尝试读取二进制文件并查找用户输入的字符串

Question

您好我正在尝试创建一个函数，它将以字符串搜索形式从用户那里获取包含足球结果的二进制文件，例如（Chelsea，Liverpool，1,2），并在每次出现字符串时打印例如，如果用户进入利物浦，则所有利物浦的结果将被打印到屏幕上。我的代码不会打印任何内容。我究竟做错了什么？这就是我所拥有的。

struct matches 
{
    //structure members
    char teamA [100]; 
    char teamB [100];
    int goalsA;
    int goalsB;
};    
void displayMatches()
    {   
        struct matches match; //declare variable of type struct

        char input[20]; //variable to take input from user 

        FILE * file1; //pointer to a file

        file1 = fopen("matches.bin","rb");//open binary file in read mode 

        if(file1==NULL) //error check for file
        {
            printf("open file error.\n");
            exit(6);
        }

        printf("Enter the team\'s results you want to view\n");
        scanf("%s",input);

        /*loop to read binary file check if input team 
         is in file if yes print the results for that team */
        while(fread(&match,sizeof(match),1,file1)) 
        {



            if(strstr(match.teamA,input))
            {

                printf(" %s %s %i %i ",match.teamA,match.teamB,match.goalsA,match.goalsB);

            } 
            else if(strstr(match.teamB,input))
            {

                printf(" %s %s %i %i ",match.teamA,match.teamB,match.goalsA,match.goalsB);

            }

        }

        fclose(file1);
    }
