When sending a multidimensional array to a function, why are you required to specific all dimension sizes except the leftmost one?

Since all arrays in memory are single dimension arrays, the function needs to know how far to jump forward in that list.

What does this Python code do

num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
if num1 > num2:
    print(f"The first number ({num1}) is greater than the second number ({num2}).")
elif num2 > num1:
    print(f"The second number ({num2}) is greater than the first number ({num1}).")
else:
    print("Both numbers are equal.")

Get 2 numbers from the user and determines which is greater

What does this C++ code do

#include 
int main() {
    int number;
    std::cout << "Enter a integer: ";
    std::cin >> number;
        int result = 1;
    for (int i = 1; i <= n; ++i) {
        result *= i;
    }
        std::cout << result << std::endl;
    return 0;
}

Finds the factorial of the number input by the user

600

What does this Onyx code do?

use core {*}
main :: () {
    n := read_line() |> conv.parse(u32, _)!
    v := 0
    for i in 1 ..= n do v += i
    printf("Value: {}\n", v)
}

Finds the sum from 0 until (and including) the number input by the user

800

What does this Elixir code do / output

IO.gets("> ")
  |> String.trim()
  |> String.split(" ")
  |> Enum.map(&String.to_integer/1)
  |> Enum.max()
  |> IO.puts()

User types in a list of numbers that are space separated and the program outputs the max

1000

What does this Haskell code output

foo :: [Int] -> Int 
foo [] = 0 
foo (x:xs) = x + foo xs 
main :: IO () 
main = do 
  let numbers = [1, 2, 3, 4, 5] 
  print (foo numbers)

prints the sum of the numbers (15)
