getline problem

[elwad]

hey guys i m srry for asking to much but here i know the problem
x will be alawys = to longest i m trying to make a program to get longest line and if user wanna quit and see the longest line he did it will post it but i dunno like whats best choice so where longest will maintain its length and not follow x thanks

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int getline_program(char *buffer,int num)
{
	fgets(buffer,num,stdin);
	return strlen(buffer)-1;
}
void save_it(char *buffer,char *buffer1)
{
	int i,x;
	for(i=0,x=0 ; buffer[i]=buffer1[x] ; i++ ,x++);
}
int main(void)
{
	char name[100];
	char *buffer;
	int x,longest,swap;
	buffer=malloc(sizeof (char)*100);
	for(;;){
		x=getline_program(name,sizeof name);
		save_it(buffer,name);
		longest=x;
		swap=longest;
		printf("x=%d\t longest=%d\n %d\n",x,longest,swap);
		if(x>longest)
		{
			puts("its longer: preforming functions\n");
			free(buffer);
			buffer=malloc(sizeof (char)*100);
			longest=x;
			save_it(buffer,name);
			printf("Your longest name is %s and length is %d",buffer,longest);
		}
	}
	free(buffer);
	return 0;
}

char longestline[ BUFSIZ ] = {0};
size_t longestlinelength = 0;

Start with that.

while they don't feel like quitting
    Read a line.
    Get its length.
    Compare that length to the longestlinelength.
        store the longest line

Personally, I'd get it working with an array first, rather than allocating memory. Throw that in later if you really want to get a handle on dynamic memory allocation.

thanks man i got it working now i was just using dynamic memory to get the hang of it and see how it works etc
