The following C structure has been defined: struct int_node { int value: struct int_node * next: }: Write a function void print _int _list that is given a single argument that is a pointer to a struct int _ node. The function should print the values in the linked of integers indicated by that pointer to the standard output and continue to follow the linked list until a NULL pointer is found. Each integer should be printed as a decimal number, one entry per line. You should not provide the main() function -- only implement the print _ int _ list(struct int _ node * ptr) function as described above
