Study Notes

Manipulating a List

  • Lists can be filled, searched, and modified
  • Filling a list often uses loops
  • Example:
    • Counter i initialized to 1
    • Loop runs until i is less than or equal to 5
    • Prompts user to enter value for cell v[i]
    • Increments i after each input
  • Displaying list content
    • Loop runs until i is less than or equal to 5
    • Displays the value of v[i] for each i
  • In a loop, counter i acts as both a counter of the loop and a pointer for cells in the list v
