Uncovering the Secrets of Prime Numbers
Prime numbers have fascinated mathematicians for centuries, and their unique properties continue to intrigue us today. A prime number is a positive integer that is divisible only by 1 and itself, making them a fundamental building block of mathematics. Examples of prime numbers include 2, 3, 5, 7, 11, 13, and 17.
The Power of C Programming
To understand prime numbers, we need to harness the power of C programming. Specifically, we’ll utilize the if…else statement, for loop, and break and continue statements to create a program that checks whether a number is prime.
Cracking the Code
Our program uses a for loop to iterate from i = 2 to i < n/2, where n is the number we’re checking for primality. In each iteration, we use an if statement to check whether n is perfectly divisible by i. If it is, we set a flag to 1 and terminate the loop using the break statement. This ensures that we don’t waste computational resources on unnecessary iterations.
The Flag System
We initialize the flag as 0 at the start of our program. If n is a prime number after the loop, the flag remains 0. However, if n is a non-prime number, the flag is set to 1, indicating that it’s not a prime number.
