C++ 在C中将字符串插入到字符串的排序链表中

我不知道wordLenght是什么.但在任何情况下，在函数中使用此名称都没有意义，只会使函数变得不清楚，因为该名称没有在函数中定义.

不需要将函数分成两部分.这使得函数容易出错.

此外，While语句的条件

while (cursor->next != NULL && strcmp(newElem->data, cursor->data) < 0){

是不正确的.

如果此表达式

strcmp(newElem->data, cursor->data) < 0

计算结果为True，则需要中断循环.

还有一个打字错误

nodo* cursor = *head;

看来你的意思是

node* cursor = *head;

该函数可能如下所示

int insert( node** head, const char* word )
{
    node *newElem = malloc( sizeof( node ) );
    int success = newElem != NULL;

    if ( success )
    {
        success = ( newElem->data = malloc( strlen( word ) + 1 ) ) != NULL;

        if ( success )
        {
            strcpy( newElem->data, word );

            while ( *head != NULL && !( strcmp( word, ( *head )->data ) < 0 ) )
            {
                head = &( *head )->next;
            }

            newElem->next = *head;
            *head = newElem;
        }
        else
        {
            free( newElem );
        }
    }

    return success;
}

这是一个演示程序.

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

typedef struct node
{
    char *data;
    struct node *next;
} node;

int insert( node** head, const char* word )
{
    node *newElem = malloc( sizeof( node ) );
    int success = newElem != NULL;

    if ( success )
    {
        success = ( newElem->data = malloc( strlen( word ) + 1 ) ) != NULL;

        if ( success )
        {
            strcpy( newElem->data, word );

            while ( *head != NULL && !( strcmp( word, ( *head )->data ) < 0 ) )
            {
                head = &( *head )->next;
            }

            newElem->next = *head;
            *head = newElem;
        }
        else
        {
            free( newElem );
        }
    }

    return success;
}

void display( const node *head )
{
    for ( ; head; head = head->next )
    {
        printf( "\"%s\" -> ", head->data );
    }

    puts( "null" );
}

int main (void) 
{
    node *head = NULL;
    const char * data[] =
    {
        "7DJL", "-kiF", "8F4r", "7D7d", "-D7w", "-b7f"
    };
    const size_t N = sizeof( data ) / sizeof( *data );

    for ( size_t i = 0; i < N; i++ )
    {
        insert( &head, data[i] );
    }

    display( head );
}

程序输出为

"-D7w" -> "-b7f" -> "-kiF" -> "7D7d" -> "7DJL" -> "8F4r" -> null
