When calling malloc, you gave the memory a type. For example,

int *pInt = malloc(sizeof(int));

pInt is a pointer to an int, and points to the memory. In other words, the
memory is an int and can be adressed as such. For example:

*pInt = i;

copies the value i to the malloc-ed memory.
If you want to move larger pieces of data, have a look at memmove, or memcpy.
