Ordering: position search in C

Build a C program that searches for a value in an array and reports the position where it appears, breaking the loop as soon as it is found.

lines

This test is a conceptual leap: it combines sequential search, a sentinel (-1), break and a final if/else.

Check the mental order:

  1. Prepare the data: array, counter, target value and position = -1.
  2. Loop with for.
  3. Inside the for, an if that checks the match, saves the position and does break.
  4. After the loop, an if/else that decides the message based on whether position changed.

Key detail: the final if/else goes outside the for, not inside. If you put it inside the loop, it runs every iteration and the program lies.

Algoritmo a ordenar

Order the lines to search for a value in an array. Use position = -1 as a sentinel, break when found, and then report the result with an if/else.
