我的程序需要两个命令行输入，stock.csv并且coins.csv. 在我的程序开始附近，我load_check = load_data(&tm, argv[1], argv[2]);将文件初始化为链表。问题是，不知何故，这行代码正在改变argv[1]to的值d，但argv[2]仍然是coins.csv。我真的很困惑是什么原因造成的，这真的很奇怪。有任何想法吗？
编辑：抱歉响应缓慢，发现代码的另一个问题并正在修复它。代码load_data（现在将argv[1] 更改为""）
BOOLEAN load_data(tm_type * tm, char * stockfile, char * coinsfile)
{
stock_node *sstream = NULL;
char* token;
char line_no[LINE_LENGTH + 1], *ptr;
FILE *sfile, *cfile;
BOOLEAN check = TRUE;
int denom = 0;
if((sfile = fopen(stockfile, "r")) == NULL){
fprintf(stderr, "Error in %s.\n", stockfile);
check = FALSE;
}
if((cfile = fopen(coinsfile, "r")) == NULL){
fprintf(stderr, "Error in %s.\n", coinsfile);
check = FALSE;
}
sstream = tm -> stock -> head_stock;
while(fgets(line_no, LINE_LENGTH + 1, sfile) != NULL){
sstream = malloc(sizeof(tm -> stock));
sstream -> data = malloc(sizeof(struct stock_data));
token = strtok(line_no, ",");
strcpy(sstream -> data -> ticket_name, token);
token = strtok(NULL, ",");
sstream -> data -> ticket_type = token[0];
token = strtok(NULL, ",");
strcpy(sstream -> data -> ticket_zone, token);
token = strtok(NULL, ",");
sstream -> data -> ticket_price = strtol(token, &ptr, 10);
token = strtok(NULL, ",");
sstream -> data -> stock_level = strtol(token, &ptr, 10);
sstream -> next_node = tm -> stock -> head_stock;
tm -> stock -> head_stock = sstream;
}
while(fgets(line_no, LINE_LENGTH + 1, cfile) != NULL){
token = strtok(line_no, ",");
tm -> coins[denom].denomination = strtol(token, &ptr, 01);
token = strtok(NULL, ",");
tm -> coins[denom].count = strtol(token, &ptr, 10);
denom++;
}
return check;
}
变量变化发生在第五次迭代中
while(fgets(line_no, LINE_LENGTH + 1, cfile) != NULL){
token = strtok(line_no, ",");
tm -> coins[denom].denomination = strtol(token, &ptr, 01);
token = strtok(NULL, ",");
tm -> coins[denom].count = strtol(token, &ptr, 10);
denom++;
}
另外，tm -> coins[denom].denomination = strtol(token, &ptr, 01);给我一个warning: Invalid parameter passed to C runtime function.错误，但似乎并没有以任何其他方式影响代码。
