Efficient Integer and Score Processing in C: Functions and Arrays

This guide highlights essential C programming techniques for processing integers and scores using arrays and functions. It covers input handling for ten integers, calculation of average scores, and the implementation of utility functions like calculating sums and setting array values to zero. Each function is designed for clarity and efficiency, allowing programmers to grasp fundamental C concepts related to input/output and array manipulation. Ideal for beginners looking to solidify their understanding of data handling in C.
