问题描述

C 在做USACO Greedy Gift Givers的时候遇到bus error 10

下面是我的代码 (C语言)

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

FILE *input_file, *output_file;

int total_people, giving_to_counter, accepting, having[9];

char giver[9][13], receiver[9][13], person;

int people_scaner, people_judger;

int main () {
    input_file=fopen("gift1.in", "r");
    output_file=fopen("gift1.out", "w+");

    fscanf(input_file, "%dn", &total_people);

    people_scaner = 0;

    while(people_scaner<total_people){
        people_scaner ++;
    }

    fscanf(input_file, "%s", &person);
    printf("%sn", &person);

    people_judger = 0;

    do{
        people_judger ++;
    } while (strcmp(&person, giver[people_judger]) !=0);

    fscanf(input_file, "%d%d", &having[people_judger], &giving_to_counter);
    printf("%dn%sn%dn%dn", people_judger, giver[people_judger], having[people_judger], giving_to_counter);

    fclose(input_file);
    fclose(output_file);
    return 0;
}

下面是要读取的文件

非常感谢您的回答：）

解决方案

来自stackoverflow的答案，一开定义了 char person，这是错误的，应该定义成char person[13]

解决方案二：
