c语言线性表怎么循环赋值

对于循环线性表的赋值，可以使用for循环来实现。以单向循环链表为例，代码如下：

#include <stdio.h>
#include <stdlib.h>

typedef struct Node {
    int data;
    struct Node * next;
} Node, *List;

List createList(int n) {
    if(n < 1) return NULL;
    List head, p;
    head = (List) malloc(sizeof(Node));
    head->next = NULL;
    p = head;
    for(int i = 0; i < n; i++) {
        int x;
        scanf("%d", &x);
        List temp = (List) malloc(sizeof(Node));
        temp->data = x;
        temp->next = head;
        p->next = temp;
        p = temp;
    }
    return head;
}

void printList(List head) {
    if(head == NULL) return;
    List p = head->next;
    while(p != head) {
        printf("%d ", p->data);
        p = p->next;
    }
}

void assign(List head, int value) {
    if(head == NULL) return;
    List p = head->next;
    while(p != head) {
        p->data = value;
        p = p->next;
    }
}

int main() {
    int n;
    printf("请输入线性表的元素个数：\n");
    scanf("%d", &n);
    List head = createList(n);
    printf("原始线性表：\n");
    printList(head);
    printf("\n请输入要赋的值：\n");
    int value;
    scanf("%d", &value);
    assign(head, value);
    printf("赋完值后的线性表：\n");
    printList(head);
    printf("\n");
    return 0;
}

这个程序的功能就是循环赋值，将单向循环链表的每个节点的值都赋成同一个数值。
