Thread: processing a char pointer/string

Hello..
Im making a code for processing a data that contains \r\n or just \n at the end of each line. Heres what I have written so far:

Code:

char *tmp, *temp, *ptr;
tmp = new char[1024];
sprintf(tmp, "line 1\r\nline 2\r\nline 3\n");
printf(tmp);

temp = tmp;
while (1) {
	ptr = temp;
	temp = strchr(ptr, '\n');
	
	if (temp)
		*(temp++) = 0;
	else
		break;

//something missing

	printf("line: %s\n", ptr);
}

this will print:

line 1\r
line 2\r
line 3


Now the problem is I dont know how to check if the last character/letter in the line is \r set it the *pointer to 0.

What would be the best way to do this?

Thanks a lot for help
