C++ :: Creating Timer - Count By Milliseconds And Return A True Value

Jun 19, 2013

I'm looking to create some sort of a timer. I'd like it to count by milliseconds and return a true value when it counts to a specific time. It would be used something like this:

if(alarm(1000)) {
// do some code
}

I tried using time.h, but it doesn't seem to have any millisecond commands. I need something faster than a second.

C++ :: Function Return Is Always True?

Oct 2, 2013

This program that I've made works fine to find midpoint, but not distance. The distancefunction always returns a 1 (true). To try to see that it wasn't the math, I added cout.setf(cout.boolalpha) to see and got a result of "true".

//This program is a start to solve basic coordinatre plane distances and midpoints
#include <iostream>
#include <cstdio>
#include <cstdlib>
using namespace std;

C++ :: How To Create Count Down Timer For 1 Hour 30 Minutes

Apr 7, 2014

I want to add a count down timer to my testing software 1hr and 30min

Its a 32bit console application, I want the countdown timer outputted above each question on the right side, timer only needs to output the time left at the top of each question so a live outputted timer is not important.

Questions are not random generated.

Also how to output "out of time" if the timer reaches 0 and for the test to end, I think branching is involved not too sure.

I already have, std::srand( std::time(0) ) ; at the start of the test to randomly generate the answer order.

C :: Return Number Of Bits Set To True

Jan 3, 2015

The task is to return the number of bits set to true.Here is my code:

Code:

int cardinalityBS(PBitSet _this) {
int s, counter = 0;
for(s = 0; s < 31; s++) {
counter += _this->bits & 1;
_this->bits <<= 1;
}
return counter;
}

[code]....

The code is not working, since whenever I set _this->bits to a number, it returns me the wrong result.

C++ :: Timer With Non-return Calculations

Dec 25, 2013

My game runs in a while loop, as you can see in the code below. I need a timer, which won't stop this loop or freeze it, but it will wait, until timer is over and executes code without interfering with the while or for loop.

Code:

Code:
#include <iostream>
#include <iomanip>
#include <windows.h>
#include <ctime>
using namespace std;
char *map[25][25];

C++ :: Binary Search Function - Return True If Element Inputted By User Found In Array And False If Not

Nov 9, 2014

I was instructed to write a binary search function which would return true if an element, inputted by the user, was found in the array, and false if it was not. I'm not sure why, but my function always returns false. My code is as follows.

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
//binary search function
bool search (int array[], int item)

[Code] ....

Why my code does not fulfill it's purpose???

C++ :: Creating Flexible Interface For CL Application - Auto Return Type?

Nov 24, 2013

I am trying to create a flexible interface for my CL application. And what i have is this :

Code:
using namespace std;
// iplcp -i queryFile -d databaseFile
template <typename INT, typename CHARA>
class API {

vector<string> files;
vector<INT> flags;

[Code] ....

and in main :

int main(int argc, char **argv){
//set variables
API<int, char**>args(argc,argv);
cout << "In file: "<< args.GetOpt("i") << " Db file: " << args.GetOpt("h") << endl;
}

// first thing to be printed should be string and the second int

I know this is not probably the best way to but i am laying around and was curious if something like this could work . Are there any good C++ templates for CLI applications from which i could learn?

C++ :: Creating A Loop To Allow User To Choose To Return To Beginning Of Program Or Quit

Apr 6, 2014

I am currently having problems creating a loop that will allow my user to choose to return to the beginning of the program or quit.

#include <iostream>
using namespace std;
int main() {
int j;
do {float a;
cout << "+----Welcome to Basic Operations----+
| Select Your Operation |

[Code] .....

I have not yet finished designing the interface for a couple of the operations, but right now i am hung up on trying to return to the beginning. I believe it is because the j was defined inside do and isn't carried out of the do statement for while.

Visual C++ :: Program That Count From 1 To 12 And Print Count And Its Square For Each Count

Dec 16, 2014

4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.

4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.

4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

C++ :: How To Get Uniform Increment Of Milliseconds - System Time

I am a bit lost as I am new to C++ and programming in general.

#include <stdlib.h>

using namespace std;
int main() {
ofstream myfile;

1249
1250
1251
285216ms delay
2853
2854
2855
2856

in the csv file, as above, after every 12 to 13 increment of i there is a skip of 15ms to 16ms. I do not understand why the ms is not a uniform increment. Is there another way I can get a uniform increment of ms?

C :: Calculate Prime Numbers In Range And Return Count Of Prime Numbers

I wrote a program which sends a starting and ending range to other processes and the processes calculate the prime numbers in that range and return the count of prime numbers to the head process, process 0. But this is not working properly at the moment. I realize I still have to split up the range based on how many processes I have...I still have not figured out how I want to set that up. I

C++ :: If Function Is Executed Without Its Condition Is True

Mar 5, 2013

I am trying to write a simple program that produces different outputs based on entered age of two different users. Program should tell who is older and behave different if both users are older than 100.

