我无法将 char 字符串分配给 char 数组 [英] I am having trouble assigning a char string to a char array

问题描述

这就是我现在所拥有的.

This is what I have now.

void insert(char Table[][81], char Key[81]){
    int index;
    index = search(Table, Key); 
    // This is another function used to find an empty 'slot'
    // in the table
    if(Table[index] == '')
    Table[index] = Key; 
    // <-- This is the line that contains some sort of error.
    else
    printf("ERROR: Key already in Table
");
}

它抛出的错误是:

从类型char *"分配给类型char[81]"时类型不兼容.

incompatible types when assigning to type 'char[81]' from type 'char *'.

我不知道如何修复或抛出此错误的原因.如果有人需要我的程序中的更多信息来得出结论，请告诉我.

I am at a loss as to how to fix or why this error is being thrown. If anyone needs more info from my program to draw a conclusion please let me know.

推荐答案

你不能分配数组，但你可以使用 strcpy() 或 memcpy() 改为:

You cannot assign arrays but you can use strcpy() or memcpy() instead:

if (Table[index][0] == '')
    memcpy(Table[index], Key, sizeof(Key));
else
    printf("ERROR: Key already in Table
");
