Re: how can i delete file after reading from any directory

29-Aug-07 1:36

there is certainly technique to delete a non system file, which i used some years ago. i can recall and reply you soon.
but temporarily, i can suggest you to simply create the file and close the file such that the data will be lost.
will it be sufficient for you?

Using MFC,have a look at CFile::Remove()

There's always the DeleteFile() API.

How can I convert dec to bin?

int i=123;
printf("dec: %i bin: ???", i, i);

try to answer my question, i have put it under your first post.

Is it some kind of assignment to you? Anyways here is the code :

int ConvertDecimalToBinary(int i)
{
	int temp = 0 ; 
	int counter = 1; 
	int binary = 0 ; 
	while (0 != i)  
	{
		temp = i%2;
		i = i/2;
		binary += temp*counter;
		counter*=10; 
	}
	return binary;
}

printf("dec: %i bin: ???", i, i);

and yes, printf("dec: %d bin: %d", i, ConvertDecimalToBinary(i));

and this function does have its limitations.

dear AnShUmAn
can your code get me answer for the integer 100?
please verify and reply Confused | :confused:

_AnsHUMAN_ 29-Aug-07 1:50

29-Aug-07 1:50

do you doubt it? why so
Then check it for urself.
I didn't try executing it and still it should work fine for all numbers that are within the int range whether it be 2 or 100.

does it work for 1024?

_AnsHUMAN_ 29-Aug-07 2:04

29-Aug-07 2:04

it won't work for that number because the value being returned is an int and range for int's is upto 32767 and while performing the calculations the number (value "binary" being returned from that function) exceeds the limits. ie why I said that this technique is quick and dirty Smile | :)

. OPTIMIZE it

void DecimalToBinary(int number) {
int value;

if(number <= 1) {
cout << number;
return;
}

value = number%2;
DecimalToBinary(number >> 1);
cout << value;
}
Now it would............ and now don't say that it won't work for a negative number :->
Just do some error handling. I hope that this does work for you Blush | :O

It's a good thing, too. Otherwise you would have quickly realized your function does not "convert" its argument to base-2. The function will need to return some sort of char* or string in order to properly represent a base-2 number.
