Based on your knowledge of pointers and memory addresses, answer the questions following the code snippet below:

# include

int hcf ( int *x, int *y) { *x = *y;

int a = *x; int b = *y;

while (b != 0 ) { int tmp = b; b = a % b; a = tmp; } return a; } int main () { int a = 54 ; int b = 24 ;

int result = hcf(&a, &b);

return 0 ; }

Part a What will be the value of the result variable after calling hcf function?

Part b What will be the value of the variables a and b just before the program terminates?

Part c Briefly explain (in 1 or 2 sentences) your answers to part a and part b of this question.
