Hello and I'm sorry I don't speak English well.

I know this is repetitive But I Have a problem and i've never found the answer to my problem.

Shows this error whenever I compile this code by GCC : code :

const char* myFunction()
{
    static char array[] = "my string";
    return array;
}
char a[101];
a=myFunction();

Error :

StackOverFlow.c: In function ‘main’:
StackOverFlow.c:51:2: error: assignment to expression with array type
   16 | a=myFunction();
      |  ^

When I use the return value of the function directly within printf Function, it doesn't make an error.

printf ("%s", myFunction());

i dont know what's it's problem. sorry for Bad English.

return function c

That's because, in C, this is the same as assigning the pointer to array to a, but you have already "initialized" a.

I don't know what you're try to achieve, but if you want to copy the string, use

strcpy(a, myFunction());

or, if you want the pointer, try

const char *a;
a=myFunction(); //If you try using printf with a it will work.
