Thread: croping strings

Here's a possible solution:

Code:

#include <stdio.h>

void CropString(char *p, int amt);

int main()
{
	char str[] = "123456789";

	CropString(str, 3);
	
	printf( "str: %s\n", str );
	
	return 0;
}

void CropString(char *p, int amt)
{
	char *t;

	t = p;		// used to walk through the string

	while (*t)	// while we are not at the end of the string
	{
		if (amt)	// skip over characters
		{
			amt--;
			t++;
		}
		else		// start copying characters
		{
			*p = *t;
			p++;
			t++;
		}
	}

	*p = '\0';		// finally, add the null
}

Well if you want to save some copying, do this

Code:

str[]="abcdefg" 
char *clipped_str = &str[3];
printf( "%s\n", clipped_str );
