Question

我必须逐行将文件中的数据读入结构数组，但它会跳过第一行。我发现其他地方，因为fgets和sscanf组合第二行是第一次阅读，但我不明白为什么或如何我可以解决这个问题。任何建议或指向正确的方向都会很棒！

void readData(){
    char line[50];
    char name1[1][50];
    int O, M, R, W;

    input = fopen("input2.dat", "r");

    //count = 0;
    while(fgets(line, 50, input) != NULL){
        hasReadData = 1;
        sscanf_s(line, "%20s %d %d %d %d", name1[0], 50, &O, &M, &R, &W);

        for(i=0; i<200; i++){
            if(strcmp(name1[0], player_arr[i].name) == 0){
                if(O<0 || M<0 || R<0 || W<0){
                    printf_s("%s %d %d %d %d", name1[0], O, M, R, W);
                    printf_s("\tNegative value, data invalid\n");                   
                    break;
                }
                if(O<M){
                    printf_s("%s %d %d %d %d", name1[0], O, M, R, W);
                    printf_s("\tOvers less than Maidens, data invalid\n");
                    break;
                }
                if(W>10){
                    printf_s("%s %d %d %d %d", name1[0], O, M, R, W);
                    printf_s("\tWickets greater than 10, data invalid\n");                  
                    break;
                }

                player_arr[i].oversOverall += O;
                player_arr[i].maidensOverall += M;
                player_arr[i].runsOverall += R;
                player_arr[i].wicketsOverall += W;

                player_arr[i].oversLatest = O;
                player_arr[i].maidensLatest = M;
                player_arr[i].runsLatest = R;
                player_arr[i].wicketsLatest = W;
            }           
        }
    }
    fclose(input);
}

如果你在读取文件的同时跳过第一行，那么在while循环中使用这个命令：

file_pointer.seekg(0,ios::beg);

此文件指针将指针指向文件的开头。

while循环从文件中读取跳过第一行
