＆QUOT;字典＆QUOT;未申报 [英] "Dictionary" Undeclared

问题描述

我试图创造C.基本上，用户创建自己的字典，输入一个单词，然后定义字典。我已经创建其中显示词典的函数，表示各条目和它的定义。不过，我得到这个错误：

I'm trying to create a dictionary in C. Basically, the user creates the dictionary himself, inputting a word and then a definition. I've created a function where the dictionary is displayed, showing each entry and its definition. However, I'm getting this error:

错误：'词典'未声明（第一次使用此功能使用）

error: ‘dictionary’ undeclared (first use in this function)

下面是我写的code：

Here's the code that I've written:

#include <stdio.h>

void display (char *array) {
    int i;

    for (i=0; i<11; ++i)
        printf("%s %s", dictionary[i][0], dictionary[i][1]);
}

int main(void) {
    char *dictionary[10][2];
    int command;
    int i;

    while (command != 3) {
        printf ("1. Define or 2. Lookup or 3. Exit");
        scanf ("%d", &command);

        if (command == 1) {
            for (i=0; i<11; ++i) {
                printf("Please enter a word to define:");
                scanf("%s\n", dictionary[i][0]); 
                printf("Please enter its definition:");
                scanf("%s", dictionary[i][1]);
                break;
            }
        }

        if (command == 2)
            display(dictionary);
    }

    return 0;
}

有人能解释我在做什么错了？

Can someone explain what I'm doing wrong?

推荐答案

字典是在不同的函数的局部变量。结果
您的参数被命名为阵列。

dictionary is a local variable in a different function.
Your parameter is named array.
