I was trying to print a linked list of first 10 elements of linked list. But I face error while printing or while inputting

Question

What can be the main issues in this code.

This is the case when I try to print first two elements: https://drive.google.com/file/d/1Ve9HH4tzBmWGZsW5lHjNrTXtHNh1w33o/view?usp=sharing

This is the case while inputting the third element. https://drive.google.com/file/d/1NA-Oyh44aA4C_CtGXLbbM_m5DgEUnOQn/view?usp=sharing
