Maybe you are thinking of a function pointer. This compiles without error in C, and on SoloLearn it prompts you for input without any reference to x in main(). Other compilers likely would optimize and remove matr_size() and x as unreachable/unused code.
int (*x)()=&matr_size;
int main() {
//printf("%d", x());
return 0;
}

Every code must be inside main function. If you mean this,
int x;
scanf ( x ); // is not allowed
main()
{
printf (x);
}
it is not possible.

Can't we even take through pointers by using dynamic memory allocation I have seen this in some articles I haven't got the complete information there
