A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In C++, we can write a program to check whether a given number is prime or not. The program to find if a given number is prime or not in C++ can be written in several ways. Here, we will discuss two different approaches to write this program. Approach 1: Using a for loop In this approach, we will use a for loop to check if the given number is divisible by any number between 2 and n/2. If the number is divisible by any number in this range, then it is not a prime number. Otherwise, it is a prime number. Here is the code for the same: #include <iostream> using namespace std; int main() { int n, i; bool isPrime = true; cout << "Enter a positive integer: "; cin >> n; for (i = 2; i <= n / 2; ++i) { if (n % i == 0) { isPrime = false; break; } } if (isPrime) cout << n <...

The relationship between brothers-in-law (BILs) is one that holds a significant place in Indian culture and society. In India, brothers-in-law are not simply seen as extended family members, but rather as important allies and companions. The bond between BILs is seen as an extension of the relationship between brothers, and often holds a special significance in Indian families. In this essay, we will explore the cultural, social, and historical factors that have contributed to the special relationship between brothers-in-law in India. Historical and Cultural Background: The special bond between brothers-in-law in India can be traced back to the country's rich history and cultural heritage. In ancient India, the relationship between brothers-in-law was defined by the concept of "saṃdhi," which referred to the alliance between two families. This alliance was established through marriage and was seen as a way to strengthen ties between families and communities. The alliance ...
