15 Essential One-Dimensional (1D) Array Practice Questions in C

Arrays are one of the most important concepts in C programming. A one-dimensional (1D) array is a collection of elements stored in contiguous memory locations and can be accessed using an index. Mastering arrays is crucial for improving problem-solving skills and writing efficient programs.

To help beginners and programming enthusiasts, we have compiled 15 must-practice C programming questions on 1D arrays. These exercises will improve your understanding of array manipulation, traversal, searching, and sorting techniques.
