存储字符串的某些部分

Question

对于下面的代码，我的输入如下：

score Bob 10
score Jill 20
score Han 20
highscore
best Bob

代码：

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


typedef struct score_entry
{
    char name[21];
    int score;
} score_entry;


int main(void) {
    int i;
    char s[100];
    score_entry readin[30];

    while (1 == scanf("%s",(char*)s))
    {
        if (strncmp(s,"score",5)){
            //how to store string an name ?
            i++;
        }
    }
    return 0;
}  

s语句后面的字符串if是“nameint”...我想将名称存储到readin[i].name，将int存储到readin[i].score ......我怎么能这样做？

修改

这有效：

typedef struct score_entry
{
    char name[21];
    int score;
} score_entry;

int main()
{

    int i, j;
    int input_tokens;
    int score;
    int highest_score;
    int highest_individual_score;
    char input[100];
    char name[21];
    char scoretoken[10];
    score_entry readin[30] = {{0}};

    i = 0;

    while(i < 30 && fgets(input, 100, stdin) != NULL)
    {
        input_tokens = sscanf(input, "%9s %20s %d", scoretoken, name, &score);
        if (input_tokens == 3)
        {
            if (strncmp(scoretoken, "score", 5) == 0)
            {
                strncpy(readin[i].name, name, 20);
                readin[i].score = score;
                i++;
            }
        }
        else if (input_tokens == 2)
        {
            if (strncmp(scoretoken, "best", 4) == 0)
            {
                highest_individual_score = 0;
                for (j = 0; j < 30; j++)
                {
                    if (strncmp(readin[j].name, name, 20) == 0 && readin[j].score > highest_individual_score)
                    {
                        highest_individual_score = readin[j].score;
                    }
                }
                printf("Highest score for %s: %d\n", name, highest_individual_score);
            }
        }
        else if (input_tokens == 1)
        {
            if (strncmp(scoretoken, "highscore", 9) == 0)
            {
                highest_score = 0;
                for (j = 0; j < 30; j++)
                {
                    if (readin[j].score > highest_score)
                    {
                        highest_score = readin[j].score;
                    }
                }
                printf("Highest score: %d\n", highest_score);
            }
        }
    }

    return 0;
}

Answer 2

假设你想为此使用scanf，那么你可能想要：

int i, num;
char szScore[10];
i=0;
while( scanf( "%s, %s,%d", szScore, s, &num) )
{
  if( !strncmp(szScore, "score", 5)
  {
    strcpy( readin[i].name, s);
    readin[i].score = num;
    i++;
  }
}
