如何修复它以获得H作为输出？ [英] How do I fix it to get H as output?

问题描述

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char* element[] = {"Hydrogen","Helium","Lithium","Beryllium","Boron","Carbon","Nitrogen","Oxygen","Fluorine","Neon"};

	char j[2] = element[0];
	printf("%c\n",j[0]);

    return 0;
}

我的尝试：

What I have tried:

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char* element[] = {"Hydrogen","Helium","Lithium","Beryllium","Boron","Carbon","Nitrogen","Oxygen","Fluorine","Neon"};

	char j[] = element[0];
	printf("%c\n",j[0]);

    return 0;
}

推荐答案

试试这个：

Try this:

int main()
    {
    char* element[] = {"Hydrogen", "Helium", "Lithium", "Beryllium", "Boron", "Carbon", "Nitrogen", "Oxygen", "Fluorine", "Neon"};
    char* j;
    j = element[0];
    printf("%c\n",j[0]);
    return 0;
    }

元素是一个指向字符的指针数组。

所以访问数组元素，你需要一个指向角色的指针：

element is an array of pointers to character.
So to access an element of the array, you need a pointer to a character:

char* j;

#include <stdio.h>

int main()
{
    char* element[] = {"Hydrogen","Helium","Lithium","Beryllium","Boron","Carbon","Nitrogen","Oxygen","Fluorine","Neon"};

  printf("%c\n",**element);

  return 0;
}
