如何定义和初始化一个struct内的字符串数组？ [英] How do I define and initialize an array of strings inside of a struct?

问题描述

typedef struct mobiltelefon {
    char herstellername[HLEN];
    double displaydiagonale;
    aufloesung_t aufloesung;
    char standards[NUMBER_OF_STRINGS][STRINGLENGTH+1] = {"GPRS", "EDGE", "HSDPA", "HSUPA", "HSPA",
"LTE"};
} telefon_t;

我不断收到预期的错误;在声明列表。

推荐答案

修改

char (*standards[6])[5] = {{"GPRS"}, {"EDGE"}, {"HSDPA"}, {"HSUPA"}, {"HSPA"}, {"LTE"}};

到

char standards[6][6] = {{"GPRS"}, {"EDGE"}, {"HSDPA"}, {"HSUPA"}, {"HSPA"}, {"LTE"}};

一个简单的例子：

A quick example:

#include <stdio.h>

int main(int argc, char *argv[])
{
    int i;
    char standards[6][6] = {{"GPRS"}, {"EDGE"}, {"HSDPA"}, {"HSUPA"}, {"HSPA"}, {"LTE"}};
    for(i=0;i<6;i++)
        printf("%s\n",standards[i]);
    return 0;
}

请注意字符标准[6] [5] 是错在你的情况为你的二维数组中最长的字符串为 HSDPA 和 HSUPA 这是一个长度为5，则需要多一个字节终止'\\ 0'字符。

Kindly note char standards[6][5] is wrong in your case as the longest string in your 2D array is HSDPA and HSUPA which is of length 5, you will need one more byte for terminating '\0' char.
