Invalid Array Assignment/Array of Struct - Tralen - Sep 9, 2017
EDIT: PROBLEM SOLVED JUST HAD TO USE STRCPY() THANKS FOR THE HELP!
It has been a while since i've messed with structs in C so the solution to my problem may be very simple but I just can't figure it out. I would usually ask questions like this on stackexchange but the people over there are jerks so I figured I would rely on this community instead.
so I have the following struct declared
Code
typedef struct list{
char name[256];
int size;
}list;
//I then init the 2 with integers I get from figuring out the # of files in a directory
list directories[numOfDirectories];
list files[numOfFiles];
//then inside of a loop I try assigning values to them.
directories [dirCount++].name = de->d_name;
files[fileCount++].name = de->d_nameThe last 2 lines are the one where the Invalid Array Assignment error is coming up. I don't think its a problem with the dirent struct (which is assigned to de) as i've used it to print the names of the files. Here is a link to the entire code, thanks in advance for any help.

What is your compiler command line? VLA's are C99+ only.

i just do c++ main.cpp on linux mint

C++ doesn't have VLA's either - it's a C only feature. You need to allocate a pre-defined amount on the stack or use the heap.

I figured it out, i had to use strcpy() instead of setting 2 char arrays equal to each other. Thanks for the help though.

That's not even closely related to the original question you asked about the arrays.

I just gave the error message and my code. Error message was invalid array assignment, and that is what solved it. What did you think my original question was?

You mentioned compiling as C++ and I didn't scroll down to look past the array declarations. You shouldn't be using strcpy, you should be using strncpy.
