C++ :: Print Each Percent Of Loop Breaks Down For Large Loops?
Feb 22, 2012
I'm trying to make a percentage counter inside a loop, printing each completed percent of the loop as it goes. I've managed to write such code, but when I run it the percentage output breaks down (becomes negative!) for large loops. I have an example below.
Code:
#include <iostream>
#include <sstream>
#include <string>
#include <stdlib.h>
#include <stdio.h>
using namespace std ;
int main() {
[code].....
Compiling and running the above yields the output:
Code:
...1% ...2% ...3% ...4% ...5% ...6% ...7% ...8% ...9% ...10% ...11% ...12% ...13% ...14% ...15% ...16% ...17% ...18% ...19% ...20% ...21% ...-21% ...-20% ...-19% ...-18% ...-17% ...-16% ...-15% ...-14% ...-13% ...-12% ...-11% ...-10% ...-9% ...-8% ...-7% ...-6% ...-5% ...-4% ...-3% ...-2% ...-1% ...0% ...1% ...2% ...3% ...4% ...5% ...6% ...7% ...8% ...9% ...10% ...11% ...12% ...13% ...14% ...15% ...16% ...17% ...18% ...19% ...20% ...21% ...-21% ...-20% ...-19% ...-18% ...-17% ...-16% ...-15% ...-14% ...-13% ...-12% ...-11% ...-10% ...-9% ...-8% ...-7% ...-6% ...-5% ...-4% ...-3% ...-2% ...-1% ...0% ...1% ...2% ...3% ...4% ...5% ...6% ...7% ...8% ...9% ...10% ...11% ...12% ...13% ...14%...100%
If I change the value of N to 1e7 instead of 1e8, the output is correct however!
Code:
...1% ...2% ...3% ...4% ...5% ...6% ...7% ...8% ...9% ...10% ...11% ...12% ...13% ...14% ...15% ...16% ...17% ...18% ...19% ...20% ...21% ...22% ...23% ...24% ...25% ...26% ...27% ...28% ...29% ...30% ...31% ...32% ...33% ...34% ...35% ...36% ...37% ...38% ...39% ...40% ...41% ...42% ...43% ...44% ...45% ...46% ...47% ...48% ...49% ...50% ...51% ...52% ...53% ...54% ...55% ...56% ...57% ...58% ...59% ...60% ...61% ...62% ...63% ...64% ...65% ...66% ...67% ...68% ...69% ...70% ...71% ...72% ...73% ...74% ...75% ...76% ...77% ...78% ...79% ...80% ...81% ...82% ...83% ...84% ...85% ...86% ...87% ...88% ...89% ...90% ...91% ...92% ...93% ...94% ...95% ...96% ...97% ...98% ...99%...100%

I'm programming an app that deals with large numbers. I have a do-while loop that I want to execute. I can not get it to work. The "while(d!=1)" part is the problem and I can not find a way around.
Code:
#include "stdafx.h"
#include <stdio.h>
#include <gmp.h>
#pragma comment(lib, "gmp.lib")
int main (int argc, char *argv[]) {
mpz_t d;
[Code] ....
I get errors:
1.error C2446: '!=' : no conversion from 'const int' to '__mpz_struct *'
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
2. '!=' : '__mpz_struct [1]' differs in levels of indirection from 'const int'

i have two loops ie.
if (n==null)
{
do loop 1
}
else //(n=!null)
{
do loop2
}
now i have to update the above code, with a single loop ie. when n==null or n!=null do the loop 1
how can i update.?
can i do like this
if(n==null ||n=!null)
{
do loop 1
}
is || operator above does the job what i expected

Consider:
Code: template<unsigned int N>
class Test
{
private:
[Code]....
I just cannot understand why (clearly, we are calling <0, 0>, not <0, 8>). If I replace "N" with 8, it works as expected (at least for the beginning of the loop). I only tested on MSVC.

I want to create a specific number of for loops each in another loop, as in example:
for(i=0;i<9;i++)
{
for(j=0;j<9;j++)
{
for(k=0;k<9;k++)
{
//some stuff
}
}
}
In this example there are 3 loops, but what if i want to create e.g. 10 such loops, and program reads a number of loops from a txt? It is needed for checking numbers.

I'm using an animation program. In this program I've simulated a particle system. The particles are flying around at different and varying speeds. I've attached birds to the particles and I want to be able to control each bird's flapping animation based on its velocity; so birds moving faster will be flapping faster.
Initially, the bird's flapping animation is controlled by a parameter that goes from 0 to 100%. So not only do I need to drive the speed at which the animation goes from 0 to 100%, I need to set it on a loop so once it reaches 100%, it loops back to 0%. I'm extremely new to code so I don't think it would be wise for me to even provide a jumping off point, not that I could.

Here is the code,
Code:
class A {
public:
virtual void foo(){}
};
class B : public A {
[Code] ....
Obviously when you call pA->foo, it will call foo defined in B. But foo defined in B is private. It is not supposed to be called outside the class B. So it looks like virtual breaks encapsulation.

