How to generate N random numbers between min and max into an array with C

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
  
#define SIZE 7
   
int getRandom(const int min, const int max) {
    return (rand() % (max - min + 1)) + min; 
}
  
void GenerateNRandomNumbers(const int N, int array[], const int min, const int max) {
    for (int i = 0; i < N; i++) {
        array[i] = getRandom(min, max);
    }
}
  
int main(void) {
    srand(time(NULL));
    int array[SIZE];
    const int N = SIZE;
      
    GenerateNRandomNumbers(N, array, 1, 30);
      
    for (int i = 0; i < N; i++) {
        printf("%d ", array[i]);
    }
   
    return 0;
}
