Question3 (a) Provide a single line of C++ code that will declare an integer pointer variable named x [2 marks] (b) You have variable c declared as int c; Give the single line of C++ code that will assign the integer that is pointed to by x (from above) to c. [2 marks] (c) Now provide the C++ code that will assign the address of c to x. [2 marks] (d) You may assume that x is now pointing to an allocated and initialised block of 10 integers. Write a for loop that uses pointer arithmetic to print out the contents of this block. 4 marks] (e) What is a segmentation fault? [2 marks]