Here is my program: Code: #include <iostream>

Why program executes this when both users are obviously more than 100

C/C++ :: Inputting True For A Boolean Variable?

Feb 7, 2014

My assignment : "Input the answer as the words true or false and put the user's answer in a boolean alphabetic variable."

My code:

bool T;
cout << "Type 'true' for lowercase or 'false' for uppercase";
cin >> T;
if (T == "true") {
cout << "Enter a whole number in decimal base: ";
cin >> dec;
cout.setf(ios::showbase);
cout << "Decimal " << dec << " to Hexadecimal with lowercase: " << setbase(16) << dec;
}

I'm not sure how to get 'true' as user-input as true for bool.

C/C++ :: Taking True Bool And Having It Display Statement Instead Of 1 Or 0

Dec 4, 2014

I am again a bit confused with bool since we have not used them much. I understand it is suppose to return a true or false value that is represented by 0 and 1. so I have these two bool's

bool Triangle::isRight() {
if (pow(largestSide(), 2) == (pow(smallestSide(), 2) + (pow(middleSide(), 2)))) {
return true;
} else {
return false;

[Code] ....

and then I cout to display them

cout << "Is this a right triangle: " << t2.isRight() << endl;
cout << "is this a Triangle: " << t2.isTriangle() << endl;

and i get this
"Is this a right triangle: " 0
"Is this a triangle: " 1

Which i know is correct but I want to replace the 1 and 0 with my own string but the things iv tried tweaking with has not worked.

Also in the file attached has some requirements from my teacher but i was confused at the second last one, --- bool isEqual(Triangle &other) and it says return true if triangles are equal and false if triangles are not.

I dont know if this is just simply if one triangle equals another (however you determine that) or if its for the two bool's, isTriangle() and isRight() or what.

C++ :: How To Switch Between Boolean True / False Logic Within Do / While Loop

Mar 25, 2014

I have a hit a snag in a number guessing game program. I was given a half-completed program and told to use functions to complete the missing pieces. It looks unwieldy, but this is how it is supposed to be. I have temporarily made the random guess value visible for troubleshooting purposes.

#include <iostream>
#include <time.h>
#include <stdlib.h>
using namespace std;
int welcome() {
cout << " Welcome to the hi-low game!" << endl;

[code]....

The issue lies within this piece of code:

checkGuess(guess, correct); done = false; //either true or false
} while (!done);
cout << "Congratulations, you got it!" << endl;
return 0;
}

I need to manipulate the Boolean variable done so that it registers as false when the user inputs a number higher or lower than the randomly selected value. However, if the user guesses correctly, done will become true and the program will end.

As it stands now, the program will not terminate, and if I set done equal to true like so:

checkGuess(guess, correct); done = true; //either true or false
} while (!done);
cout << "Congratulations, you got it!" << endl;
return 0;
}

Every number the user inputs will register as correct instead of the one right guess.

C/C++ :: Programs Keeps Producing True - No Matter If Two Numbers Are Equal Or Not

Sep 25, 2014

In my program I am supposed to call isEqualTo with a user defined class type, and print out if my two numbers being compared are equal or not. I had to write two versions of this, one with just a template which works fine, but when I implemented the class, all the sudden my program just spews out true no matter if actually equal or not. Here is what I have so far:

#include "stdafx.h"
#include <iostream>
#include "UserClass.h"
using namespace std;

template<typename T>
bool isEqualTo(T value1, T value2){
if (value1 == value2)

C Sharp :: Programmatically Expand Url Link To Its True Location?

Nov 28, 2012

How do you programmatically expand a url link to its true location?

Do you know about tinyurl.com and baidu.com? Baidu.com is a search engine that tries to discourage people from using their web site to make metasearch engines by hiding their links in a way that is a lot like how tinyurl.com works. TinyUrl.com is a web site where, if you want to present someone with a link to something and that link is long, you can use tinyurl to produce a tiny url for presentation purposes.

Anyway, what I want to do is to find a way to programmatically take the link [URL] (the first link in a search for Jessica Alba using baidu.com) and have it return the actual link, [URL] . That is just one example. What I want to do is not specific to Jessica but for using Baidu.com as part of my group of search engines in my meta search eneing project.

Maybe there is a way of using the WebBrowser class but I did not see a member that was the URL.

Maybe there is a way of using WebRequest and WebResponse.

Visual C++ :: Program Doesn't Accept Input Values True?

Nov 1, 2014

I am making a program which is going to print out a head image according to the input values entered by the user. Here is the code:

Code:
#include <iostream>
#include <string>
using namespace std;
void Sides()
// draws the sides to take proportion

[Code] .....

At first i tried to work program like:

Code:
cout << "plase enter which way you want to print out the head, with parted hair or bald." << endl;
cin >> headstyle;
if (headstyle != "bald" || headstyle != "parted hair" )

But it also had given the same mistake. The program compiles BUT; even if I put in the values bald or parted hair the program prints out "wrong input" then exits.
