从一个文件拷贝数据到另外一个文件
各位大神们,我调试这个程序三天了,结果还没搞定,急死我了
总是不能正常的把数据从文件里面读取出来,还请各位帮帮忙,看一下
谢过了
int main(void)
{
int max=0;
int temp_max=0;
//only equle 0,1
int compare_result=0;
int loop_compare=0;
int loop_read_search=0;
int leng_of_geweishu_file=204552;
int leng_of_serach_file=210;
char *path_geweishu="result.txt";
char *path_search="search_data.txt";
//int geweishu[leng_of_geweishu_file];
char *search_number=(char *)malloc(sizeof(char)*9);
FILE *search_file;
FILE *result_file;
int *test_number = 56;
printf("Test number is: %d", test_number);
printf("start open file \n");
search_file = fopen(path_search, "r");
result_file = fopen(path_geweishu, "w+");
int temp_result[210];
if((search_file && result_file) == NULL)
{
printf("Can't open file\n");
}
printf("start LOOP to read file \n");
for(loop_read_search=0;loop_read_search<leng_of_serach_file;loop_read_search++)
{
//read_file_search(search_number,search_file);
printf("aready in the loop! \n");
fseek(search_file,(sizeof(int)*4+2),0);
fgets(search_number,16 ,search_file);
//fscanf(search_file,"%d",search_number);
//fscanf(search_file,"%4d",search_number);
temp_result[loop_read_search]=(*search_number);
printf("%d,\n", (*search_number));
fprintf(result_file,"%d \n", temp_result[loop_read_search]);
}
printf("start close file \n");
fclose(search_file);
fclose(result_file);
free(search_number);
}
int temp_result[210];
//if((search_file && result_file) == NULL){
// printf("Can't open file\n");
//}
printf("start LOOP to read file \n");
for(loop_read_search=0;loop_read_search<leng_of_serach_file;loop_read_search++)
{
//read_file_search(search_number,search_file);
printf("aready in the loop! \n");
//fseek(search_file,(sizeof(int)*4+2),0);
fgets(search_number,16 ,search_file);

//temp_result[loop_read_search]=(*search_number);
//printf("%d,\n", (*search_number));
//fprintf(result_file,"%d \n", temp_result[loop_read_search]);
fprintf(result_file,"%s", search_number);
}
printf("start close file \n");
fclose(search_file);
fclose(result_file);
free(search_number);
return 0;
}
运行结果
