Ordering: largest value in an array in C

Build a C program that walks through an array and prints the largest value found.

lines

13

This program introduces a fundamental idea: to find the largest, start by assuming the first element is the largest, then compare with the rest.

That is why we do not declare largest = 0 or a random value: we use a value that is actually in the array.

Algorithm steps:

  1. Include <stdio.h>.
  2. Open main.
  3. Declare the array and the counter.
  4. Initialize largest with numbers[0].
  5. Loop from i = 1.
  6. Compare and update when needed.
  7. Print and return 0.

Pay attention to the order: an error declaring largest before the array breaks everything.
