c - 从不兼容的指针类型和结构数组进行初始化

Question

我目前正在学习 C，但在理解指针和结构数组方面遇到了一些麻烦。这是我编写的一个简单程序:

#include <stdio.h>

typedef struct {                                        /* Define the structure Pokemon that contains a nickname, type and level*/
    char nickname[11];
    char type[11];
    int level;
} Pokemon;

int main(void) {

    char nickname[11];
    char type[11];
    int level;

    for (int i = 0; i < 3; i++) {                      /* Iterate through the loop three times, each time create a new pokemon */
        printf("Pokemon %i \n", i);
        printf("Nickname: ");
        scanf("%s", &nickname);
        printf("Type: ");
        scanf("%s", &type);
        printf("Level: ");
        scanf("%i", &level);

        Pokemon * poke = {nickname, type, level};                /* Insert the pokemon into the array of Pokemon */

        printf("%s, %s, %i", poke->nickname, poke->type, poke->level);
    }
}

基本上，我想为具有这三个特征的口袋妖怪创建一个结构。在主要功能中，我希望用户输入 3 个口袋妖怪的特征，然后创建具有这三个特征的结构口袋妖怪实例，并将这些特征打印到标准输出。使用此代码，它可以编译，但我收到警告:

pokemon.c:33:9: warning: initialization from incompatible pointer type [enabled by default]
pokemon.c:33:9: warning: (near initialization for ‘poke’) [enabled by default]
pokemon.c:33:9: warning: excess elements in scalar initializer [enabled by default]
pokemon.c:33:9: warning: (near initialization for ‘poke’) [enabled by default]
pokemon.c:33:9: warning: excess elements in scalar initializer [enabled by default]
pokemon.c:33:9: warning: (near initialization for ‘poke’) [enabled by default]

不确定这是为什么 - 我想这与我设置的指针有关，但正如我所说，我仍在努力解决这个问题。

我还想将每个 pokemon 实例放入一个包含三个 pokemon 的数组中。到目前为止，我得到了这个:

Pokemon p [3];

// This bit inside the for loop and after the 'poke' struct instantiation
p[i] = poke;
printf("%s,%s,%i inserted\n", poke.nickname, poke.type, poke.level );

但这并不想编译 - 我想这是另一个指针错误。

Answer 1

Pokemon p[3];
...
Pokemon poke;
strncpy(poke.nickname, nickname, sizeof(poke.nickname));
strncpy(poke.type, type, sizeof(poke.type));
poke.level = level;
p[i] = poke;

编辑:修复临时结构初始化。
