I am trying to create an expression creator that prints the work out too, not just the answer.
Code:
#include <iostream>
#include <windows.h>
using namespace std;
void p1();
void p2();
void p3();
double P,P2,p,ans,ans2,ans1,restart;

this programm should in theory create a labyrinth but it doesnt and i really dont have the skill to pick up where i have been mistaken so gcc runs it but it crashes and it doesnt produce any remarkable results even when it runs....
for example this should you run it with these parameters .
5
5
appear something like this
10111
10101
10101
10001
11111
or like this
10111
10001
11101
10001
11111
but it only crashes....it works with recursion and it makes a array (which is Ptr) a set of 1 and 0 which 0 is the path and 1 is the walls...
Code:
#include <stdio.h>#include <stdlib.h>
#include <time.h>
int **Ptr;
int M, N, P, charge, i,c,j;
void Lab_creator(int vertical, int horizontal,int direction);

I have a program that makes change from an amount. It works fine, but the output is the correct output looped over and over. I have tried everything, but it still doesn't work. For example, a amount of 98 should print
3 quarters
2 dimes
0 nickles
3 pennies
but instead it prints
3 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
Why it's doing this?
Code:
#include <iostream>
using namespace std;
int coinscount(int& amount, int value) {
int tracker = 0;
int amountdimes = amount;

I am trying to link OpenCV to my qt project, but for some reason it doesn't seem to able to find my files. my .pro file looks like this
QT += core gui

TEMPLATE = app
INCLUDEPATH += /usr/local/include
HEADERS += mainwindow.h
LIBS += -lm -lopencv_core -lopencv_highgui -lopencv_video -lopencv_imgproc

mainwindow.cpp
FORMS += mainwindow.ui
I get the error message saying library not found for -lopencv_core and it is the same for the other ones.

I am using Qt Creator with VS2012 compiler.
I declared a QByteArray variable : T
I initialized it. Everything OK. I added the line :
Code:
T += "

What follows gives me an exception and I think that the issue comes from this added line. As I take a look at T in the debugger, I don't see any but a point .

I am writing a program to tell how long it will take for a loan to be paid off supposing the desired loan is 100,000, the annual percentage rate is 6, and the monthly payment is 1,000. What happens is after I run the program, I get the output of "-24.60" after the last month is paid off. I'm trying to get it to where the last monthly payment is only enough to make the loan 0. Then I want the program to end.

Okay so I thought I had this assignment completed properly last week. Last night I found a bug while playing the game.why won't the game end when the player guesses the correct number? The game allows you to finish using the max number of guesses even though you already guessed the correct number.

#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#define MAXGUESSES 6

I tried to create a multiple choice list and I want to assign the value of the answer option chosen by the user so I can use it later on in the code. Later on in the code i've asked how many people (p) want a drink and multiplied it by the chosen size to calculate the price c = p * n where c is cost, n is price and p is number o of people At the bottom i tried to assign parameters where depending on what option the user has chosen n will be assigned to the chosen value...

