CSE 2312 - Assignments - Assignment 9

The assignment will be graded out of 100 points. Submit your source code for each task, in files called task1.s, task2.s, and so on. Each source file should include ONLY the functions that you are defining for that task, not the main program. Submit your solutions to Blackboard before the deadline. You will be able to revise your answers until the deadline with no penalty.

Task 1 (10 points)

int foo(int a, int b)
{
  if (a == b) return 0;
  return b - a + 10;
}

Task 2 (15 points)

int foo(int a, int b)
{
  int result = 0;
  int i;
  for (i = 20; i <= 30; i++)
  {
    if (i == 24) result += 20;
    else if (i == 27) result = result * 2;
    else result = result + a + 3*b;
  }

  return result;
}

Task 3 (15 points)

int foo(int a, int b)
{
  if (a > b) return 0;
  if (a == b) return b;
  return a + foo(a+1, b);
}

Task 4 (20 points)

int foo(int a, int b)
{
  int c = a+3;
  int d = c*5;
  int e = c+d;
  int f = e*d;
  int g = f - c;
  return a+b+c+d+e+f+g;
}

Task 5 (20 points)

int foo(int a)
{
  int result = 0;
  if (a <= 0) return 0;
  while(a > 0)
  {
    int b = a % 2;
    a = a / 2;
    result += b; 
  }

  return result;
}

Task 6 (20 points)

• Takes an integer as an argument.
• If the argument is less than or equal to zero, the function returns -2.
• If the argument is greater than zero:
  • If there exists an integer N such that the argument is equal to 2^N, the function should find that N and return N.
  • Otherwise the function returns -1.
