my problem lies within the outfile.open(fi lename)
because of the syntax of the open() function quotes are required around the filename therefore i need to add them, otherwise if i use open("filename" ) it takes filename literally and not the var filename.

easiest thing to do is to use the "setprecision(N )" command and have N be a global int const for the desired ammount of decimal places that way you can chage it easier later on when code gets really big and complex n confusingLeave a comment:

are you looking to get rid of the whitespace before the string or throughout?
for case one you could just add a cin >> fistword; then after the getline st = firstword + st1;
for the second case i'm not too sure....Leave a comment:

Variable Filenames
Hey there pretty new to C++ and i'm trying to create a file that will create a file based on user input
here is a little snipplet of my code:
getline(cin,/*string*/ filename,'\n');
filename= " \" " + filename +" \" ";
outfile.open(fi lename);
any help appriciated thx -
also you could use the getline cmd. be sure to use the cin.ignore(25, '\n') between the cin.
with your ifstream (i believe srry really tired here), lets say infile, use the getline with the tab delimiter to get the info, followed by a cin.ignore, then infile>> to get the int. getline only works for strings so be careful;
basic code
getline(infile, stringVARIABLEn ame, delimiter);
cin.ignore(intO FhowMANYcharsTO ignore,...Leave a comment:

i tried approaching this challenge a different way. first off i made this program write one line of the whole board x number times then made it rpt a couple of time (pardon the poor writing but its 5 in the morning and i'm dead tired (working) trying to get things to makes sense)
here is my program for creating the board. personally i would have used arrays and functions but this is taking off of what you had originally.

I couldn't help you with what the error stands for however if you submit your code i'm pretty sure that someone in this community would have an answer for you
plus it would make it easier for us to spot what your specifically doing worng and not just give you the reason(s) why that error is appearingLeave a comment:

returns the distance between the two points.
Write a function “distance” that takes four arguments
from these two parameters you know you have somthing like
returntype functionname(ar g1, arg2, arg3, arg4)
{
since your finding the distance use the pythagorean therom from the difference of two of the four arguments
return ans of formula
}
and i have no idea what you mean by...Leave a comment:

Primitive Passwords
Hey!
I got a really simple idea for creating and storing passwords i just don't know how to code it.
to realize my idea i need to create a txt file that will store passwords i'm just confused by the fstream commands.
how could i impliment reading a file to find a certain word?
for example lets say i create a password "Boog". and place it after pswd2: in a file ( pswd2: Boog).

Getting A Clock to Appear
Hey i have no idea if this is even possible without a GUI.
just for fun i'd like to create a timeclock program for win xp using C++ .NET. i though it'd b neat if i could see the time in the form of a clock in 24 hr on the screen. (11:25:59) hours:min:sec.
also is there a way for me to be able to throw in a switch with a case
"I" that would get the current time? (i.e. press i and double variable "in" gets... -
uhhhh stay away from recursive programming!!!! ! yea its easy but it eats up mem and cpu usage!!!!!
i.e.
go to a porn site (and turn your popup blocker off!!!).
this is what recursive programing does if each window was a recursive function call.
pretty much each time you call a function (lets say b) the calling function (lets say a) is put on hold.
therefor function a calls b and both are open until b closes/ends...Leave a comment:

like banfa said: your not static casting the right way. (you can't div int by int and then static cast but you have to div static cast by int of int by static cast.)
try this code:
#include <iostream>
#include "string.h"
using namespace std;
int main()
{
string candidate1 = "";
string candidate2 = "";

it might depend on the program/compiler as well
for the two
the way it would be 12 and not 6 would be because it incriments and decrements the prefix before it uses the value and not the statement; ie
a=2
x=++a*--a*a++
it would incriment a to 3 first
then a =3 and not 2!!!!
producing 3*2
then since we postfix a is changed after use
making the expression x=3*2*2=12...Leave a comment:

it should be 5 but since its the same variable consider:
x=++a*--a*a++;
since your incrimenting and decrimenting it becomes the original value
prstatement
a=6
first (++a)
a=7
secont pre(--a)
a=6
no more pre means do the statement
x=6*6*6
x=216
post fix (a++)
a = 7Leave a comment:
