hi @abhay170

there are many mistakes in the code

i have updated a few and those commented need to be updated by you
you had declared functions within int main() which is not allowed in c++ or c
refernce binding was not done properly

u need to update the code:
write what the display function does, that is define the function u have just given a declaration and called it inside main which is wrong
// insertion_at_beg(data);
// insertion_at_end(data);
have the same problem u have just declared them and no definition has been provided.

Please understand the basics of C language as i see that u are unfamiliar with the basicx.
please go through the following link to learn to create a linked list in c language

ur updated code