printf("SELECT TYPE OF PAINT:"); /*multiple choice of paint */

I've been trying to get the numbers for hours now but i can seem to get it right. Here's the problem below:
During the initial period, when the heater is not yet functioning at peak efficiency the heating will increase the temperature inside the building at a rate given by the following equations. During the initial period when the air conditioner is not yet functioning at peak efficacy the air conditioner will decrease the temperature inside the building at a rate given by the same equations.
Interval = (Time since turning on / 2.0 ) - 3.0
Factor multiplying Temperature change per minute = exp( Interval) / ( 1 + exp(Interval) )
These equations can also be used after the heating or air conditioner reaches peak efficiency. These equations converge to 1, so after the heating or air conditioner reach peak efficiency these equations will always give a value of 1.
the value of these equations needs to be multiplied by the RATE TEMPERATURE CHANGES. The RATE TEMPERATURE CHANGES is EITHER the change in temperature inside the building in degrees Celsius per minute caused by heat being extracted by the air conditioning OR the change in temperature inside the building in degrees Celsius per minute caused by the heat being generated by the heating .Temperature change in degrees per minute = Factor multiplying Temperature change per minute * RATE TEMPERATURE CHANGES
Temperature at end of this interval = Temperature at the start of the interval + temperature change due to heat escaping during the this interval + temperature change due to heat generated by the heating system during this interval + temperature change due to heat removed by the cooling system during this interval
i have a:
...rate of -.05 for heat escape w/o cooling or heating
...rate of 0.10 for heat escape w/ cooling
...rate of 0.125 for heat increase w/ heating
...Starting temp=38.00
...Time interval 3.50
I can't seem to find the temp at the ending interval? What i tried doing:
Code:
#include<iostream>
#include<cmath>
using namespace std;
int main () {
double intervals=0.00;
double tempPerMin=0.00;
[Code] ....
The temperature at the end of the interval is suppose to be 37.81 but i can't get the answer. I'm pretty sure this is a logical error from the equations i used but i can't seem to find it.
So I'm writing a program that will read a text file and it will do certain "functions" the text file will be like a game, and the program will be able to run many different games. The problem i'm having is in one of the "functions" i believe it's the one meant to get a correct choice from a file and a user input and put them into strings, it gets the wrong input. I know this because i tested both strings the "function" writes too. it gets the correct file answer but the user input is always "c" for some reason.
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <stdlib.h>
using namespace std;
int progfiles() {
[Code] ....
This is the code, most likely the section that is surrounded with "///" contains the problematic "functions." This is the command Line output...investigate why they're dieing or continue on your journey?(i-investigate/c-continue) got input and answer
i
c
i
Press any key to continue . . .
The got input and answer are tests to make sure it got both, the first 'i' is my input, the 'c' is what it says my input is, and the 'i' is the correct answer from the file. this is the part of the file that the program reads to get that output
"1 Do you want to go investigate why they're dieing or continue on your journey?(i-investigate/c-continue) 2 8 i 7 3 4 You continue on picking up speed to get to the egg first.. and.. Oh No, You accidentally bumped into the walls! 2 12 5 1 You go over, and as you realize the walls are acidic and that's why the other sperm are dieing.. 2 6"

I'm using MSVC++ and it builds sucessfully but somewhere something is obviously messed it. Once i try to debug it just shows weird numbers.

I am studying about recursion by myself and i want to make a recursive function that prompts the user to input the base and exponent and generate the final answer .

while(i<5)
i++;
count++;
printf("The value of count is: %d", count);
return 0;
}
It only prints: The value of count is 1. I'm confused on why it doesnt print the value of the count is 5
I need to make a program that prints certain pictures. My program compiles successfully. However, I cannot figure out how to view the ppm output. When i run the program i get a lot of random text.

It seems that it's just missing a space (and therefore a setw and setfill), but I found 2 problems:
1. The space needs to not apply to the first line.
2. I can't get it to make a space before each row without making a space between each column.
My current code is:
#include <iostream>
#include <iomanip>
using namespace std;
int main ( ) {
int rows;

I have tried putting in << setws and << setfills of various values but it seems to always apply to between each column as well as at the start of each row- what do I do?
I have a program that prints out pascal's triangle. One problem: it isn't a triangle. The output doesn't work. This is what it should print:
Code: How many rows: 4

1 3 3 1
1 4 6 4 1 and this is what it does print: Code: Enter a number of rows: 4

So i have this -
time_t t4 = time(NULL);
//and then some stuff
time_t t5 = time(NULL);
iElapsedYah = t5-t4;
fElapsedYah2 = iElapsedYah/iNumTimes;
printf("It took %f seconds", fElapsedYah2);
but it always prints 0.0000000, and i dont know why even though individually
iElapsedYah = not zero and iNumTimes = not zero
