    if(n>=1 && n<=12)

    }else
    {
        s = month[12];
    }
    return s;
}

6-3 计算最长的字符串长度

代码

int max_len( char *s[], int n ){
    int i,count=0,j,q[20]={0};
    for(i=0;i<n;i++){
        for(j=0;*(*(s+i)+j)!='\0';j++){
        }
        q[i]=j;
    }
    count=q[0];
    for(i=0;i<n;i++){
        if(q[i]>count){
            count=q[i];
        }
    }
    return count;
}
