WebIf the input number is either 0 or 1, then the value of is_prime is set to false. Else, the initial value of is_prime is left unchanged. Then, the for loop is executed, which checks whether the number entered by the user is perfectly divisible by i or not. for (i = 2; i <= n/2; ++i) { if (n % i == 0) { is_prime = false; break; } }
