# Introduction In this lab, you will learn how to implement the Sieve of Eratosthenes algorithm in C to find prime numbers up to a given upper limit. You will start by reading the upper limit from the user, then mark multiples of prime numbers as non-prime, and finally print all the prime numbers found. This lab covers concepts in number theory and discrete mathematics using the C programming language. The lab consists of three main steps: reading the upper limit, marking multiples as non-prime, and printing all prime numbers. By following these steps, you will gain a deeper understanding of the Sieve of Eratosthenes algorithm and its implementation in C.
