares a pointer to a dynamic array of type int and size n. A little more detailed answer: new allocates memory of size equal to sizeof (int) * n bytes and return the memory which is stored by the variable array. WebThe syntax to declare a new variable in C++ is straightforward: we simply write the type followed by the variable name (i.e., its identifier). For example: 1 2 int a; float mynumber; These are two valid declarations of variables. The first one declares a variable of type int with the identifier a.
