In this program
int *p creates a pointer variable of type int
malloc() allocates memory
Then *p = 10 assigns the value 10 to the address pointed by pointer p
The printf() statement prints the value at address pointed by p.
As p contains value 10, so 10 will be printed.
So option(1) is correct
16)
hello will be printed only once.
The reason is that there is a semicolon after the for loop, so the for loop will run 1000 times and then the hello statement will be printed.
If there was no semicolon after the for loop then the hello statement would have been printed 1000 times
So option(1) is correct

Malloc function
For the prelab assignment and the lab next week use malloc
function to allocate space (to store the string) instead of
creating fixed size character array. malloc function allows user to
allocate memory (instead of compiler doing it by default) and this
gives more control to the user and efficient allocation of the
memory space.
Example
int *ptr
ptr=malloc(sizeof(int)*10);
In the example above integer pointer ptr is allocated a space of
10 blocks this is same as creating...
