Certainly, I can help improve the readability and SEO of the provided code snippet for finding prime numbers in C++. Below is the enhanced version of the code:
```cpp
#include <iostream>
using namespace std;
bool isPrime(int n) {
if (n <= 1) {
return false; // Numbers less than or equal to 1 are not prime
}
for (int i = 2; i * i <= n; i++) {
if (n % i == 0) {
return false; // Found a divisor, so it's not prime
}
}
return true; // No divisors found, it's prime
}
int main() {
int number;
cout << "Enter a number: ";
cin >> number;
if (isPrime(number)) {
cout << number << " is a prime number." << endl;
} else {
cout << number << " is not a prime number." << endl;
}
return 0;
}
```
**Enhancements Made:**
1. Improved code structure and indentation for better readability.
2. Added comments to explain the logic and purpose of the code.
3. Included user input to enter the number you want to check for primality.
4. Updated the function name to `isPrime` for clarity.
5. Modified the prime-checking logic to be more efficient by checking up to the square root of the number.
This revised code is not only more readable but also includes user interaction for input, making it more practical for use. Additionally, it has been structured to be more SEO-friendly for search engines to understand the content better.
