在 C 中为字符数组分配一个值 [英] Assigning char array a value in C
问题描述
有什么区别:
char fast_car[15]="Bugatti";
和
char fast_car[15];
fast_car="Bugatti";
因为第二个导致编译错误:
Because the second one results with compile error:
错误:从类型分配给类型‘char[15]’时类型不兼容‘字符*’
error: incompatible types when assigning to type ‘char[15]’ from type ‘char *’
虽然第一个工作正常.将字符串放在数组中与数组初始化不同的位置会很有帮助.
While the first one works fine. Putting a string in array in different place than array initialisation would be helpful.
推荐答案
第一个是初始化,第二个是赋值.由于数组在 C 中是不可修改的值,因此您无法为它们分配新值.
The first is an initialization while the second is an assignment. Since arrays aren't modifiable values in C you can't assign new values to them.
请注意,您可以修改数组内容,只是不能说fast_car = ...
.所以内容是可以修改的,数组本身不是.
Mind you, you can modify array contents, you just can't say fast_car = ...
. So the contents are modifiable, the arrays themselves are not.
对这些截然不同的概念使用相同的符号 =
是值得商榷的.
Using the same symbol =
for these widely different concepts is of debatable value.
