This is a nice function posted by Cactus Hugger, a while ago. It removes blank spaces from a string. I'll bet you could easily figure out how to alter this function to remove any ascii value you sent to the function as another parameter:

Code:

void remove_spaces(char *string)
{
	char *read, *write;

	for(read = write = string; *read != '\0'; ++read)
	{
		/* edit: or if(!isspace(*read)), see swoopy's suggestion below */
		if(*read != ' ')
		{
			*(write++) = *read;
		}
	}
	*write = '\0';
}

If you get stuck, fear not - there are all kinds of ways of doing this function. Post up your problem when and if your function has errors you need help with.

If you're trying to remove the newline that is usually present in strings read by fgets(), there are many ways to do it. The favourite seems to be this:

Code:

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

char line[BUFSIZ], *p;
fgets(line, sizeof(line), stdin);
if((p = strchr(line, '\n'))) *p = 0;

Do a board search and you'll find many other ways. Here's another related thread: how to remove newline from a string

Warning.....

Code:

char *szString = "Some type of string.\n";

Do not try to alter the above string. If you want szString to be altered, it should be declared like this:

Code:

char szString[] = "Some type of string.\n";

Internally, the two forms are very different. One major difference is that the string could very well be in read-only memory, which can cause severe problems for you later on.

that's why the first string should be declared as const char* in the first place
