Removing char from string

[cruxxe]

/scan word from file/

do
{
wordscan = fscanf(f, "%s", buffer);
if (wordscan != EOF)
{
if(strstr(buffer, filter))
{
temp = buffer;
charstart = strlen(strstr(temp, "file:/") - 1);
charend = strlen(temp);
printf("%s, %d\n", temp, charend);
}
}
} while (wordscan != EOF);
printf("File: %s is processed. \n", argv[i]);

/end code/

Hi, need some help regarding some issues in the above codes. I have managed to extract word from the file but I need only specific text from a long string eg href:/abc and I need only abc. I know the position of a as well as c.....I have tried using for loops to retrieve abc but it did not seems to work. What could possibly be wrong??

And is the code above looks alrite??

Thanks

Study this one, it may help you

#include <stdio.h>
#include <string.h>

int main(void)
{
	char	data[] = "href:/abc";
	char	*ptr;

	printf("The full string is %s\n", data);

	if ((ptr = strchr(data, '/')) != NULL)
	{
		ptr++;
		printf("The second part is %s\n", ptr);
	}

	return(0);
}

Please use code tags in future, too.

Thanks Hammer...

Hammer's solution is really just a work around. It doesn't actually remove anything from the string.

To actually remove an item, you need to do the following:

while not what I'm looking for
{
    skip ahead to the next character
}

do
{
    copy the next character to the current location
    move to the next location
}
while not the end of the string

Given the above pseudo code, you shouldn't have any problems getting the task done.

That depends on how you read the requirement

My solution got a pointer to.... well, you can see what it does.

Admittedly the title of this post is "Removing char from string", but as cruxxe gave a specific example, that's the one I chose to address.

Very true. I just went by the title of the thread. This is one of those 'I want this, no I mean this.'
