In the c programming language. How do I fix this code so that Valgrind shows no errors and memory leaks

#include #include struct 11 node int value: struct 11 node next ; / This overly complex code reads integers from stdin and places them in // a linked list. Then, it sums the items in the 11 t and prints int main) int user_inp: int sum int counter = Using a dummy head node struct 11 node front malloc (sizeof (struct 11 _node)) struct 11 node *current -front: inp) EOF) { (scanf("%d", current->next malloc (sizeof (struct current current->next while &user != - 11 node) ) ; - inp ; current->value current->next = countertt user NULL; Free (current-snext) :front- t tront-next) sumfront->value; //free (Ezont-Snext) free (front): / Eree (front) printf ("The sum of the inputs is %d.
