char数组初始化程序中的多余元素错误

我一直在尝试执行以下代码。.但是，我一遍又一遍地遇到相同的错误，我不知道为什么！

我的代码：

#include 
#include 
#include 
#include 

int main(void){

    int randomNum;
    char takenWords[4];
    char words[20]={"DOG", "CAT", "ELEPHANT", "CROCODILE", "HIPPOPOTAMUS", "TORTOISE", "TIGER", "FISH", "SEAGULL", "SEAL", "MONKEY", "KANGAROO", "ZEBRA", "GIRAFFE", "RABBIT", "HORSE", "PENGUIN", "BEAR", "SQUIRREL", "HAMSTER"};


    srand(time(NULL));

    for(int i=0; i<4; i++){
        do{
            randomNum = (rand()%20);
        takenWords[i]=words[randomNum];
        }while((strcmp(&words[randomNum], takenWords) == 0)&&((strcmp(&words[randomNum], &takenWords[i])==0)));
        printf("%s\n", &words[randomNum]);
    }
    getchar();
    return 0;
}

我已经计算了我在数组中输入的元素数量，并且它们不超过20个！

另外，为什么我总是收到“隐式转换丢失整数精度错误”的信息？

我猜您想创建一个指针数组而不是字符数组。

尝试这个：

#include 
#include 
#include 
#include 

int main(void){

    int randomNum;
    const char *takenWords[4];
    const char *words[20]={"DOG", "CAT", "ELEPHANT", "CROCODILE", "HIPPOPOTAMUS", "TORTOISE", "TIGER", "FISH", "SEAGULL", "SEAL", "MONKEY", "KANGAROO", "ZEBRA", "GIRAFFE", "RABBIT", "HORSE", "PENGUIN", "BEAR", "SQUIRREL", "HAMSTER"};


    srand(time(NULL));

    for(int i=0; i<4; i++){
        int dupe=0;
        do{
            randomNum = (rand()%20);
            takenWords[i]=words[randomNum];
            dupe=0;
            for(int j=0;j
