Robbie Hatley I needed a quick program called "random" that gives a random positive integer from n1 to n2. For example, if I type "random 38, 43", I want the program to print a random member of the set {38, 39, 40, 41, 42, 43}. Also, I read in my compiler's documentation the following: To get a random number in the ...
Hi, Please excuse me if this is not the right forum for this question. I would like to create a random permutation of a list of numbers. How can I do this in C? I was just going to draw a number from 1 to n. n is the number of items in the list and place the items in a ...

#include #include #include int main() { int randnum, high, low, num, i; srand( time(0) ); printf("Please enter the range (example 1 - 20): "); scanf("%d - %d",&low,&high); printf("\nHow many number do you wish to get?: "); scanf("%d",&num); for (i = 0;i < num;i++) { randnum = (int) (rand() / (RAND_MAX + 1.0) * (high - low + 1) ...
Here is my assignment: "Your program instead of always selecting a random integer between 1 and 1000 should ask the user for the maximum number, max, and choose a random integer between 1 and max." Here is what I have so far, it is due tomorrow please help: #include #include #include #include void InstrucUser(); int playAgain(); int ...
here is my program i cant get it to compile gives me parse error when i compile can someone take a look? #include #include #include #include void InstrucUser(); int playAgain(); int randInt(int max); int main() { int nummax, ans, i; srand(time(NULL)); printf("\n"); InstructUser(); printf("\n"); do { nummax = randInt(i); ans = playAgain(); } while (ans == 1) ...
Well, there is an easier and more efficient way to generate non-repeating random numbers. The algorithm is: generate all the (non random) sequential numbers you need, and put them into an array (any data structure would perhaps do, but an array is easy). Then shuffle the numbers in the array, randomly. Aha! Then take the randomized numbers, in order, by their ...
