Unlocking the Power of C++: A Deep Dive into Prime Number Generation
When it comes to mastering C++ programming, understanding the intricacies of conditional statements and loops is crucial. In this article, we’ll explore two fascinating examples that showcase the capabilities of C++ in generating prime numbers between two intervals.
The Foundation: C++ Conditional Statements
Before we dive into the examples, it’s essential to have a solid grasp of C++ conditional statements, including if
, if...else
, and nested if...else
constructs. These statements form the backbone of decision-making in C++ programming.
Example 1: Unleashing Prime Numbers with a While Loop
Imagine a program that displays all prime numbers between two user-defined intervals. This C++ program employs a while
loop that iterates (high - low - 1)
times, checking whether each number in the range is prime or not. With each iteration, the value of low
increments by 1 until it reaches high
. But what happens when the user enters the larger number first? The program doesn’t work as intended! Fear not, for we can solve this issue by simply swapping the numbers if the user enters them in the wrong order.
Output: Prime Numbers Between Two Intervals
Take a look at the output of this program:
Enter lower limit: 10
Enter upper limit: 20
Prime numbers between 10 and 20 are: 11, 13, 17, 19

Example 2: Displaying Prime Numbers with a Twist
What if we want to display prime numbers between two intervals, but with a user-defined function? This program tackles the challenge head-on, showcasing the power of C++ in generating prime numbers even when the larger number is entered first.
Output: Prime Numbers with a User-Defined Function
Check out the output of this program:
Enter lower limit: 20
Enter upper limit: 10
Prime numbers between 10 and 20 are: 11, 13, 17, 19
