Thread: Copying an array string into a struct

Suppose we had:

Code:

char string[25] = {"hi","ok"};

can we now copy it into a variable in a struct declared as:

Code:

char alias[25];

like this:

Code:

user->alias = string[2];

I ask because, I have an array of 104 elements with something similar to that displayed in char string, and I'm trying to copy those elements into a struct variable similiar to char alias, when i do copy it and I print it out, i get strange results, it's like everything was copied but got unorganized and mixed up

Code:

{"hi","ok"}

is initializer list for array of 2 strings

user->alias = string[2]; - no you cannot copy strings like this

string[2] is one character in your sample
if string would be defined as array of two strings - index 2 is out of bounds, correct indexes are 0 and 1

and for copying strings C uses strcpy function

Yea it was just an example, the index in the program is correct, but thanks for letting me know, i think what was causing the problem was the incorrect copy of strings.
