I am studying C Language I need some explanation about a code segments,
int *p;
p = (int *) malloc(sizeof(int));
What does the (int *) means and whats really happening when you execute the above Code?
(int *)is a so called cast operator. It is used to convert the value on the right side of the operator to the type enclosed in parenthesis.Here, it is used to convert the
void *pointer returned bymalloc()to anint *, i.e. a pointer to an integer.This is a very bad usage, and you should not do it.
