How to store a array in another array in C

Question

So I want store an array named buffer into an array into an array called first_line That is what I tried:

first_line = buffer;

It's obvisly that this does not work. I know that an array has many parts but how do I store it all together in one variable?

I'm a totally beginner in C and dont know what I am doing could someone help me?

I got the code from codeforwin.org/2018/01/… line 43 you will see it — Tim

You haven't shown enough code for us to accurately help, but I'll say this much. Let's assume your buffer array stores chars. Then it would be of type char []. If you want to store an array of char [], then that array would be of type char *[]. Provide some code and we can help ensure you allocate memory for these types correctly. — h0r53

Arrays do not have the assignment operator.

If you have character arrays that store strings then you can use for example functions strcpy , strncpy or memcpy declared in header <string.h> to copy a string from one array into another.

For example

#include <string.h>

//...

char s1[] = "Hello";
char s2[sizeof( s1 )];

strcpy( s2, s1 );

To copy arrays that do not store strings you can use either function memcpy or some kind of a loop to copy element by element from one array in another.
