Flashcards

Planter Value (Initial)

Calculates (3 * 3 + 2) / 3 using integer arithmetic.

Planter Value (Modulo)

Sets planter to the remainder of 9 / 4.

Planter Value (Arithmetic)

Calculates 2 + 2 * 3 / 6 using integer arithmetic and sets planter to result.

planter += 2; planter *= 2; effect

Increments planter by 2, then multiplies the result by 2.

printArray(planter) issue

Attempts to print an array representation of single integer, which isn't possible given the printArray function expects an integer array.

Study Notes

  • The C program includes three functions: flower, stem, and main, as well as printArray, which is called but not defined
  • The main function initializes an integer variable planter and an integer array garden with values {2, 3, 1, 7}
  • An integer variable i is initialized to 0 and used as a loop counter
  • planter is assigned a series of values through arithmetic operations:

Planter Variable Changes

  • Initially, planter is assigned the value of (3 * 3 + 2)/3 which evaluates to (9 + 2)/3 = 11/3 = 3 (integer division)
  • planter then becomes the remainder of 9 % 4, which is 1
  • Next, planter is assigned the value of 2 + 2 * 3 / 6, which is 2 + 6 / 6 = 2 + 1 = 3
  • planter is directly assigned the value 6
  • The value of planter is incremented by 2 (planter += 2), resulting in planter = 8
  • planter is then multiplied by 2 (planter *= 2), resulting in planter = 16
  • The printArray function is called with planter as its argument, but due to type mismatch (passing an int where an int[] is expected) the behaviour is undefined. This is compiled without issue.
  • The printArray function is called with the garden array as its argument, though this function is not defined.

For Loop

  • A for loop iterates as long as i is less than planter (i < planter).
  • The loop calls the flower function, passing the current value of i as the argument colour
  • The returned value from flower(i) is not stored or used
  • Inside the flower function, the stem function is called with the argument colour + 2, but the returned value is not stored or used

Flower Function

  • The flower function takes an integer colour as input.
  • Inside flower, the stem function is called with colour + 2 as its argument,

Stem Function

  • The stem function takes an integer leaf as input.
  • stem returns the value of leaf * 3

Program Issues

  • The printArray function is called but not defined, resulting in a linker error unless a suitable definition exists in another compilation unit.
  • There is a type mismatch when calling printArray(planter), as printArray expects an integer array, but an integer is passed.
  • Values returned by flower and stem are never used
  • The array garden is defined but its elements are not referenced after being printed via the printArray call
