Thread: Problem with deleting completely blank lines

Hello all...sooo I managed to solve most of the program. This program is suppose to filter out all blank and tabs of the lines I type in, and completely delete all blank lines. However I am unsure of how to do this. It still seems like it is printing the blank line. It does however filter all spaces and tabs. I commented my code as necessary. Help much apprecated!

Code:

#include <stdio.h>
#define UNLIMITED 10000

void blanklessCopy(char to[], char from[]);
int getline(char line[]);

//prints lines without blanks or tabs
//delete lines that are completely blank
main(){
	int len; //current line length
	char line[UNLIMITED]; //current input line
	char newLine[UNLIMITED]; //the new line
	
	//while len is greater than 0
	//means there was a line
	while ((len = getline(line)) > 0){
		//copy the line to newLine
		blanklessCopy(newLine, line);
		//what to do here?
		//means it was a blank
		if(newLine[0] == '\0'){
			;
		}
		//otherwise just print the new
		//filtered line
		else{
			printf("%s", newLine);
		}
	}
}

//copy from into to: assume to is big enough
//removes all blanks and tabs
void blanklessCopy(char to[], char from[]){
	int i, i2;

	i = i2 = 0;
	while (from[i] != '\0'){
		if (from[i] == '\t' || from[i] == ' '){
			i++;
		}
		else {
			to[i2] = from[i];  
			++i;
			++i2;
		}
	}

	to[i2] = '\0';
}

//read a line into s, return length
int getline(char s[]){
	int c, i;

	for(i = 0; (c = getchar()) != EOF && c != '\n'; ++i)
		s[i] = c;
	if(c == '\n'){
		s[i] = c;
		++i;
	}
	s[i] = '\0';
	return i;
}

That is because I am following the K&R book, I haven't got to that section yet. I guess it would be best to learn how to code the given "shortcut" functions, before using them. That way I won't take them for granted. Anyways it worked! Thanks for the help!
