Thread: Printing Length of Input and the Limited Input

Hmm...alright I'll change it around and see what I get, with the MAXLINE - 1 in mind. Also
silverlight, I apologize if this sounds rude, but I am trying to follow the book and using the information that they have given me so far to solve this problem. I believe I should solve this problem with the basics before getting into more complicated stuff or by using shortcuts. I appreciate your help and still want your help to solve this problem but in a less advanced way...for now.

So..I tried it again...this time my code does not seem to be doing anything. I think I have the concept down. However my code is wrong....I think the

Code:

(c = getchar())

must be intefering with my getline function...can somebody help me please?

Code:

#include <stdio.h>
#define MAXLINE 10

int getLine(char line[], int maxline);
void copy(char to[], char from[]);

//prints longest input line
main(){
	int len; //current line length
	int max; //maximum length seen so far
	int possiblemax; //possible maximum length
	int realmax; //the real maximum length
	int c; //the char
    char line[MAXLINE]; //current input line
	char longest[MAXLINE]; //longest line saved here
	
    max = possiblemax = realmax = 0;

	while ((len = getline(line, MAXLINE)) > 0)
		//checks to see if array ends with a new line
		if (line[len - 1] != '\n'){

			//while c is not end of file
			while ((c = getchar()) != EOF){
				//if c is not equal to a new line
				if (c != '\n'){
					//while c is not a new line add one to possible max
					while(c != '\n'){
						     ++possiblemax;
							 }
				}

				//else if is equal to a new line
				else if (c == '\n'){
					//if possiblemax is greater than real max
					//set realmax to possiblemax
					//reset possible max
					if (possiblemax > realmax){
                                realmax = possiblemax;
                                possiblemax = 0;
                }

				//otherwise reset possiblemax
					else possiblemax = 0;
                }
            }
        }
                                            
		if (len > max){
			max = len;
			copy(longest, line);
		}

		if (max > 0){ //there was a line
			printf("length:&#37;d", realmax);
			putchar('\n');
			printf("%s", longest);
		}
		return 0;
}

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

	for(i = 0; i < lim-1 && (c = getchar()) != EOF && c != '\n'; ++i)
		s[i] = c;
	if(c == '\n'){
		s[i] = c;
		++i;
	}
	s[i] = '\0';
	return i;
}

//copy from into to: assume to is big enough
void copy(char to[], char from[]){
	int i;

	i = 0;
	while ((to[i] = from[i]) != '\0')
		++i;
}
