sizeof is a
unary operator in the
programming languages C and C++. It
generates the
storage size of an
expression or a data type,
measured in the number...
-
expression cannot be the
operand of
sizeof. Therefore,
sizeof (int) * x is
interpreted as (
sizeof(int)) * x and not
sizeof ((int) * x). The

padding as part of the
array itself. It is
common to
allocate sizeof(struct) + array_len*
sizeof(array element) bytes. This is not wrong, but it may allocate...

- we can use realloc. int *arr = malloc(2 *

sizeof operator is an exception:
sizeof array yields the size of the
entire array (that is, 100
times the size of an int, and
