Question

#import <stdio.h>
#import <stdlib.h>

typedef struct Video {
char *name;
int unique_views;
} Video;

typedef struct Viewer {
char *username;
Video *watched_videos;
int watched_videos_size;
} Viewer;

int count_views(Viewer **viewers, int viewers_size, char *video_name)
{
//在此处实现
return -1;
}

#ifndef RunTests
int main()
{
Video videos[] = { {.name = "Soccer", .unique_views = 500},
{.name = "Basketball", .unique_views = 1000} };
Viewer viewer = {.username = "Dave", .watched_videos = videos,
.watched_videos_size = 2};

Viewer *viewers[] = { &viewer };
printf("%d", count_views(viewers, 1, "Soccer")); /* should print 1 */

}
#endif

Answer 1

这main里的不是C代码吧

#include <stdio.h>
#include <string.h>
typedef struct Video {
    char *name;
    int unique_views;
} Video;

typedef struct Viewer {
    char *username;
    Video *watched_videos;
    int watched_videos_size;
} Viewer;

int count_views(Viewer **viewers, int viewers_size, char *video_name)
{
    int i,j,count=0;
    for(i=0;i<viewers_size;i++)
    {
        for(j=0;j<viewers[i]->watched_videos_size;j++)
        {
            if(strcmp(video_name,viewers[i]->watched_videos[j].name) == 0)
                count += viewers[i]->watched_videos[j].unique_views;
        }
    }
    if(count > 0)
        return count;
    return -1;
}


int main()
{
    Video videos[] = { {"Soccer", 500},
    {"Basketball",1000} };
    Viewer viewer = {"Dave",videos,
        2};

    Viewer *viewers[] = { &viewer };
    printf("%d", count_views(viewers, 1, "Soccer")); /* should print 1 */
}
