Consider the following pseudo
code,
Method func()
{
PRINT “This is recursive
function"
func()
}
Method main(
{
func()
}
What will happen when the
above snippet is executed?
int *p; where p is a null pointer
when:
Pointers
There follows a program with headers omitted.
However, a question mark needs to be replaced with a number in order for the program to compile and run.
int main(void){
int
a 1;
int
b = 2;
int
C = 3;
int d &c;
int
*e = &b;
int *+ &e;
***= ?;
int **g = &d;
d = &a;
**g- c;
e = &c:
4= a + b;
printf("a = Xdb = Xd c = Xd", a, b, c);
If the value for printed for c is 9
Then the value chosen for the ? was
the value printed for a is
and the value printed for b is

- Art.java In this part you will create a program Art.java that produces a recursive drawing of the design attached in the picture. Requirements Art.java must take one (1) integer command-line argument n that controls the depth of recursion. Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.) You may not change the size of the drawing window (but you may change the scale). Do not add sound. Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions. Optionally, you may use the Transform2D library you implemented in Part 1. You may also define additional geometric transforms in Art.java, such as sheer, reflect across the x- or y- axis, or rotate about an arbitrary point (as opposed to the origin). Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. call…arrow_forwardIf integer pointer aPtr is to point at a data item whose value may not change it must be declared as ... A. const int * const aPtr; B. int *aPtr; C. int *const aPtr; D. const int *aPtr;arrow_forwardIn C In this problem, you will recreate one of the truly great moments in history, namely the classic race of the tortoise and the hare. You will use random number generation to develop a simulation of this memorable event and use pointers to store / track the position of the two race contestants. Our contenders begin the race at “square 1” of 70 squares. Each square represents a possible position along the race course. The finish line is at square 70. The first contender to reach or pass square 70 is rewarded with a pail of fresh carrots and lettuce. The course weaves its way up the side of a slippery mountain, so occasionally the contenders lose ground. There is a clock that ticks once per second. With each tick of the clock, your program should adjust the position of the animals according to the rules shown in the table below. Implement the “race course” as an integer array containing the numbers from 1 to 70. Implement the positions of the tortoise and the hare as pointers,…arrow_forward
- What is void pointer? Give Example code ?arrow_forwardpointers as Arguments:In the C programming language there is no pass-by-reference syntax to passa variable by reference to a function. Instead a variable is passed by pointer(just to be confusing, sometimes passing by pointer is referred to as pass byreference). This Practice Program asks you to do the same thing as C.Here is the header for a function that takes as input a pointer to an integer:1. void addOne (int ∗ptrNum )Complete the function so it adds one to the integer referenced by ptrNum.Write a main function where an integer variable is defined, give it an initialvalue, call addOne, and output the variable. It should be incremented by 1.arrow_forwardIn C++, When an array is passed to a function as a pointer, the function doesn't know the size of the array. List 3 ways to handle this problem.arrow_forward
