c++ - C编程: Running 2 while loops and get the random result for data from loop1

Question

我使用 2 个 while 循环从 2 个文件读取数据并存储在 2 个不同的数组中。问题是当我想打印第一个数组中的数据或在第二个 while 循环之后打印第一个 while 循环中的数据时，我得到的随机结果与文件中出现的不同。

#include <stdio.h>

int main(){
    FILE *fp, *fp2;

    fp = fopen("example1.txt", "r");
    fp2 = fopen("example2.txt", "r");
    float breaks_buffer[255], yr_buffer[1000], res1[200];
    float new_data_breaks[200], new_data_yr[200];
    int i, new_index_breaks, j, new_index_yr, a;

    /*=========== GET DATA FROM FILES INTO ARRAYS  ==========*/

    /*=== DATA_BREAKS INTO ARRAY:  "new_data_breaks" ===*/
    i=0;
    new_index_breaks =0;
    while(!feof(fp)){
        fscanf(fp, "%f", &breaks_buffer[i]);
        new_data_breaks[new_index_breaks] = breaks_buffer[i];
        i++;
        new_index_breaks++;
    }
    /*=== DATA_YR INTO ARRAY:  "new_data_yr" ===*/
    j=0;
    new_index_yr =0;
    while(!feof(fp2)){
        fscanf(fp2, "%f", &yr_buffer[j]);
        new_data_yr[new_index_yr] = yr_buffer[j];
        j++;
        new_index_yr++;
    }

    /*=== TEST PRINT DATA ===*/
    for(a=0; a<new_index_breaks;a++){
        printf("%f\n",new_data_breaks[a]);
    }
    fclose(fp);
    fclose(fp2);
    return 0;
}

尝试一下while(fscanf(~~~) != EOF) {...}

缓冲区数组真的需要吗？我宁愿不使用这些在我的情况下。祝你好运。
