    last string is always the answer

    #include <stdio.h>
    #include <string>
    #include "simpio.h"
    #include "genlib.h"
    #include "strlib.h"
    int main() {
    	string longestString, current;
    	int work = 0;
    	int possible;
    	int greatest;
    	printf("please enter a list of strings, end the list with the word 'end'");
    	printf("enter: ");
    	current = GetLine();
    	longestString = current;
    	greatest = StringLength(current);
    	while(work == 0) {
    	printf("enter: ");
    	current = GetLine();
    		if (StringEqual(current, "end"))
    		else if (StringLength(current) > greatest)
    			greatest = possible; 
    			longestString = current;
    		else {
    	printf("the longest string is: %s\n", current);
    it should put out the longest string but it always says end is

    Because you are printing the current string? If you want to print the longest string, then you should print longestString instead.

    Inside my computer
    There is something that is seriously wrong with that code...
    I fail to see "using namespace std;" anywhere, and I still see printf instead of std::cout. Plus I see StringEqual (probably uses strcmp or something) and StringLength (probably uses strlen or something).
    If you are going to use C++, then you should stick to it and not C.

    And lastly, try writing a flowchart or pseudo-code sometime to see what you are actually doing.

    Outside of your DOS world, your header file is meaningless.