I am working on a code and first i need to initialize the array depending on the size (min size 3x3, maximum size 9x9). The initialized array will descend in order. Note that it seems like a simple code and seems to work for any size from 3x3 to 7x7, but for some reason i get a strange output in the last few rows for 8x8 and 9x9. Not sure why. The second part to my problem is the very last digit of 0. I did hard code to define it but i would like to make it a character like an underscore...what is the easy way to do this?
* Implements the Game of Fifteen (generalized to d x d).
*
* Usage: ./fifteen d
*
* whereby the board's dimensions are to be d x d,
* where d must be in [MIN,MAX]
*
* Note that usleep is obsolete, but it offers more granularity tha sleep and is simpler to use than nanosleep; `man usleep` for more.
#define _XOPEN_SOURCE 500
#include <cs50.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
// board's minimal dimension
#define MIN 3

I am making a program that takes the user's family names, their ages, and where they live. At the end I will be eventually averaging out their age and also printing the names of anyone who lives in Kansas.
I can't seem to get the Kansas part to work properly though.. When I execute the code, everything else works perfectly, but the Kansas part doesn't even print. Is there something different I need to do when strings are involved rather than integers/floats?
Code:
#include <stdio.h>
int main ()
{
/* variable definition: */

I would like the following code to print: "Why doesn't this print?" and "I would like to print the sum of nc: 5". What am I doing wrong.
#include <stdio.h>
//Use to test ideas and formats//
main() {
int c, nc;
nc = 0;
[code]....
My result as compiled by gcc -o testing testing.c
This prints.
test
t1,e2,s3,t4,
5,
I have not figured out how to sum and print as the above code indicates, which complicates my ability to do many of the exercises in "The C Programming Language". I am using a MacBook gcc compiler and X code as well. I cannot get the last two printf functions to work. I did the temperature example with "while (fahr <= upper)" and the printf printed.

when i uncomment statements in the following ,it works perfectly fine for infix to postfix conversion.although comments are simple cout statements,, execution with cout statements as comments breaks in b/w.I have found this particularly with a^b-c.DevCPP is also showing similar behavior. I can't understand what's going on.I am working on code blocks.
#include<iostream>

#include<conio.h>
using namespace std;

I'm attempting to print a series of text from this loop, but for some reason all I am getting is the sum total and the number 1, like this
1 5175.11
When I want to get it for each iteration of the loop. I've cycled over this and compared it to my other loops I've used and I'm lost as to why this isn't working. I also tried using a do while but that didn't work as well.
for (double total1 = 0; total1 < goal; total1 + save_amt) {
total2 = ((factor - one) * save_amt);
total3 = (total2 / fr_interest);
total1 = total1 + total3;
months_dis = (months_dis + one);
cout << months_dis << " " << total1 << endl;
}

I want to create a vertical histogram in my code. I already made it go vertical but not the way I want it.
Example:
I want it like this:
Range1 Range2 Range3 Range4
And asterisks under each one, depending on the user input. (My code is below and doing it on here doesn't make it come out correctly)
But what I've managed to do is this:
Range1
*
*
*
Range2
*
*
Range3
*
*
*
*
Range4
*
*
Which I don't want. I want everything else to stay pretty much the same since I can only use some features such as Arrays and really basic functions.
Here is my code: (Worked fine last time I used it and I am doing it on Visual Studio 2010 (at uni) and 2013 (on my laptop)).
#include <iostream> //Start of code
using namespace std;
int MarkValueInput; //Mark entered by user
//Counter variables for ranges in While Loop
int counterlow; //Counter for low range
int countermidlow; //Counter for mid-low range
int countermidhigh; //Counter for mid-high range
int counterhigh; //Counter for high range

The function uses a "for" loop to print the given character the number of times specified by the integer.
How can I make a for loop to do that?
So.. my code looks like this:
// cpp : Defines the entry point for the console application
//
#include "stdafx.h"
#include <iostream>
using namespace std;
void printMyInteger(int myInteger, char myChar) {
[Code] ....
So.. here is my error:

I am working on a small simple program my program fills up a air plane with customers there is 2 levels 1 and 2 and it will put that person in the spot depending on being picked.
So far i made a boolean airplane with 10 spots I can enter 1 person into the airplane with no problem but then after he sits down i get a infinite loop? I assume i maybe have to use the continue statement I feel like there is something simple that im missing i want to add more people. here is what i have
class Program
{
static void Main(string[] args)
{ bool[] planeSeats = {false, false, false, false, false, false, false, false, false, false };

Using cin.sync() works great so far, but my program still breaks if you copy something with multiple lines into the console.
string test = "";
while(true) {
cin.sync();
getline(cin, test );
cout << endl << "test: " << test << endl;
}
However, if you were to copy this:
1
2
3
and paste it into the program, the output would be1
2
3
test: 1
test: 2
And if you press enter one more time:1
2
3
test: 1
test: 2
test: 3
The 3 finally pops out.
