About Random numbers!
How to generate Random numbers? We can generate Random numbers by using rand() or random() function. This is defined in "stdlib.h". Example below illustrates to generate Random number. #include #include int main() { int i; int num; int range; num = random(); // or else use rand() printf("\nnum : %d", num); num = random(); // or else use rand() printf("\nnum : %d", num); return 0; } But everytime you run this program, it will give same series. Starting number is decided by the seed, which is always initialized by 0 for rand(). If we want a different series, we need to initiate seed value using srand(int). That means, for a particular seed value, we always get one series. srand(int); Good way of initiating seed value is by using time, so that everytime we get different value for seed. See the example below: #include #include #include int main() { int i; int num; int range; time_t seconds; ti...
