c - 读取数据文件时出现段错误

Question

我正在尝试将字 rune 件读入 64 个字符的数组。文件读取发生在 main()

中

int main (int argc, char **argv)
{
    FILE *fp;
    char write_msg[BUFFER_SIZE];

    fp = fopen("test.data", "r");

    int i;
    for ( i = 0; i < (BUFFER_SIZE-1); i++){
      fscanf(fp, "%s\n", &write_msg[i]);
      printf ("printing in the for loop");
    }
    fclose(fp);
    printf("Starting the main().\n");
    printf("in Reader, the msg is: %s\n",write_msg);

    pid_t pid;
    int fd[2];

我一直遇到段错误，我不确定自己在做什么

Answer 1

fscanf(fp, "%s\n", &write_msg[i]); 应该是 fscanf(fp, "%c\n", &write_msg[i]);，您不想将字符串扫描成字符。

并且 write_msg 应该以 '\0' 结尾，write_msg[BUFFER_SIZE-1]=0
