  1. Users of this program can carry out addition, subtraction, multiplication, and division, among other fundamental arithmetic operations.<\/li>\n\n\n\n
  2. Two numbers will be entered by the user, who will also select an operation by typing a symbol (+, -, *, \/).<\/li>\n\n\n\n
  3. To carry out the action in accordance with the user’s selection, we’ll employ a switch-case statement.<\/li>\n<\/ol>\n\n\n
