In, prime number logic can be used not only in C++ but in any programming language. From a small set of numbers to a big amount of numbers this logic can be used to find a set of prime numbers according to requirements within seconds without wasting any time in computer programming. Reco...
Prime number in C: Prime number is a number that is greater than 1 and divided by 1 or itself. In other words, prime numbers can't be divided by other numbers
it is not a prime numberif(number <=1)return false;// 2 is a prime numberif(number==2)return true;// If the number is even (other than 2), it is not a prime numberif(number %2 ==0)return false;// Calculate the square ...
, n); else printf("%d is not a prime number.", n); return 0; } Run Code Output Enter a positive integer: 29 29 is a prime number. In the program, a for loop is iterated from i = 2 to i < n/2. In each iteration, whether n is perfectly divisible by i is checked ...
In the main() function, a number is entered by the user. It is computing the number as sum of two prime numbers. cout << "Enter a number : \n"; cin >> num; for(i = 2; i <= num/2; ++i) { if (func(i)) { if (func(num - i)) { cout << num <...
