What is prime number C program?
Prime Number Check Program in C Program: #include main() { int n, i, c = 0; printf(“Enter any number n:”); scanf(“\%d”, &n); //logic for (i = 1; i <= n; i++) { if (n \% i == 0) { c++; } } if (c == 2) { printf(“n is a Prime number”); } else { printf(“n is not a Prime number”); } return 0; }
What are prime numbers example?
