我目前正在进行一项任务,要求我审查argv和输入重定向的单词。
我的问题在我的输出中很明显,可以在下面找到。我有很多跟踪打印声明,可能会或可能不会帮助您指出我的问题。
我的意图是:
file.txt
file.txt
的内容复制到buffer[x][y]
,其中[x]
是一个字词串,[y]
是[x]
的字符。argv[]
参数与buffer[][]
进行比较。newstr[size2]
。对于argv[]
中找到的每个buffer[][]
争论,请将其替换为replace[9] = "CENSORED"
。newstr[0 to (size2-1)]
。这是我的代码:
// censored.c
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <ctype.h>
#define SIZE 128
int main ( int argc, char* argv[])
{
int i = 0;
int j = 0;
int k = 0;
char buffer[SIZE][SIZE];
char x;
int count = 0;
int size1 = sizeof(buffer);
int size2 = 0;
char replace[9] = "CENSORED";
int buffersize=0;
printf("tracing: size1: %d.\n", size1);
printf("tracing: argc: %d.\n", argc);
while((fscanf(stdin, "%c", &x)!=EOF))
{
if(isalpha(x))
{
buffer[i][j]=x;
printf("tracing: buffer[%d][%d]: %c\n", i,j, buffer[i][j]);
j++;
}
else if(isspace(x)) // if whitespace
{
j = 0;
i++;
buffer[i][j]=x;//this should be buffer[i][j]
printf("tracing: buffer[%d][%d]: %c\n", i,j, buffer[i][j]);
j = 0;
i++;
}
else if(ispunct(x)) // if x is a punctuation
{
j = 0;
i++;
buffer[i][j]=x;//this should be buffer[i][j]
printf("tracing: buffer[%d][%d]: %c\n", i,j, buffer[i][j]);
}
else if(iscntrl(x)) // if control key (\n, \r etc...)
{
j = 0;
i++;
buffer[i][j]=x;//this should be buffer[i][j]
printf("tracing: buffer[%d][%d]: %c", i,j, buffer[i][j]);
j = 0;
i++;
}
else if(isdigit(x))
{
buffer[i][j]=x;//this should be buffer[i][j]
printf("tracing: buffer[%d][%d]: %c\n", i,j, buffer[i][j]);
j++;
}
else
{
break;
}
}
size2 = i;
printf("tracing: buffer[8][0]:%s\n",buffer[8]);
char newstr[size2][SIZE];
i = 0;
j = 0;
// tracing:
printf("tracing: line 72\n");
printf("tracing: size2: %d.\n", size2);
while(i < size2) //print buffer[]
{
printf("%s", buffer[i]);
i++;
}
printf("tracing: line 80\n");
for(k=1; k < argc; k++)
{
printf("%s\n", argv[k]);
}
// end tracing
i = 0; //reinitialize i
j = 0; //reinitialize j
// creating newstr[SIZE] and censoring words
printf("tracing: line 89\n");
for(i = 0; i < size2; i++)
{
for(j=1; j < argc; j++)
{
if(strcmp(buffer[i], argv[j])==0)
{
strcpy(newstr[i], &replace[0]);
printf("tracing: replaced at [%d]\n", i);
break;
}
else
{
strcpy(newstr[i], buffer[i]);
printf("tracing: copied at [%d]\n", i);
}
}
}
i = 0; //reinitialize i
while(i < size2)
{
printf("%s", newstr[i]);
i++;
}
return 0;
}
假设我输入了名为file.txt
的重定向文件及其内容:
Said Hamlet to Ophelia,
I'll draw a sketch of thee,
What kind of pencil shall I use?
2B or not 2B?
我的意见是:
./censored Ophelia thee 2B < file.txt
这是我得到的奇怪输出:
Said Hamlet to CENSORED, Ill draw a sketch ???)ofoQ? ?"h?CENSORED,2oQ?
What? /oQ?kind? of 6oQ?pencil +oQ?shall ?"h?I-oQ? ???)use? ???2BoQ?
7oQoroQ Qnot 1oQ?CENSORED?4oQ?
感谢任何帮助,我知道我的代码很乱,这是我第一次学习学习C.
答案 0 :(得分:2)
我有好消息和坏消息,坏消息是:我发现了一些错误和错误。 好的一点是:所有这些对初学者来说都很常见!
第一个:buffer[]
中的字符串不以'\0'
终止,而newstr
是字符串指示符的结尾。这是导致问题的原因之一。
以下是其他的:
main()
为空。通常我们使用NULL指针结束数组,然后在读取数组时检查数组的每个字符串是否为非null,以便我们不会尝试使用未定义的内容。j = 0;
i++;
buffer[i][j]=x;//this should be buffer[i][j]
printf("tracing: buffer[%d][%d]: %c\n", i,j, buffer[i][j]);
j = 0;
i++;
中的代码。 public class EventsFragment extends android.support.v4.app.Fragment {
private StackView stackView;
private ArrayList<Stack_Items> list;
TypedArray eventLogo;
String eventName[],eventDesc[];
@Nullable
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
eventLogo = getResources().obtainTypedArray(R.array.event_stack_icon);
eventName = getResources().getStringArray(R.array.event_stack);
eventDesc = getResources().getStringArray(R.array.event_desc_stack);
View view = inflater.inflate(R.layout.events_layout, null);
stackView = (StackView) view.findViewById(R.id.stackView1);
list = new ArrayList<Stack_Items>();
//Adding items to the list
for (int i = 0; i < eventLogo.length(); i++) {
list.add(new Stack_Items(eventName[i], eventLogo.getResourceId(i, -1)));
}
//Calling adapter and setting it over stackView
Stack_Adapter adapter = new Stack_Adapter(getActivity().getApplicationContext(), list);
stackView.setAdapter(adapter);
stackView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> a, View
view, int position, long id) {
MainActivity mainActivity = (MainActivity) getActivity();
FragmentTransaction fragmentTransaction = mainActivity.getSupportFragmentManager().beginTransaction();
Fragment eventDescFragment = new DynamicEventsPage().newInstance(R.array.event_stack,R.array.event_desc_stack,eventLogo.getResourceId(position, -1));
fragmentTransaction.replace(R.id.containerView, eventDescFragment);
fragmentTransaction.commit();
}
});
adapter.notifyDataSetChanged();
return view;
}
}
我认为现在已经足够了,祝你好运,为我可怜的英语道歉。
