how do i go about converting a std::string to an int or float?

as well is there an equiviant to sprintf for the c++ std::string object?

any other information on std::string would be very helpful as well.

i havent used it very much & could use as much info as possible

thanks

well. i made one small change. i dont think it was significant enough to cut over 9 seconds off though, but i guess it was. it now runs in 1.709 seconds

heres my new code:

[cpp]/*
*
* Solves #440 - Eeny Meeny Moo
*
*/

#include <iostream>

using namespace std;

void main(void) {

int *cityOnNet ...

the problem is youre reading from files

when submitting to this judge, input comes from stdio

so in c++ the way i do it is

[cpp]#include <iostream>

using namespace std;

while(cin >> someVariable){

yourProblemSolvingCodeHere

}[/cpp]

im also sending this in through the online submission page

any chance that could have anything to do with it?

most likely not i guess?

i compiled using input from files

it took about 12 seconds to do all 147 valid inputs

why cant it do 5 in 10 seconds for the judge?

might the following have something to do with it

or should i say lack of the follow:

[cpp]
using namespace std;
[/cpp]

?

but compiling and running my code on my pc, it runs extremely fast. evidently < 1 sec for all valid input 3<=n<=150. i do not understand why when it gets to input 5, at about 5 secs, it takes more than 5sec to solve it. There must be another problem?

thanks

that now makes it terminate on my end

but when i submitted again, it still execeeds time

it gets stuck on input 5 it seems

actually i decided to post my code anyway. it executes really quick when i use it.

[cpp]
/*
*
* Solves #440 - Eeny Meeny Moo
*
*/

#include <iostream.h>

void main(void) {

int *cityOnNet, *cityOffNet;
int citiesOff, citiesOn, nextCity, numCities, m;

while(cin >> numCities != 0) {
cityOnNet ...

My 440 works, i tested with all sample input, but it goes over the 10 seconds.

When i compile and run & i hit 0, the program wont terminate, but it wont let me type

If you wish to see my code, i will post it

not sure as of right now but...

did u try all possible cases to ensure the output is correct?

cout << "Integers must be between 0 and 10000.\n";

neither is that, but that else condition should never be satisfied anyway.

also might wanna throw a @begin_of_source in there to be safe

i get an error when trying to include <string>. it doesnt exist

and bool doesnt work.

mebbe someone with borland will enlighten me

ive tried bool in lowercase & i dont thing my compiler has that string object.

mebbe time for new compiler

how do u reallocate memory & how do i use the string object?

also i tried declaring a BOOL variable but got an error.
