Exercice 1 : Mot du jour

Écrire un programme qui retourne un mot parmi une liste de mot, de façon aléatoire.

#include <time.h>
#include <stdlib.h>

char *words[] = {"Albédo", "Bigre", "Maringouin", "Pluripotent", "Entrechat",
    "Caracoler" "Palinodie", "Sémillante", "Atavisme", "Cyclothymie",
    "Idiosyncratique", "Entéléchie"};

#if 0
    srand(time(NULL));   // Initialization, should only be called once.
    size_t r = rand() % sizeof(words) / sizeof(char*); // Generate random value
#endif

Solution

#include <time.h>
#include <stdlib.h>

char *words[] = {
    "Albédo", "Bigre", "Maringouin", "Pluripotent", "Entrechat",
    "Caracoler" "Palinodie", "Sémillante", "Atavisme", "Cyclothymie",
    "Idiosyncratique", "Entéléchie"};

int main(void)
{
    srand(time(NULL));
    puts(words[rand() % (sizeof(words) / sizeof(char*))]);
}
